With User:Dycedarg's help I've implemented auto-archiving, let me or him know if there are problems with it. Kmusser (talk) 12:52, 8 April 2009 (UTC)

Quick SVG's[edit]

Now I know that this isn't the best way to make svgs but ... you can use the site to do them automatically! It is a computer that is doing the work so sometimes the results aren't just right, which makes later editing harder but for certain (generally simple) images it works fine. ChrisDHDR 17:15, 25 April 2009 (UTC)

The bitmap is traced. We have those in the programs we use :) ZooFari 23:19, 4 May 2009 (UTC)
Like what? Inkscape? I've never noticed it. ChrisDHDR 18:34, 6 May 2009 (UTC)

Logged out when trying to make a map request[edit]

I clicked on the "make a request" link, and noticed I was logged out. I asked at the Help desk, and they suggested asking here. The person that suggested it tried, and did not have the same problem. I've tried several times, so it isn't a one-off glitch. I can navigate elsewhere without logging out, so I don't think it is a general cookies problem. (If someone notes I successfully filed a map request - I did it by copy and paste, not by clicking the link. Not a big deal, just wanted to see if it is a known problem with a solution. Sphilbrick (talk) 16:13, 4 May 2009 (UTC)

It doesn't log me out. What browser are you using? vıdıoman 10:22, 5 May 2009 (UTC)

Use of Google Map Embed in Wikipedia[edit]

I'm a fairly new user, but I've developed some private wikis elsewhere and was curious if there is any possibility of using Google Map embeds within Wikipedia pages. Specifically, I'm looking at some sections that could be expanded, covering legislative districts. There are certainly some graphical maps that could be used for this, but I was hoping that an embed would be possible to allow for greater detail. Gregwythe (talk) 08:42, 11 May 2009 (UTC)

I doubt it, Google Maps license is not compatible with Wikipedia. Kmusser (talk) 10:11, 11 May 2009 (UTC)
Thanks ... I suspected there might be either a copyright or security reason for not seeing the two together. Any advice for what would be an appropriate, allowed way to incorporate a legislative district boundary map? I've been using GIS tools to convert boundary shapefiles onto Google Earth/Maps for my personal use. If I were to create a graphic with that outline on any other map, I just want to make sure I'm using something that passes copyright muster. The maps provided by the state aren't terribly great, aesthetically speaking. Gregwythe (talk) 17:28, 11 May 2009 (UTC)
Assuming we're talking the U.S. here you should be able to put together a decent map using entirely U.S. government sources which avoids any copyright issues. I use GIS files from the Census and the National Atlas which is USGS. Kmusser (talk) 19:21, 11 May 2009 (UTC)

sources for a map request[edit]

Hello, not sure who is watching the page but I have a query. I need a map for the range of the subspecies of the Australian Magpie, and I have taken photos of the relevant pages in the two books which have the source material. I was about to upload and post here when I had doubts about what licence to place on them. Are they for me to label as own work, as I took the photo, or Fair Use? But using he range is altering, isn't it? Shall I upload them here or ask to send to someone? The reason there are two maps is one covers the range in Australia and the other has southern New Guinea. Casliber (talk · contribs) 12:02, 28 May 2009 (UTC)

That would be Fair Use if anything, but the rationale would be a little sketchy, e-mailing them to whoever takes your map request would probably be better. Kmusser (talk) 12:55, 28 May 2009 (UTC)
Thanks for the prompt reply. I was thinking that might be a better route. Now both editors who offered to help have retired or withdrawn for the time being so I need to find someone new.....Casliber (talk · contribs) 13:07, 28 May 2009 (UTC)

ArcMap styles[edit]

The convention set is really fine, congrats.

I wonder if some of you using ArcMap have prepared and/or shared style elements in respect to these conventions. phme (talk) 14:21, 4 June 2009 (UTC)

That would be clever, I haven't been that organized. Kmusser (talk) 13:10, 8 June 2009 (UTC)

SVG errors[edit]

I've created a map with Adobe Illustrator CS2, but I'm having trouble opening/uploading the resulting SVG file when I export. When I upload to Wikimedia Commons, it says the file is corrupted. When I attempt to open it with Firefox, I get an XML parsing error. Any suggestions? JKBrooks85 (talk) 04:57, 24 July 2009 (UTC)

I've had problems with Illustrator's SVG export as well. Sometimes you can fix it just by running it through Inkscape (open and save as simple SVG), if that doesn't work you usually have to edit the SVG file in a text editor to find the offending code. Kmusser (talk) 12:34, 24 July 2009 (UTC)
Firefox is usually good at pinpointing SVG errors within the file. Search the source with a text editor or use View → Page Source (Ctrl-U) + Find (Ctrl-F) in Firefox to locate the text mentioned in the error message. (If it occurs multiple times, the line number should narrow it down.) If the quoted text seems correct, it may be worth studying the line or two above it: perhaps a previous tag was not terminated properly. Certes (talk) 14:25, 24 July 2009 (UTC)
Thanks for the suggestions. I got it to work by running it through Inkscape after creating it in Illustrator. JKBrooks85 (talk) 22:39, 24 July 2009 (UTC)

Map request - Norfolk Broads[edit]

I need a map of the Norfolk Broads area creating for use on the List of drainage windmills in Norfolk. I tried using the existing Norfolk map with this result. I can lose #57 from the map as it was a pumping windmill rather than a drainage windmill. Can someone create a map just showing the Norfolk Broads area please?

Projected SVG maps direct from Shapefiles[edit]

I've recently created these maps using a command-line tool that I wrote to project multiple shapefiles directly into an SVG file. The bits are barely dry on the program, but you can see that it has a certain level of functionality. I am mentioning it here in case others could find it useful for their projects, and because I would appreciate cogent feedback. It is written in Perl, and I've developed and used it on Linux. It should be able to run on Windows if the Perl module Geo::Proj4 can be installed there.

The project is available for download along with some basic documentation and an example of its use (to produce the first map shown here). It's probably not for those who shy away from the command line -- it's syntax is a doozy. Among the list of possible enhancements I'm considering are either a separate config file to specify the rendering information for a map, or a GUI, or both.

In the interest of full disclosure, some post-processing in Inkscape was required for these, as is documented in the project. Most notably, all text is added manually. --Kbh3rdtalk 04:18, 8 August 2009 (UTC)

Very interesting ! I'm interesting to know clearly : for these maps, what made your soft ? what made you yourself in Inkscape ?
May you create a tutorial such as :
  1. Introduction/description ;
  2. what system/packages are need ;
  3. how to install + download link ;
  4. how to use (list of functions) ;
  5. gallery of examples.
I encourage you to put this there: Wikipedia:Graphic_Lab/Resources/Software/Kbh SVG script. Keep me aware of your progression ;) Yug (talk) 13:08, 4 November 2009 (UTC)
Note1: I don't understand clearly what make this script, and if it apply to world wide or USA only.
Note2: Your script may maybe help the large German map project there de:Wikipedia:Kartenwerkstatt/Positionskarten/Europa.
Please keep me informed. ;) Yug (talk) 13:08, 4 November 2009 (UTC)
I think that this perl script is fairly well documented on its github wiki pages, though of course improvements are possible. There is full parameter coverage, an example script, and a gallery of maps with a brief discussion of how each was made, albeit without the full command line. I think I chose the BSD license for it, so you can do whatever you want with it, and of course it adds no encumbrance to what you produce with it.
Apart from some external Perl packages (and that libproj library) that it depends on, there is no installation required for this program itself. I have intentionally architected it as a monolithic script that includes no modules of its own that need installing -- just run it from wherever you downloaded it to. Dependencies are listed there, but the list might not be 100% complete -- many perl packages came pre-installed with the Linux distribution that I use, and cpan installs other dependencies with little effort, so I probably missed some third-party packages required by the modules that I directly import.
Having used it a bit more myself, I have in mind a longer to-do list than what is shown, to make it more useful in more situations. I'd like to add data filtering by numerical comparison, e.g., which cannot currently be done with the regular expression matching that it has. I'd also like to color object based on numeric ranges. Getting the bounding box right should be made a higher priority, too, though it can be corrected afterwards with Inkscape. I really should get around to removing the SVG package to avoid its errors, minimize external dependencies, and streamline operation.
If this tool is not polished enough for your use, or if you require a point-and-click GUI, you might want to investigate Quantum GIS. It is supposed to have the capability to "print" directly to an SVG file. My inability to make that work with the current version was part of the impetus behind this project.

Move to commons tag for other-language Wikipedias?[edit]

Sorry, I know this is probably not the right place to put this, but is there an international {{Move to commons}} tag for other-language Wikipedias? I've found some images on other Wikis that are free-use, but don't know how to tag them properly. --Chris (クリス • フィッチュ) (talk) 17:35, 20 February 2010 (UTC)


Can someone help me out on this? Or at least explain the map in its current form. Thanks (talk) 10:30, 14 March 2010 (UTC)

Colourised data maps[edit]

I don't know if there is a tool exits already for this (probably there is - for JPEGs there is anyway) but I've cobbled together a website to generate SVG maps to show colourised data e.g. the typical GDP per capita maps, etc.. The site takes CSV data info form of ISO country code [comma] value and currently can generate a world or Europe map.

Based on feedback from here, I will (or not) add other maps and features. Link to site. Some sample data is provided. --RA (talk) 00:48, 18 March 2010 (UTC)

(I have revised county to country.)
What tools exists already for JPEGs? installed on the internet like this one?
Are there freely available tools to combine user-provided country-level data, a single numeric variable keyed by the ISO country code, with political outline data (shapefile?) provided by some geographic organization? And to select a region such as the European countries from the world political map? Or have you written those parts yourself? --P64 (talk) 13:45, 12 July 2010 (UTC)
This is amazing. Over at commons there are all kinds of requests all the time for maps showing diplomatic relationships etc - they take a graphist 10m to do, but it's time that could be spent on other things. You tool can give the non-graphists exactly what they need. Thumbs up! Jon C (talk) 22:59, 28 December 2010 (UTC)
JC, thanks. --RA (talk) 18:09, 13 February 2011 (UTC)

Maps, Maps, Maps ! Call for mapmakers ![edit]

Later correction: we later decided to rather focus on SVG map making tutorial. See this section. And to make some contributors calls. Yug (talk) 11:06, 1 February 2012 (UTC)

Is there some map makers ?? I was astonished to see that 90% of maps requests don't get neither comments, neither satisfied. We really need some users to come on the Wikipedia:Graphic Lab/Map workshop. People interested, please come ! Map making is a specific skill, almost easy to do, while maps, or relate technical diagrams are wonderful tools to explain and illustrate articles and knowledges. Inkscape (Download!) is a nice free software to create SVG maps. So come, come, come, choice one, and give a try ! We need MAPMAKERS there !!! :] --Yug (talk) 04:28, 13 April 2010 (UTC)

Curious about auto-generation of previews in wikipedia for large commons image[edit]

I uploaded a fairly large (53Mb) image to commons, Greater_Jerusalem_May_2006_CIA_remote-sensing_map_.jpg. Actually the orginal jp2 format image is much smaller than that but I converted it to jpg assuming that was a current requirement. The auto-generated preview (463 × 599 pixels) works fine in commons but not in wikipedia. The software in wikipedia seems to be trying to generate a 7,726 × 10,000 pixel preview. Seems odd. Should I do something about it and if so, what ? I'm not sure that it matters since the link to the commons file is there but I thought I should ask. I wasn't planning to reduce the resolution of the commons file since the full resolution is required and complies with policy. Sean.hoyland - talk 08:57, 26 April 2010 (UTC)

Looks fine to me, I'm seeing it's default preview size as 791 × 1,024. Kmusser (talk) 10:03, 26 April 2010 (UTC)
In wikipedia ? The plot thickens. I'm still seeing 'Size of this preview: 7,726 × 10,000 pixels' and no preview. Maybe there's a setting somewhere... ? Or perhaps it's client dependent. I use Internet Explorer. Oddly the image is fine when used in wiki articles. Sean.hoyland - talk 10:15, 26 April 2010 (UTC)
ah got it. there a preview limit setting under my prefs. That fixed it. Thanks. Sean.hoyland - talk 10:18, 26 April 2010 (UTC)

Shapefile manipulation[edit]

Using shapefiles and R statistical software, I know how to do some statistical analysis and generate some maps of area data (eg "Colourised data maps" above). What tools are available for these more basic tasks?

  • selecting a shapefile subset, such as sub-Saharan Africa from Africa or from the World? or New England counties from a county map of the United States? At wikipedia we have zillions of maps of the United States, and of individual states, but few or no regional maps.
  • extending a shapefile to incorporate user-provided fields of numeric data, such as every country's number of participations in the World Cup tournament? --P64 (talk) 14:02, 12 July 2010 (UTC)
I have learned more about R's own capabilities (not yet the hoped for answers). After reading some articles on geographic software and data, and some project pages on maps and graphs, some of my searches are more effective. Even writing my preceding note has been some help (eg, shapefile subset, there's a concept). --P64 (talk) 21:59, 13 July 2010 (UTC)

Category:Map images that should use vector graphics[edit]

I'm interested in creating new .svg files from raster maps. But i have some doubts, mostly because i don't know what to do after the file has been created.

  1. I have to copy all the features (colours, font size ec.), or may i use the ones suggested by Wikipedia:WikiProject Maps/Conventions?
  2. How to load file in Commons? Do i have to use a new name for file, or just upload in the parent one?
  3. How to categorize the "new" file? Do i have to place in same category of the parent file, or do i put it in the "generic" category SVG maps?
  4. What to do with the parent file? Has it to be purposed for deletion or not? Thanks a lotCiaurlec (talk) 21:17, 29 October 2010 (UTC)
I’m pretty new at this but here’s my 2¢ worth:
  1. I think for any current informational map it would be best to use the standard formats as much as possible. Illustrated maps and historical ‘replicas’ might be exceptions. (Thanks for pointing out that template BTW—I hadn’t come across it yet!)
  2. If you choose the “derivative work” link from the Upload page, you’re passed to a helper script that copies the description & licence info from the original file into your new one. It also lets you choose from a list of categories it’s guessed, based on the original description, and checks for filename conflicts. Unless the original name is excessively long or short, uninformative, misleading, or in another language perhaps, you might as well keep it the same: note that foo.svg is considered different from foo.jpg and foo.png.
  3. Outside my experience, apart from the above. But if the upload helper doesn’t come up with any good ones, you might look at how the original was categorized.
  4. I just tag it with Template:Vector version available; this template includes a note implying that keeping the original is sometimes necessary for licensing reasons. I presume there are bots that delete redundant images once they’ve been orphaned, but I don’t know much about the deletion process(es).

Countries within EU (rendering error)[edit]

The .svg maps of countries within the EU, such as [[File:EU-United Kingdom.svg|600px], are not displaying properly. Can someone here help sort it out? Ghmyrtle (talk) 09:34, 15 February 2011 (UTC)

I'm having the same problem when viewing File:EU-Hungary.svg via the English Wikipedia. Curiously enough this problem seems to be limited to EN Wiki only, as the same files are rendered correctly when viewed in Commons and other language Wikipedias as well. There seems to be some problem in the coding that retrieves the files and their respective info from the Commons, because the PNG "previews"/thumbnails of the files are replaced with a placeholder icon and the image dimensions are given as 0 x 0, while their size is given correctly (2.61 MB for EU-Hungary.svg). This seems to point to a permission problem within the EN Wikipedia itself (with the script having either insufficient permissions or lack of membership in the appropriate group). Could any of the admins (not the sysops, but guys who have the capabilities and privileges to actually "look under the hood") take a look at this? CoolKoon (talk) 17:59, 15 February 2011 (UTC)

I've done some research as far as the EU maps are concerned and found out that it's the EU maps of the following countries that don't work: Belgium, Bulgaria, Cyprus, Finland, Germany, Hungary, Italy, Lithuania, Luxembourg, Malta, Netherlands, Poland, Slovakia, Slovenia, Spain, Sweden, United Kingdom. All of the files use the naming convention EU-Country_Name.svg (e.g. File:EU-United_Kingdom.svg, File:EU-Slovenia.svg etc.), none of these are displayed correctly (at least the PNG files derived from them), all of them use a placeholder icon instead and basically have the same issues as the File:EU-Hungary.svg mentioned above. CoolKoon (talk) 19:12, 15 February 2011 (UTC)

Has someone changed the underlying coding or something? Sounds strange that it has just decided to develop this error. Jamesinderbyshire (talk) 14:54, 16 February 2011 (UTC)

Quality push: GIS mapmaking ! Call for mapmakers ![edit]

Hello ! I'm looking for partners to push toward GIS mapmaking, GRASS GIS, QGis ! Who have some basis in this ? which software ? Please let me know below ! Yug (talk) 16:31, 9 June 2011 (UTC)

Quality push: QGIS lesson 1: Create a topographic background[edit]

Later correction: we later decided to rather focus on SVG map making tutorial. See this section. And to make some contributors calls. Yug (talk) 11:06, 1 February 2012 (UTC)

Dear Map makers !
For long I watched at these topographic maps with admiration, curious about the way to do them. The standard way being to use GRASS GIS, a quite rude software, with lot of command line to input. But other softwares also do a good job. So I launched an assault on a rather friendly GIS software : Quantum GIS (QGis). I collected my week long experience and compiled it into a first basic tutorial, focusing on QGis and how to output the handsome Wikipedia Topographic maps, is now 90% done. These topographic maps make wonderful background for more complex maps, as aside. That's also the starting point toward vector topography, and shaded relief. Since I'm not a native speaker and despite my best will, this tutorial should include a bunch of strange sentences. So if anyone can help to copyedit this first lesson, that's really welcome. I'm also interested to get a tester and her/his feedbacks, installing the QGis on her/his computer, following this first lesson, and completing possible shortcomings. We have there the first BIG stone to upgrade the quality of the Map workshop's maps, let's go. Be bold : give a try !Yug (talk) 14:08, 9 June 2011 (UTC)

relief - level with continious colours, based on GIS approach.
Geolocalisation relief map of Italy
- topographic - level with discontinious colours, background based on GIS approach

Those look very good! Just one suggestion concerning the relief colors of the Galapagos map (and possibly also the Italy map): From 0 to 250 metres you go: light green-> dark green -> light green which is counterintuitive and confusing. bamse (talk) 18:38, 9 June 2011 (UTC)
I'd be willing to copy-edit the tutorial.

Inkscape to Illustrator : SVG ? any experience or comment ?[edit]

InkscapeAdobe Illustrator[1]: Inkscape's native format is SVG, ant it's also a format supported by AI, but the two implementations are not 100% compatible. Inkscape can also export into PS, EPS and PDF, that Illustrator recognize.[clarification needed] It is also advice to stay working on illustrator if you start do do so, since illustrator openning a SVG translate some of the SVG code, and will then just focus and work on this, while Inkscape will keep working on the standard SVG code.
  • Avoid transparent text ⇒ use path > Object To Path if need
  • Avoid transparent gradients ⇒ apply the gradient to the background.
  • Avoid image inclusion ⇒ Illustrator translate this as two objects: the image (scaled down!), and an invisble rectangle with the correct size. Need to correct it handily.[2]

Hello, a friend complained he can't use my SVG in illustrator. Did someone had troubles to open complex file to export from Inkscape into Adobe Illustrator ? Should I export to him with SVG, PS, PDF, EPS ? Did you made some tests ? some failures ? what are your experience and Is there a section about this on the graphic lab ? and in the whole, is Adobe Illustrator code fine wiki wikipedia and its collaborative approach ? Yug (talk) 06:01, 17 June 2011 (UTC)

After 3 hours of testing, it appears that the bug was not Inkscape's SVG code, it's Illustrator itself, which crash when the SVG (one path) is too heavy. Some other experiences ? Yug (talk) 14:08, 17 June 2011 (UTC)
They're both horrible. I've lost count of the number of times I've had to resort to manual editing to ensure W3C compliance. Illustrator seems to flatten all paths then group and clip them, which makes things too complex for alternative editors (this can happen the other way around too). Inkscape adds "sodpodi" tags all over the place, which, while not affecting readability in Illustrator, wrecks compliance. FWIW, the trick seems to be to save SVGs as "plain" in Inkscape and without the default "Maintain Illustrator Editing Capability" check box ticked in Illustrator. These don't solve the problem completely, but they help.  Philg88 talk 17:53, 12 August 2014 (UTC)

Animated China Map - Urgently Needs Replacing[edit]

South Sudan[edit]

So now that South Sudan has become a country, there are about a gazillion maps that need to be changed reflecting its borders. I'm wondering if it would be beneficial to create a different section of the workshop, or a separate category, or something, anything, where all the maps that need editing could be added to avoid swamping the main workshop page with a metric ton of requests relating to South Sudan. Or maybe just one monster request tacked at the top of the page where people can add a list (not thumbnails) of files that need to be modified? -MissMJ (talk) 20:24, 12 July 2011 (UTC)

I am sure the vast majority need to be changed, but would counsel that some maps may be used in history-based articles and should not have the borders changed. Also, the impression I have is that S Sudan will be widely recognized, but we should just wait and see that has happened. When I looked a day ago, there were only a couple countries that had done so and not UN yet. We should make sure our political boundaries follow general consensus.TCO (reviews needed) 20:48, 12 July 2011 (UTC)e
MissMJ, QGis may help greatly in this project of serial creation of locator maps. Naturalearthdata have a file about 'disputed territories', maybe south sudan is there. Yug (talk) 23:26, 12 July 2011 (UTC)(I'm going to bed)
Would it be possible to tag the images with "Categories: South Sudan map update project". Then the tag can be removed once the image has been updated. This would create a thorough list as people tag maps that are likely to be in need of an update. Delusion23 (talk) 12:22, 13 July 2011 (UTC)
Okay I've created commons:Category:Maps_needing_South_Sudan_political_boundaries. Any images that need South Sudan added that are on Commons should be tagged with [[Category:Maps needing South Sudan political boundaries]]. Anyone wishing to work on a map can then go there. There's already some good bases in commons:Category:Maps of South Sudan. Add a {{Warning|When updating this map with the borders of South Sudan, please upload a separate version.}} to any maps that shouldn't be overwritten. -MissMJ (talk) 21:07, 13 July 2011 (UTC)
Accessibility: MissMJ, create a template {South Sudan need} containing this category, or something like this, much more convenient to remember and paste. Yug (talk) 23:39, 13 July 2011 (UTC)
I'll get on it as soon as I figure out how templates that assign categories work. >_> -MissMJ (talk) 07:48, 14 July 2011 (UTC)

Manager need ! People need ![edit]

Yes check.svg Done: to do list updated. New SVG exercices for mapmaking (to open in Inkscape) published + stated the need for new editors. Non-free softs tutorial + QGIS unclear/unfinished tutorial issue : stale.

Marcus, I also started a clean up for the QGIS tutorial. It's not the priority, but the lesson 1 need a full rewriting, that's true. Yug (talk) 21:52, 1 February 2012 (UTC)

SVG tutorial finished ![edit]

According to previous feedbacks, I pushed toward the publication of this much need basic SVG mapmaking tutorial (rather than the too-high-level GIS tutorials). Review/copyedit welcome ! If feedbacks are positive, we can increase sharply its visibility. I also updated our "road map/priority list" : /to do, so we have a guideline to how to improve the project. Graphism is a slow, precise work. We mainly need more people, and more people digging in SVG mapmaking. So if you are interested ! Yug (talk) 11:26, 30 January 2012 (UTC)

QGIS Raster Calculator[edit]

Can anyone give me an example of how to stitch SRTM3 tiles using the raster calculator in QGIS, please? Cheers, Ma®©usBritish[chat] 10:03, 14 February 2012 (UTC)

Hello Marcus, nice to see you are exploring GIS map making. We still have a long way to go. Your question is out of my current knowledge, but I can redirect you toward the QGIS forum :
You have to create an account in 5 mins. Then go, say you are from wikipedia, and put your question very clearly (they are busy professionals) :) . For me, 2 questions failed so I did without, but I solved more than half dozen big troubles by asking them. That's a place to know. Best wishes~~ --Yug (talk) 17:38, 15 February 2012 (UTC)
If you have too many tiles, then just prefert this source :
  • Great for maps conventions ! NASA / USGS: SRTM3 (2000, Public domain). Specifics: topography layer(s), 1px= 93m (3"arch), 60⁰N-56⁰S (landmass only), datum WGS 84. Files: on command, 1 tiles.
--Yug (talk) 17:56, 15 February 2012 (UTC)
Merci beaucoup! Ma®©usBritish[chat] 10:47, 16 February 2012 (UTC)
QGIS is tiresome, is it not? I went to great lengths to Merge many SRTM3 tiles into 5x5 size tiles, to ease raster loading, only to find that the Shaded Relief plugin cannon handle the new size file (most ~50–100Mb) and gives a Python MemoryError. I hope the next version of QGIS deals with memory handling, or supports x64-bit better.. I have 4Gb RAM, it should have been sufficient, so this is a disappointing setback. Ma®©usBritish[chat] 13:14, 18 February 2012 (UTC)
1. Hello Marcus, first and for convenience, did you used the new NASA website for GIS, so you just have one big tile ? nb: I update the tutorial accordingly. Thanks for your feedback : )
2. What is your OS ? Linux, Windows, Mac ? I use Ubuntu. I will ask around, I think some other GIS mapmakers use Windows.
3. For shaded relief I met the same memory issue but I then believed it was my computer. Anyway, I see two ways to bypass it :
  • as I did, by using Galdem (see tutorial section for installation and use). I got better result with Galdem: about 5-10 times faster. (!) And never bugging. I use Ubuntu, Galdem should be available on other OS, tell me your OS, I will ask for help.
  • getting smaller GIS source. If the plugin crash, I guess it's because your .tiff is too big, too precise, for a too large area. If you use SRTM3, then move to a lower quality datum : ETOP01. I never tried, but that should reduce the tiff file by 10, so the plugin *may* handle it successfully.
4. Do you use SimpleSVG (plugin), will be need soon I guess. Or are you creating a png map ?
5. Yes, QGIS is tiresome, GIS mapmaking is tiresome to learn. Just a small dozen of wikipedian do it. I personnally learned from Sting, NNW, Sémhur, Bourrichon how they create great maps : slowly, carefully. You are progressing : keep asking questions when you need, I will answer to as much as I can. You can also upload a svg/png of your current work so I/we can follow your situation.
Best wishes ! Yug (talk) 14:38, 18 February 2012 (UTC)
Thanks, I'm using Windows 7 on my PC and laptop, I don't use any other OS. The NASA site works for me, but I often get errors such as "The Device is Full" (what device?). Is ASTER GDEM V2 the same quality detail as SRTM3? But I don't see how downloading the data as 1 large tile, which can be upto 20 tiles in area helps, as it also causes a MemoryError when creating Shading Relief. I have no problem with the tiles per se (SRTM3s atop a ETOPO1 basemap to hide the voids), I've passed learning that stage.
I'm now at the Shading Relief part, I'm upto trying en masse: I'm using Azimuth 320°, Elevation 60° with 0.000009 exaggeration, which works fine for individual SRTM3 tiles, although I have to convert them from TIFF to PNG in Photoshop, in order to completely remove the white alpha transparency which adds a faint but irritating tint. Not sure if there's any other way than this? It's a shame QGIS can't handle larger areas without memory issues. And the properties should be easier to apply to multiple tiles, without repeating long-winded processes. Some kind of "Select All" and "Apply to Selected" would be great addition to the software. QGIS needs an Adobe CS-style application to shake it up.. if QGIS was as friendly to use as Photoshop CS it'd be amazing. I wonder when QGIS 2.0 is due. Cheers, Ma®©usBritish[chat] 16:26, 18 February 2012 (UTC)
(please put numbers and line jump between your issues, that ease reading / answering)
Aster and SRTM3 have about the same quality : 1px = 31m. See our page "/GIS sources..." But GTOPO/ETOPO are far lighter, since 1px = 930m.
Ok, you know merging, good. : ) If you work fine with SRTM3's tiles, continue.
Yes, I did the same : I had to convert to PNG for the GIMP/Photoshop clean up, you do it right : )
I agree for the need of grouping. I ignore if there is a way to group them without merging them.
QGIS is already a major improvement for the free GIS softs, but It also still have a long way to go on the accessibility/functionality side. I'm actively involve in the SimpleSVG plugin development, which may one day be include in QGIS, thus adding a lot of convenience for SVG mapping. : ) From what I see, you manage well, you took the initiative to bypass some issues which is always the way to do : "find a way". Good. PS: if you learn some tips, consider sharing. Yug (talk) 17:13, 18 February 2012 (UTC)
Thanks. I'm aware that SRTM1 provides very high detail DEMs but only for the USA. I was wondering if there have ever been any high detail tiles produced for the UK/Europe, beyond SRTM3? I notice that even with shaded relief applied, a lot of the hill ranges in certain UK regions lack detail.. e.g. Cumbria, which means small area maps are not easy to produce without appearing somewhat inaccurate. Cheers, Ma®©usBritish[chat] 07:32, 20 February 2012 (UTC)
The ASTER DEM provides a global 30m resolution (the same as SRTM1). However, it is not in the public domain, see the terms and conditions. OSM isn't sure if it can use it, and the reviews of ASTER linked there indicate its actually not any better than SRTM3(!)
For the UK, OS OpenData provides a DTM. File:Central Cairngorms UK relief map.png shows its limit, which is about double the resolution of SRTM3. Tile merging will be a nuisance though.--Nilfanion (talk) 12:17, 21 February 2012 (UTC)

With what are you working then, Grass ? @__@ Yug (talk) 18:43, 26 February 2012 (UTC)
Okay, will do.. have been busy with other things lately, and am a bit side-tracked from Wikipedia and QGIS, but will get back into the swing of things. On a side note, I'm confused by the SimpleSVG plugin hype. I saved two test files, one via SimpleSVG, one via regular "Save As Image". They both saved an identical quality 553Kb PNG image based on what was in the main frame (i.e a screenshot), and SimpleSVG also produced an additional .svg file which appears to be little more than an XML wrapper that embeds the raster. I had expected, from the plugin name, for it to output some form of pure (bit simple) vector code of the map; sort of a Raster > Vector converter. Maybe I'm missing the point of this plugin, as I don't have Inkscape (I have Illustrator), but when I loaded the .svg file in my browser it just shows a red outline, the raster doesn't show. I use the "Print screen" method to get a custom sized raster output, though I would prefer SVG. Should I be outputting maps as a raster and using dedicated software like Illustrator to redraw it as a vector? Cheers, Ma®©usBritish[chat] 23:49, 25 February 2012 (UTC)
Example of nice raster topographic background for wikipedia use : fine : )
SimpleSVG: If you use both shape files and raster files in QGIS —which I assumed—, SimpleSVG is helpful. If you just use raster layer, then there is no special advantage over the print composer (which even provide more control for the output).
Until now, SimpleSVG point is to cleanly convert ShapeFile to clean SVG files, outputting a clean, well structured SVG to edit in Inkscape.
SimpleSVG haven't raster2SVG converter... yet. That may come soon (some few months?) I'm in contact with the programmer for that. That would be wonderful.
Second point. Currently, to convert from raster to SVG, it's an handcraft job. Based on a same main frame, we create a serie of black/white raster output with different altitude level :
  1. white < 0m < black
  2. white < 100m < black
  3. white < 200m < black
Then vectorize in Illustrator/Inkscape each black shape, thus creating the different topographic layers to color accordingly. It's in my opinion more fun and interesting than useful (for wikipedia usage). Full vectorization become a 'must have' if your usage is real-world professional publishing or conference's projection. Let's me add this to my to do list for the QGIS tutorials. ; ) Yug (talk) 09:42, 26 February 2012 (UTC)
Ah, I see. No I didn't test the plugin with anything but rasters; I have some shapefiles but they were not used. Seems like a fairly long process to go through each altitude, export it, vectorise it, colour it, make it a layer until all the levels form a purely vectorised basemap on which to apply geological features, locations, etc. I'm sure the end result can be brilliant, but it's a shame there is no automated process to do this far faster. I have yet to understand how the Raster Calculator works apart from a couple of very basic tasks. GIS is somewhat specialised work, and as is often the case with such software the pros don't like to publish too many tutorials/guides for amateurs to learn the job and risk taking away their work, as I expect they can charge quite a high price for well produced maps/terrain images, etc. Any guides, tutorials or information you publish is appreciated however. Cheers, Ma®©usBritish[chat] 10:00, 26 February 2012 (UTC)
Incidentally, the map of Korea is not a full vectorisation; as it still contains a raster element (the relief shading). It would be good if the tutorials provided a mechanism for vectorising that too - I'd imagine a similar process to that above but even more tedious (unless automated somehow).--Nilfanion (talk) 11:54, 26 February 2012 (UTC)
There is a plugin, SimpleSVG, which may include this function soon. We need to push the programmers into this direction. Yug (talk) 15:18, 26 February 2012 (UTC)
I agree with that, I find it irritating that we have to have one raster layer in an otherwise pure vector image.--Nilfanion (talk) 17:17, 26 February 2012 (UTC)
@Marcus, as always, you can explore around if there is an other solution or a new plug in. What I got 6 months ago was a 'Line creator', a function creating a line for all point with an altitude of 200m. This was actually not helpful, especially since most of these lines were open. Yug (talk) 18:48, 26 February 2012 (UTC)
The main benefit of Open Source is, of course, that it is free and often involves a lot of developers directing the software to suit many applications based on demand for greater functionality. The downside is that it only goes as fast as those developers can be bothered to work.. being unpaid means they don't necessarily reel out new updates weekly/monthly/quarterly, and the lack of commercial income, i.e. funding, means they don't always have the same interest in providing dedicated support, because the loss of a user isn't a lost paying customer. So it can be hard to press programmers into volunteering their efforts to making plugins, etc when other members of the team are not pulling their weight to develop the core, other plugins, etc at the same pace. I notice QGIS has a roughly "once a year" major release pattern, which is about the same as Adobe CS products, but imo quite slow when you consider how quickly hardware, OSs, and other technology moves. QGIS seems good at first, but feels very slow and lacking in many areas which I'm sure could be improved a great deal. I just noticed, whilst writing this, that version 1.7.4 was released a week ago.. so I need to update. Ma®©usBritish[chat] 19:22, 26 February 2012 (UTC)

Template {{Cite GIS}} voted for deletion. Help welcome ![edit]

There is a discussion to delete our project template {Cite GIS}. This template is useful for us, supporting our GIS mapmaking push by organizing systematically our GIS/satelite/NASA sources on the Wikipedia:Graphic Lab/Resources/Gis sources and palettes page. These sources make mapmaking a reliable science, with realistic topographic background, and systematically well geo-localized items (see GIS). From what I know, no other {Cite} template can do the job we, mapmakers, request here: introduce systematically these GIS sources and the usefulness for wikimapmakers. 8 fields which are not in {Cite map}. Namely: covered area, datum, projection, size_compressed, size uncompressed (world GIS are about 20 to 100Go files), tile size, tiles total, comments (for mapmakers), editor notes (for the dataset known bugs, limits). These fields are specific to raw materials, to databases files which can reach 100 Go, not to end products that are maps (a 2D drawing file). Currently, the fate of this template is voted by NON-cartographer. Also, your input will be welcome ! Yug (talk) 20:43, 3 March 2012 (UTC)

PS: they suggest merging with {{cite map}}, which may be considered, but not workable right now. Also, deletion is NOT acceptable. Yug (talk) 20:45, 3 March 2012 (UTC)

SVG and GIS tutorials push : news[edit]

Cheers, the tutorial for basic SVG mapmaking is ready : File:Tutorial-cartography_(basic).svg , that allow people with basic or no SVG skills to do nice SVG maps, and the first feedbacks are enthousiastic : ) It would be nice to tell people interested by cartography read it. What else on GIS push side ? Marcus launched an interesting talk and we thus made some progress. We are now about 5 graphists (--slowly--) who recently dogged into GIS mapmaking, that's good. I also saw GIS maps made by non-Graphic Lab users, so I started to invite them here and encourage them to give us their input. We need their advices ! If you meet some great mapmaker, drop them an invitation to join us on the WP:GL/MAP. This is to build a great cartographer team. Next, it will be need to move on the real battle field, there are many requests to check and to try. We will do a part of them ! and improve that way : ) That sound good. Cheers !

Need Help with Distribution Maps for Wikiproject Birds[edit]

Few WP articles on migratory birds of the western hemisphere have adequate distribution maps per the project's guidelines. I am updating articles on American swallows and swifts beginning with the Chimney Swift. Distribution maps are relatively simple, outlines of the continents and countries/states/provinces with the breeding and wintering ranges of a bird species highlighted in standard colors. Most print and on-line bird guides contain distribution maps. An example is the AllAboutBirds Chimney Swift article. Most of the print and on-line maps were produced in the mid to late 20th century and, for the species in which I am most interested, are out of date. If you go to the AllAboutBirds Chimney Swift article, click on "View dynamic map of eBird sightings" just below the map that is included. Note that Chimney Swifts are now commonly sited in Idaho, Arizona and parts of California. That breeding distribution is confirmed by the USGS Breeding bird survey data. In addition, the South American distribution is wider than previously shown. Creating an accurate distribution map that is current based on raw data should violate neither WP:SYNTH nor WP:NOR, in my opinion. Please correct me if I'm wrong.

I have no background in cartography. If someone here can point me to large outline maps of the western hemisphere that include outlines of countries/provinces/states, I may be able to use the GIMP to trace outlines and fill in distribution maps. A revision of the Chimney Swift article is slowly growing in my sandbox. I would appreciate help from those more experienced dealing with maps. Thanks in advance, DocTree (talk) 04:23, 2 June 2012 (UTC)

Standards for location maps[edit]

I put in a request a few months ago for a location map for the USSR, which wasn't fulfilled. Meanwhile someone has made one on commons, but it hasn't been done using GIS software, doesn't have co-ordinates and probably isn't right. I really need a location map for the Main Centre for Missile Attack Warning article so I've sat down and tried to work out how to make one. The tutorials don't cover these and I cannot find the standards anywhere, never mind a tutorial. Is this key in German the standard to follow? Does anyone know how the differing line widths are defined? Is there a tutorial on making location maps anywhere, even in French or German? I'm finding this really frustrating! Thanks. Secretlondon (talk) 22:04, 23 June 2012 (UTC)

Any map can be used as a location map. The secret is in the Wikipedia template and not in the map itself. You basically define the longitudes and latitudes that match the maps edges and the template will automatically calculate the x,y when you enter the coordinates for a city. The only catch is, this will work only for maps with cylindrical projection, which keeps the parallels and meridians as straight horizontal and vertical lines. For Canada, Russia and the USSR, very large countries at very high latitudes, cylindrical projection creates extreme distortion, that's why other types of projection are usually used for these countries. This complicates the calculation process, See for example the difference in the formula between Template:Location map Russia and Template:Location map Spain. Apparently users still active here cannot help you.
I'd suggest you post your request to the German Map Workshop or directly ask one of the regular contributors there (you can try User:NordNordWest who's one of the active regulars). The German workshop have more mappers and excellent ones at that. Most probably you'll have more luck there and they might be able to provide both political and relief maps. If for some reason you don't find a response there, you can come back here or post on my talk page and I'll try to concoct something for you using available Commons maps (not a location map, a normal one just for the missile warning article).
It seems, by the way, that most of the USSR maps we have now are of low quality and even wrong (esp. historical borders of East Germany, Czechoslovakia, Yugoslavia, and the extent of Aral sea) so any good quality map will be a huge improvement.
Hope that helps. Cheers! -- Orionisttalk 13:36, 24 June 2012 (UTC)
Thanks for your help. By following the tutorial I've got a vector map out of QGIS (and should be able to do a relief map too). It's how to work with it that I'm stuck with now. Secretlondon (talk) 20:14, 24 June 2012 (UTC)
I see you went with equirectangular projection (which is easier to implement but very distorted). But your map is messing the parts east of 180 long. For that, you might want to have a look at Template:Location_map_Russia_(equirectangular), it has some instructions on how to get a 180 crossing template to work. You might also want to remove administrative divisions of neighboring countries, as the map looks very crowded.-- Orionisttalk 08:20, 25 June 2012 (UTC)
Thanks again! It looks like the current maps we have are using the edcp projection - do you know how to select that in QGIS? There's nothing in the list of projections - does it have another name? I'd modify File:Russia edcp location map.svg but it misses out some of Ukraine, and some of the south. I've no idea where the formulas come from so borrowing them from another template is appealing.

Individual Engagement Grant Notification[edit]

Hello! I have posted a draft of an Individual Engagement Grant titled GIS and Cartography in Wikimedia. The grant calls for increased contributions of map content to Wikimedia projects through outreach to GIS and cartography communities that are currently not exposed to the idea and practice of contributing content to Wikimedia. This will be led by Darin Jensen, the Department Cartographer and a Continuing Lecturer in UC Berkeley’s geography department and Evelyn Hammid (myself), a UC Berkeley geography student and Wikipedia editor. We will recruit GIS and cartography courses in colleges, universities and possibly high schools into the US Education Program and assist these classes in contributing their projects to Wikimedia. We will also conduct outreach to GIS and cartography communities outside of schools to encourage freely licensed map contributions. If you are interested in this project or have any questions or concerns, please take a look at the draft and comment on the discussion page. Thank you and I look forward to hearing from you.

M4 motorway[edit]

Over at Talk:M4 motorway there is a discussion (between non-graphics experts) on how best to show the episodic construction of the motorway, in non-continuous stretches over time. At present there is a blocky, some would say confusing and valueless, diagram attempting to show this. I have suggested an animated map, which would require an expert here to devise it - something like this would do the job. It would be very helpful if a graphics expert or two could input to that discussion, with some ideas as to what best could be done. Thanks. Ghmyrtle (talk) 10:31, 16 March 2013 (UTC)

Overland Trail and two spurs through Colorado[edit]

I'm new to the map world, and I'm not ready to make an official map request just yet. What I'd love to know is if it would be possible to make a fairly simple map of the state of Colorado (File:USA Colorado location map.svg) that has the path shown in this photo: here. I apologize for it being so tiny, it's from a 1964 document on JStor and is probably copyrighted. Please note that only the dotted trail (not the dashed) would be required, and I've shown more of the surrounding states than needed to give the mapmaker a sense of direction. I've seen the cool location maps with floating dots on them, but I wasn't sure how an actual trail would be produced. Is this feasible? Again, not a formal request just yet. – Kerαunoςcopiagalaxies 19:05, 8 April 2013 (UTC)

SMOM Map Colours (SMOM_relations.svg)[edit]

In the map at, Canada is coloured orange based on relations with SMOM other than diplomatic (e.g., postal system cooperation). The English article on SMOM mentions that this situation exists for both Canada and Mongolia. Therefore, should Mongolia not also be coloured orange?

Base map of Asia with countries grouped for easy colouring[edit]

I am looking for a .svg map of Asia with countries grouped for easy colouring (Philippines is a pain to do manually). The following map uses th

Are you aware of any other .svg maps of Asia with countries grouped for easy colouring?

Thank you.

What's wrong with Asia_countries-gray.svg? Its projection actually looks much better than Location_Map_Asia.svg (which seems to be cut from the world map in Robinson projection). Hellerick (talk) 09:01, 3 June 2013 (UTC)

Are all of the Cartographers gone or something?[edit]

Ok! So about a five days ago I put a request in for a new map of the Sasanian Empire or at least an improved version of my map of the Sasanian Empire that I made. See here: So far no Graphist has responded to the request at all. I am not sure if the Graphists are supposed to make a response and the Cartographers make the maps after the response or if the Cartographers make see the request and make decide to go ahead and make the map while leaving no response to the user who requested it. I do not mean to sound rude if I am, but I was just wondering why no one has responded to my map request. Regards. Keeby101 (talk) 05:54, 20 August 2013 (UTC)

Summer 2013 call for cartograpahers ![edit]

As noticed upper, we lack PNG or SVG cartographers ! It's time to call for users, graphists, who may be interested in map making and to get some graphic competences ! Images, maps are one of Wikipedia's sides where we can contribute with fun while getting graphist skills. We do have ressources (location maps! SVG map tutorial) which allow to satisfy most requests. Yet, we have to connect them more with potential cartographers. Let's push for more clarity while calling for graphists to get involve. If need, let's reset the list of requests, wipe it, keep a hand of successful and pretty cases, so we restart on a fresh and clean ground. Yug (talk) 06:07, 21 August 2013 (UTC)

Are Cartographers on the Map Workshop capable of making pretty maps ?[edit]

This map seems to use Data Themes > 50m-bathymetry as background.

I was just curious if the cartographers on the Map Workshop were capable of making a map like the one I linked in the title of this topic, or a map like the File:Kievan_Rus_en.jpg ?

Yes, a hand non-english Graphic Lab editors are able to design such maps: NordNordWest, Sting, Bourrichon, Séhmur, myself. There are also a hand of native English speaking cartographers who are able to design such maps but for some reasons they are upload maps on their side, without joining up and showing up their work on the lab. These maps are indeed very elegant and charming, but also quite time consuming depending on both the technology you use and the details you input. I heard some cartographers saying that GMT is quite convenient and rapid to produce such maps. I myself use other ways (QGIS, console : gdal, Gimp for image processing, inkscape) which give more control but need 2 working days do design a such maps. There are lot of trial, fail, redo.
It would be good to know is those independant cartographers may jump in to share their tips for faster GMT mapmaking. Google may also help you, there are tutorials around. Just need the will to invest a weekend in it for a map which look like you wanted. Yug (talk) 08:49, 29 August 2013 (UTC)

Ok, on regards to this part:

  1. Open in some GIS software (QGIS)

I am having the biggest trouble with that.. Do I open it with the apps, bin, icons, lib, share or etc part of the QGIS Lisboa? I have WinRar and I can't open this damn Natural Earth Data as long as it is stuck in a zipped file called BATH_50M... I need help! :( Keeby101 (talk) 18:46, 31 August 2013 (UTC)

1. You indeed need to unzip first.
2. unzip > BATH_50M.psd in Photoshop. (see webpage saying: Rasterized 10m vector polygons in a layered Photoshop file that you can manipulate for color and then save a GeoTIF —use with the provided TFW world file. Optional reference layers include an ocean mask and land shaded relief.)
Note: The image is very, very, very big. My 2Ghz CPU + Gimp has difficulties to handle it.
3. Which OS do you have? Do you have Photoshop ?
4. Are you familar the Console ? (may sometimes be easier)
5. What are the W,S,E,N border of your area of interest on an plate carrée map ? Yug (talk) 06:45, 1 September 2013 (UTC)

I do not have Photoshop. I have Quantum GIS Lisbona. I know how to use Photoshop very well and I might just download it because Quantum GIS Lisbona is not working out quite the way I planned. I am not familiar with Console. On regards to the W,S,E,N border of my area of interest on a plate carree map, It would be the entire Middle-east/Central Asia area that would also include Egypt.

SVG locator maps (all of them)...[edit]

I hope I'm not opening up a can of worms here... In investigating a map request, I checked a couple SVG locator maps in Illinois. While the PNG thumbnails for these images worked, opening the SVG only produced the red box of the located county, with no other county outlines or state outlines. I expanded my search further out, and found that all the county locator maps of all (so far as I've checked) would not render properly. Since I use Chrome, I decided to check other browsers. Firefox also produced the bad image, while IE did produce a fully rendered SVG image. So I decided to check the images with the W3C validator, and the SVGs are not properly formatted. Do these ALL need to be corrected? As a test case, I worked up an updated SVG image: file:Jo Daviess County Illinois map test.svg, to compare with the old version: file:Map of Illinois highlighting Jo Daviess County.svg.

Since our objective is to provide in-article maps, I would say we don't *have to* fix that. Maps are properly rendered in PNG, end users are satisfied, priority is low. There is also a US location maps guideline & project designed by user:Shereth which was planing to programmatically redraw all these maps. It may be good to support and complete this last project, so all these maps are updated. Yug (talk) 11:56, 11 September 2013 (UTC)

Wikimaps Atlas: generating thousands base maps[edit]

Hello all
As you may know, I have been involve for years into the Graphic Labs as well as its Map workshops. I've been mainly busy with connecting the French, English, German, Spanish labs so best GIS resources, practices and toolboxes are shared, but also synchronized so we all work more efficiently and with similar color-schemes. At the Map labs, we've been aware for years that the heavy part of an high quality maps is an accurate GIS based background (base map), while on the other hand the added value is actually within the encyclopedic facts we select to hand-draw into the map's semantic layer. We also had talks dreaming about a centralized, automatic system to design these base map, and which could update them ALL whenever we update our map guidelines, or whenever a new country is created (remember South Sudan? with article editors suggesting us to redraw ALL wikipedia's Africa and world maps ?!). It appears we now have the technologies, skills sets, proof of concepts, a road-map and a proposal to do so. User:Planemad, who created the first map toolbox about 2006, today a webdevelopper, and myself (User:Yug), who created the Labs, maintains our map conventions up to best practices, and pushe for GIS map making are both, as Wikicartographers, deeply aware of the difficulty and needs we have. Having both map making oriented coding skills (JS, D3js, topojson, Makefile, gdal, wikidata), we've been busy along these 3 past months exploring to possibility to create a such system. It is now within reach. We can data-mine the name and bounding boxes of all administrative areas, then generate SVG location_map and relief_location_maps for each of them according to our map guidelines. Generated maps will also be strictly & consistently XML coded, opening the way for interactive maps. The vision sound great and doable on short term, Engineers at the WMF encouraged us to applied for a Wikimedia Foundation Grant request, so we did it, and there it is:

Due to the scale and complexity of the project, the total grant request is for an amount of USD 10500, which will allow both of us to work on this project full time for a period of 3 months to really get it DONE. The grant also includes a budget to hire external consultants where required to accomplish the stated goals. We want to provide first some thousands elegant basemaps for all countries and provinces of the world, but more importantly, we want to provide a open source centralized system able to easily update all these maps. Secondly, if you graphists and cartographers provide this system with a title and a WNES bounding box (West/North/East/South, decimal degrees), the system will give you back within minutes both a location_map and relief_location_maps of the area, so we could focus on designing the encyclopedic layers. We fight for that. The proof of concept were GIS+D3js result into a nice SVG wikimaps is here (Yug), an example of Wikidata-connected multilingual interactive map is there (Planemad), and this kind of stuff sound just handsome. Wikidata open interesting doors, especially in the direction of multilingualism and gradient maps.
What you can do: The WMF grant jury have some central criteria. They want to know :

  1. will/does these basemaps will help you -graphists and cartographers- to design high quality maps ?
  2. What do you think about this idea ? The project goals currently focus on 2 styles : lat/long location_map and relief_location_maps.
  3. But our code will be open source, so you will be able to hack it, add some few code :
    • to generate other layers, gdal give promising hints for shaded reliefs, in bitmap or SVG.
    • to generate other projections. D3js give us promising hints for orthogonal projections, and it seems possible to have odds projections such Albert_conic & Co for polar areas.
    • to integrate other GIS data, such animal ranges, etc.

The project also need your support there: meta:Grants:IEG/Wikimaps_Atlas#Endorsements
Last note: While the project will mainly rely on Planemad and myself, it is a Map workshop project, we need this support and system to smooth our cartographic work. So I wish to keep it within the map workshop, sharing GIS tricks, resources, ideas. Fight ! Yug (talk) 09:43, 19 October 2013 (UTC)

ShareMap - Wikimedia grant - community endorsment needed[edit]

Hi members of Graphics Lab,
ShareMap is a collaborative map creation tool and is currently applying for Wikimedia grant to continue project development.

There is already dozens of maps created with ShareMap, you can see them all here:

We will be very happy for endorsement, opinions or even criticism from all community members on Wikimedia grant project.

The ShareMap idea is perfectly coordinated with other project requesting for grant meta:Grants:IEG/Wikimaps_Atlas. All Wikimaps Atlas scripts and practices can be easile reused within data generated from ShareMap to generate pixel perfect map from user contributions.

Both the Wikimaps and Sharemaps grant requests are coordinated. Wikimaps are for short term, stand alone maps, which perfectly fit in current wikipedia cartographers' practices. Sharemap is actually a long term, but more powerful cloud approach, which is the future of in-wikipedia map making. Both initiatives may also eventually merge, thus recycling hundreds high quality SVG maps. Most importantly for now, both initiative need your support. Yug

Hello all. I'am happy to confirm. Jacob and his partner have made an amazing job at and have from the beggining asked advices to satisfy wikipedia map making needs. Recently, Jacob and myself have been coordinating to make these 2 grants requests (Wiki Atlas & Sharemap), which will assist cartographers by satisfying 2 different needs. These 2 grants requests are the first ones from & for the wikigraphists, for images & maps within the Wikipedia. We indeed want the Wikimedia foundation to start to take illustrations seriously, to invest a bit for images and graphic design, and maps are first. These 2 grants request are still in competitions with ~30 others grant request, mainly about articles' textual content and community management, where the WMF spend most of its IE Grants' money. All grant request will not get validated and founded, these 2 IEG request need your support so one or 2 of these heavy projects get founded and really achieved.

Tricks : Do you use the {Graphic_lab|en|map} template when uploading ? (and others tricks)[edit]

Hello all,
I don't know why, nor what happened, but thanks to Begoon, Tobias (and Keeby101!), for the first time the English map workshop cartographers designs great GIS maps. We start to be serious about cartography, that's nice, time to the English speaking to kick back : ] From recent works I though about some tricks which may be useful to know.

  1. Upload an SVG to check the end result. SVG are better for later translationss. But you probably noticed that MediaWiki use a SVG-to-PNG renderer so Wikipedia article display .png miniatures, which, for sure, all web-browser can a handle. So... your perfect SVG when on your computer, while moved to commons and associated with PNG versions, mays now have some tiny changes and annoying little bugs. Typically, the renderer have difficulties with fonts, so your labels may get a bit bigger and out of the frame (in the rendered png). The German cartographerd thus upload png that no one can reedit. The French cartographers upload the svg, check what is bugging, then upload a new version which.... can be translated.
  2. You are the boss of the map you design, take the lead to push your map into the article(s). Sometimes, the user who requested the map just disappears. So when you think your map is better than the current in-article situation, go ahead, push your maps into the article so readers may enjoy it.
  3. It's important to give a clear name to your maps, generaly File:{TITLE}_{YYYY}_{ERA}_{TYPE}-en.svg , the TITLE can be the article article's title (ex: Serbian Empire), YYYY_ERA the year and era (ex: 1355_CE, ca3000_BC, etc.), the TYPE is generally missing for pure SVG maps but when you do GIS cartography they it may be relief_map (for relief), relief_map-bw (for relief in black & whine), _location_map (for administrative), then the language iso of the wikipedia is important since your maps will likely, some time, be translated. We use -en for English, last is the extension. I think this is within our map toolkits/convention, but not sure (the historical map guideline is poor and should be revamped!). This is actually quick to get.
  4. When uploading your work, remember to also add templates:
{Graphic Lab|en|map} (iso and work type without majuscule, for all maps)
{translation possible} (wonderful tool to ease translation of your work by non-svg editors!)

That's all I can think of for now. I will find some other tricks in coming weeks. If you have any question, please ask & propose some solutions! Yug (talk) 11:17, 1 November 2013 (UTC)

Thanks for those tips! I didn't know any of those things. It would be cool if we could somehow pull the labels for places from Wikidata into the SVG and people could just translate the item on Wikidata. Maybe in the future :) --Tobias1984 (talk) 18:50, 3 November 2013 (UTC)
5. For historical maps and peripherical areas, use blur colors and blur words (legend) such as "temporarily under influence", etc. : ] Yug (talk) 17:22, 7 November 2013 (UTC)

Should I be a co author[edit]

Removing gridlines[edit]

Not when it's a bitmap image (jpg, png, gif) like this one. You have to retouch every pixel where there is a line and depending on the image it can be more or less time consuming and difficult, but it always takes time. --Goran tek-en (talk) 23:27, 12 December 2013 (UTC)

Tangential comment[edit]

This is almost certainly the wrong place for this – but I don't know where is the right place.

My collection is here. I will welcome any comments. Maproom (talk) 20:13, 16 April 2014 (UTC)

Question about KML mapping regarding to copyrights[edit]


I´ve been making KML files using Directions in Google Maps, that way I don´t have to draw the route but I simply use the routes that Google draws for me. When I´m done, I download it as a KML-file, which simply is a big list of coordinates. Am I allowed to use this functionality, as you can see I only use raw data, no imagery. An example of a road for which I made a KML using Google Maps directions is Idaho State Highway 28 Thewombatguru (talk) 20:09, 13 May 2014 (UTC)

IANAL but I am pretty sure that copyright law covers data. Maproom (talk) 20:44, 13 May 2014 (UTC)
Data is not copyrightable in the US; this is why, to some extent, the GL exists as to recreate figures based on uncopyrightable data in a free license form. In the UK or other places , sweat of the brow may allow such to be copyrightable.
While a database can be copyrighted if there is sufficient creativity involved in it, the creation of the KML file - an XML-coded list of coordinates - is not sufficient for that. --MASEM (t) 21:58, 13 May 2014 (UTC)
Excellent answer Masem. I'd just add that because all Wikipedia's maps are hosted by Wikimedia servers based in the US, the underlying data is not copyrightable. The situation is different in other jurisdictions (for example in the UK Crown copyright applies to all Ordnance survey data). However, OpenStreetMap data is licensed for use under the ODBL across all jurisdictions. There are also free tools like Maperative available which will convert XML data to SVG, which makes life much easier.  Philg88 talk 08:09, 14 May 2014 (UTC)
Thank you for that User:Philg88. That tool just eliminated the painful process of dealing with qgis to convert my KMLs to svg. - Floydian τ ¢ 23:18, 19 May 2014 (UTC)
You're welcome, Floydian. There are also some useful things that you can do vis-a-vis KML/XML with JOSM and the OpenData plugin. Ignore the OpenStreetMap functionality and just use local files. Cheers,  Philg88 talk 05:18, 20 May 2014 (UTC)


Location of ? in ?.

This question is rather tentative as I really don't know whether this has been endlessly discussed nor do I want to insult people who've done a lot of hard work. But generally Google (and a whole host of others) have the edge on anything in Wikipedia because they use Ajax to be able to scale a map at will. For instance, the map shown isn't a bad attempt to show a locality within a larger one, but it really doesn't work. (Could you guess where it is or what it shows?) I usually have to click on the coordinates to get to Google or OSM at this point. And there are probably thousands of such carefully drawn maps in WP. Might it not be possible to use scaleable OSM maps directly (with a sensible initial scaling) to do better? Chris55 (talk) 14:35, 12 August 2014 (UTC)

Chris, this issue is know be wikipedia "volunteer" community there reach its limits. Using OSM is tricky :
  • Direct embeding of OSM data is staled since Wikipedia doesn't want to let any other web company, even, to see your IP. (privacy)
  • Rebuilding locally OSM needs technical expertise, and Human Ressources investment haven't been done... aside of passionate voluteers who lead the "Wikimaps" initiative, which gather tons of good will, but where each member work on his spare time.
  • OSM data itself is actually messy. For the past 3 years, National GIS agencies started to open their data, allowing dump of accurates polygons into OSM, which sharp increased OSM quality for these countries. But this coverage is very unequal, so we can't trust OSM for a world wide project.
  • The Wikiatlas project that I lead is a recent project to bridge a bit Wikicartographers best practices (map guidelines) and available GIS data (NASA,, OSM), together with smart technologies (D3js, Make). But we reach humans, and sources limits. As we are just 2 paid students and open GIS resources are still unstable as we go from Countries (L0) to Provinces (L1) levels. Natural earth data just revamped this L1 level, and injected some misunderstanding (L2 levels as L1 for France!).
To make it short, the field is not mature enough on the Open GIS side and Wikipedia haven't invest enough to make the best of available resources. Yug (talk) 15:31, 21 August 2014 (UTC)
Glad to see there's someone interested! I don't do twitter I'm afraid so I'm not clear about your project. But I realised that English Wikipedia is not the only place this would be discussed and a fair bit of work has been done on Meta, particularly OpenStreetMap (the Wikiatlas project is clearly different to yours). The Germans contributed money for a toolserver project but that all seemed to happen in 2009 and very little has matured since. I can understand that OSM is best for N.Am. & Europe, but won't that be the case for any open project? I can also understand that Wikimedia would not want to depend on external servers, but OSM material can be periodically dumped to a Wiki server and can therefore be independent day-to-day. I see there is at least one example of an OSM layer on the English Wiki but that's not exactly what I think is needed. The OSM terminology is 'slippy maps' and at least one person has experimented with them on a Wiki. OSM also has a MediaWiki extension for simple maps which must have the simplest syntax:
<map lat="51.485" lon="-0.15" z="11" w="300" h="200" format="jpeg" />
inserts a map which can be clicked on to make it full page. So the ideas are around. Maybe just more resources and urgency are needed. Chris55 (talk) 09:44, 22 August 2014 (UTC)

Thoughts about file formats for maps[edit]

Example 1: an .SVG map

Some of the maps used on Wikepidia have a vector format, SVG; some have a raster, or bitmap, format, including .PNG and .JPG (maybe .GIF is still used). It is sometimes claimed that .SVG is uniformly better. In fact each has its advantages, as I shall show with two examples from the current workshop page.

Someone wants the map of Europe to the right changed, making the Crimean peninsula green instead of yellow, as it is now part of Russia. If it were a bitmap this would be easy: draw the border across the Isthmus of Perekop in white, and floodfill the peninsula in green. But this image is SVG, and the SVG format, for good reasons, does not support floodfill. So I have not volunteered to edit this map. I am sure it could be done by someone with the right tools and the knowledge of how to use them, but I lack both.

Example 2: a bitmap map

Someone else wants the map of Switzerland to the left changed, with the country and language names translated from German into English. If this were a sensibly-constructed .SVG, this would also be easy: find strings such as "FRANKREICH" in the file, replace them by "FRANCE" etc., and maybe change their x-position so that they are centred in the right place. But it is a bitmap. The change would involve removing the German names, repairing the damage to the frontiers, rivers, etc. which they overlaid, and writing in the English names, damaging the mountains, rivers etc. again.

It would be good if maps could have all the text represented internally as text as in an .SVG, but the other features in a bitmap format. Then both types of change could be made easily whenever there was a need to maintain or update the map.

This could be achieved as follows. The .SVG format allows an image to contain an embedded bitmap, given in the .SVG file as a url or path/filename of the embedded image. I believe that this would work well, with both files on Commons. The main disadvantage is that one map being two images might confuse editors. An incidental advantage would be that maps like the linguistic map of Switzerland above could be a single bitmap, embedded in an English-language SVG for use in en:Wikipedia, a German-language one for use in de:Wikipedia, etc.

I am tempted to try uploading such a two-file map to Commons, to see if anything goes wrong. Maproom (talk) 19:57, 10 October 2014 (UTC)

Without country and language names.
Well — it didn't quite work. I stripped out the German-language text, and uploaded the result, as seen to the right. Then I wrote a simple English-language .SVG wrapper to include it, which reads
<svg xmlns="" xmlns:xlink="">
  <image x="0" y="0" width="1000" height="712" 
xlink:href="" />
  <g style="font-size: 32pt">
    <text x="560" y="50">Germany</text> 
    <text x="60" y="280">France</text>  
    <text x="770" y="610">Italy</text>  
    <text x="860" y="270">Austria</text>        
  <g style="font-size: 16pt">
    <text x="735" y="290">Liechtenstein</text>  
  <g style="font-size: 28pt; font-family: sans-serif;">
    <text x="130" y="440">French</text> 
    <text x="360" y="270">German</text> 
    <text x="560" y="530">Italian</text>        
    <text x="670" y="440">Romansh</text>        
English-language version of Linguistic map of Switzerland.svg

and uploaded that. The results are shown below.

I don't understand what went wrong. The same file that I uploaded, with its xlink to its included file on Commons, works on my local computer. Maproom (talk) 21:25, 10 October 2014 (UTC)

I now understand what went wrong. I tried repeatedly to upload the file using Chrome. About seven times, it unhelpfully said "Aw, Snap!". Twice, it changed the entry in the edit box for the file I was trying to upload. And once, it succeeded, but I now see that something removed the <image> tag from the SVG, resulting in the text-only image you see to the right.
Today, I tried with other browsers. They were all more helpful than Chrome, reporting back from Commons "This file contains HTML or script code that may be erroneously interpreted by a web browser. See the FAQ for more information." So it seems that Commons doesn't like image files with embedded image files. I wonder if there's a way around this. Maproom (talk) 13:03, 11 October 2014 (UTC)
Encapsulating a raster file within a vector format wrapper is a waste of storage space, a waste of computing power and a total waste of time. Only use an SVG to contain a raster if the effect can only be achieved that way and then only as a last resort. It's a vector format for a reason, and there is no reason whatsoever for an SVG map to contain a PNG version of the map within it. It won't scale like a vector, it won't print like a vector and most likely the map started in vector form in the first place. So please don't upload SVGs with deliberately embedded raster artwork. A Gaussian drop shadow is one thing, but a full map is quite another. -- (talk) 18:24, 14 October 2014 (UTC)
So what method would you recommend, for the effect I am hoping to achieve? Maproom (talk) 20:41, 14 October 2014 (UTC)

Batch removal of watermarks from SVG-files?[edit]

Hello, is it possible to remove watermarks from a whole batch of SVG-files at once (with a script or tool)? My question is referring to the Commons UNOCHA maps category, which was uploaded with watermarks (against current WP:WATERMARK policy, but that doesn't matter here). After some random checks all identical watermarks seem to be in the lower right corner, either on their own or embedded in a small surrounding box (to create a bit of distance to other map elements). Besides some basic editing skills, I am completely ignorant in more complex image editing - any advice would be appreciated. GermanJoe (talk) 20:07, 7 November 2014 (UTC)

At Wikipedia talk:Image use policy#Clarification needed regarding WP:WATERMARK I suggested the use of the visibility="hidden" attribute. --Redrose64 (talk) 16:27, 25 November 2014 (UTC)
Have commented over there :). Thank you for the notice and your help. GermanJoe (talk) 16:29, 25 November 2014 (UTC)

Is this project still active?[edit]

Just wondered who (if anyone) makes maps still or whether this project is now defunct? The Rambling Man (talk) 20:34, 16 November 2014 (UTC)

It's still active, there just aren't as many editors participating as there once were.  Philg88 talk 20:53, 16 November 2014 (UTC)
Ok, I guess the fact there are still requests outstanding since April should have given the game away. I guess it's pointless adding further requests since the page is neither maintained nor updated per its own instructions. The Rambling Man (talk) 21:08, 16 November 2014 (UTC)
The requests outstanding since April are ones that no-one is competent and willing to undertake. Some requests are fulfilled promptly. Maproom (talk) 07:35, 17 November 2014 (UTC)

1-2 books for English speaking map makers ![edit]

Hello cartographers,

The Wikiatlas project is soon delivering its online tool for easier WP map making. We took lot of inspiration and courage from your elegant work and would like to offer one book to some active cartographers of the English workshop :)

Please help me to identify 2 leading wikicartographer here, I will handle the purchase thanks to WMF funding, and amazon may, with luck, deliver to you for Xmas. Also, with lot of geeky admiration, thanks for all and Merry Xmas to you ! --Yug & Planemad 16:39, 8 December 2014 (UTC)

Philg88, any local name coming to your mind ? Yug (talk) 00:47, 12 December 2014 (UTC)
@Yug: You mean the name of an editor or the name of a book? Cheers,  Philg88 talk 07:16, 12 December 2014 (UTC)
I need 2 English wikicartographers names, I'am not here recently and can only think about user:MapMaster (if you hear us!), who would totally deserve it, but is not active anymore. I admire MapMaster works, yet it would make more sense to encourage emerging map makers. SVG editors working a lot on maps are fine too. Any names in your mind ? Yug (talk) 10:27, 12 December 2014 (UTC)
Well, apart from me, the only recently active editor seems to be EuroCarGT. I don't know if Maproom is still around.  Philg88 talk 17:06, 12 December 2014 (UTC)
Philg88, there is the Xmas tree to talk to ^^. I just sent it to Goran tek-en since he is maintaining file:Maps_template-en.svg and design cool svg maps as well. These books are thanks you notes from the community, enjoy ! Yug (talk) 19:58, 15 December 2014 (UTC)
ThanksYug! Apologies to Goran_tek-en for forgetting to mention him and request to Santa duly filed! Best,  Philg88 talk 23:00, 15 December 2014 (UTC)

I want to make a world map, with countries colored according to data[edit]

Hi. I'm not sure whether this is the place to ask. I would think or at least hope that my question has an easy answer, ha ha.

I want to make a map to place in a Wikipedia article. It would be comparable to File:Map_of_world_countries_by_GDP_(nominal)_in_US$.png

I'm thinking that there must be free software whose input is: 1) a table, each row being the name of a country together with a number, and 2) another table listing colors and data ranges. Then the program would produce a world map colored according to the data.

Can someone suggest some free software to make such maps? Thank you.CountMacula (talk) 13:22, 11 January 2015 (UTC)

I'm not aware of any (free) software as simple/user-friendly as what you describe. However, InkScape is free and certainly capable of producing such a map. There is a tutorial at the top of this talk page. If you post a request with the data table and article name of the request page, one of us could easily build it for you. The map used as a source needs to be freely licensed, but that is not a problem.Gaff (talk) 19:12, 11 January 2015 (UTC)
Thanks, Gaff! I'll look into Inkscape and try to do it myself. But the font of the cartography tutorial is so small, I can barely read it.CountMacula (talk) 20:05, 11 January 2015 (UTC)
There is a (if you ask me) much more elegant way of doing it using the advantages of svg images. Svg images can be edited by inkscape, but if you simply (really, I had no idea until 2 years ago or so) open the svg file in a text editor (right mouse click; open with .... then choose a text editor) you can also really edit the text. There are a lot of maps that have been prepared to accept colouring by just typing the ISO 3166 country code. It is simply
  • a list like .be, .nl, .us (to colour Belgium, Netherlands and the US; note that there is a point (.) before the country, and a comma (,) between them)
  • followed by a colour statement
    • {
    • opacity: 1;
    • fill: orange; [ or to use a hexadecimal colour: you can say fill : #337700; ]
    • }
An example can be found at File:Arms_Trade_Treaty_status.svg, which you can use as a "scaffold". Just browse down ca 40 lines until you find "/* List of states which have ratified or acceded (green) */" and then start filling in countries.
  • just save as an .svg file
  • and upload it
The advantage is that you can be much more exact in colouring, and also take the info easily to an other map, if the world map changes (again...)... L.tak (talk) 20:15, 11 January 2015 (UTC)
That looks like a fine way to do it, L.tak. I believe I will. TYVM!CountMacula (talk) 09:21, 12 January 2015 (UTC)

QGIS to SVG[edit]

I'm hoping to get my hands on the IUCN Red List range data for all lemur species so that I can update the existing range maps. I'm as green as you can possibly get with QGIS. Just by tinkering with it last night, I managed to learn that all I needed was to obtain SHP files (in the public domain) for Madagascar, the Comoros, and the major rivers (global) and add them along with the IUCN Red List SHP file to a new project—the software automatically puts everything in the right place. I figured out to tweak settings and several other things, and now I just need to export this work to a SVG so that I can polish it off in Inkscape. I found this tutorial, but I'm having a hard time scaling the map in Composer before exporting to SVG. After I choose the option to "Add a new map" and draw the box on the page, the map of Madagascar isn't centered and I can't find a way to center it. Often the Comoros get cut off. I can change the scale (which is hard given that the value is in the millions) but then it often includes unwanted material, like the rivers of Africa. I just can't find an easy way to constrain the map to just the part of the map I want. After that, I can figure everything else out in Inkscape. Any advice? I don't mind corresponding via email if it helps to share files and/or screenshots. – Maky « talk » 09:01, 14 January 2015 (UTC)

No tips on QGIS? Sorry, but after figuring out 90% of it, I just need help with this last little bit so I can quickly process hundreds of data sets. – Maky « talk » 05:55, 21 January 2015 (UTC)
Through help on a IRC channel and trial and error, I have figured all of this out. If anyone needs help with the basics of QGIS, just ask. – Maky « talk » 11:54, 30 January 2015 (UTC)

Checkerboard backgrounds[edit]

This is a basic how to use InkScape question, but how can I get rid of the checkerboard background on my maps? Some have them and some don't when viewed in the media viewer. They look fine in the infoboxes. This one is the current map of concern File:Toxostoma longirostre species distribution map.svg. Thanks --Gaff (talk) 03:40, 29 January 2015 (UTC)

No chequers
@Gaff: It's not Inkscape, or the way that you draw them. It's the way that partially-transparent SVG files are always drawn on the file description pages. It's there partly to show the maximum extent of an image that might otherwise have no clear boundaries; but it's also there to indicate which portions are unpainted, and therefore transparent. See for example File:First angle projection symbol.svg where I deliberately gave the whole image a white background; compare File:BSicon exLKDSTa.svg which has two colours (pink and white), but no background so that the parts outside the circles are transparent. This transparency is intentional, and means that the image can be overlaid on another, as I did at Template:Mid-Suffolk Light Railway (look for the row marked "Proposed Debenham station" where it is overlaid on File:BSicon exKDSTe.svg).
The chequered background is not shown when the image is used in the normal way (see right), but only when you are on the file description page. If you're on Commons, it's always there; but in English Wikipedia, it only shows when you hover your mouse over the image - move it away, and the chequered background disappears. Try File:BSicon exLKDSTa.svg (on English Wikipedia) again, and compare c:File:BSicon exLKDSTa.svg which is the same page on Commons. --Redrose64 (talk) 11:18, 29 January 2015 (UTC)

SVG to bitmap[edit]

A week ago, Giovannibeltran67 made two requests on the project page, asking for maps to be updated to show the status of same-sex marriage in Chile and Finland. The Chile request appears premature, as we have no evidence that the Chilean president has yet ratified the bill into law. I could easily fulfill the Finland request, but only by converting the current SVG to a PNG or GIF, updating it, and uploading it as a new file. I lack the skill to modify the SVG directly. I could edit the SVG if it had comments like <!-- This section is for Finland -->, but it doesn't.

So, should I go ahead and upload an up-to-date PNG or GIF? Or should forget about it and hope that someone skilled in handling SVGs comes along? Maproom (talk) 22:11, 8 February 2015 (UTC)

The SSM maps are updated frequently, as various countries and U.S. states pass laws permitting the practice. Updates for these maps are usually proposed on their talk pages on en.wp (not Commons, even though the actual images are on Commons); for example, File:Same sex marriage map Europe detailed.svg, which I have updated myself, is discussed at File talk:Same sex marriage map Europe detailed.svg. Updating a SVG is quite easy, use a plain text editor, find the shape and alter its fill colour - for example, when I updated Gibraltar at 17:16, 1 April 2014, I changed one instance of fill="#CCCCCC" to fill="#0066FF". You can also use an application like Inkscape or Adobe Illustrator, but those tend to bloat the file with metadata (and can damage certain constructs). Altering SVG maps to a raster format (whether PNG or something else) makes reverse conversion extremely difficult. --Redrose64 (talk) 22:53, 8 February 2015 (UTC)
I will take your advice, and do nothing. To "find the shape" is not easy for me, when there are over 1,000 unlabelled paths in the SVG. Maproom (talk) 23:43, 8 February 2015 (UTC)

Replacing range map with more than 10 species[edit]

I am working to create a new range map for sportive lemurs, replacing the problematic File:Lepilemur distribution.svg that is currently used. This image appears to be a copyright violation, lifted from a 2006 publication. I have recently created a new range map template for endemic Madagascar flora and fauna (File:Madagascar range map template.svg—open to comments), which I created using both QGIS and Inkscape. (An example map created from this template is File:Phaner_range_map.svg.)

I have the SHP files from the IUCN for all sportive lemurs and can make a better map, but there are over 20 species. Looking at Color Brewer 2.0, the source for our color recommendations, the website suggests colors for up to 12 data sets for qualitative data, but no more. I was wondering if anyone had advice on colors or whether the map should be made at all. – Maky « talk » 20:13, 12 March 2015 (UTC)

My recommendation would be to split them into two maps, do 13 species on each map, that lets you re-use colors and the results should be easier to read. Kmusser (talk) 13:41, 13 March 2015 (UTC)
Thanks for the reply and suggestion. I did exactly that at the article True lemur. However, there are occasional overlaps, and I haven't figured out an ideal way of handling them. (See either of the two maps on that page as examples.) What would you suggest? – Maky « talk » 16:53, 13 March 2015 (UTC)
Ideally the overlapped area would be striped with the two overlapping colors, not sure how to do that in SVG though. Another possibility would be giving the color layers a bit of transparency. Kmusser (talk) 17:11, 13 March 2015 (UTC)
Stripes in SVG isn't difficult, see the shapes for Croatia and Hungary at File:Same sex marriage map Europe detailed.svg. --Redrose64 (talk) 17:51, 13 March 2015 (UTC)
Thanks. I've already played with stripes and transparency. Transparency with two or three slightly overlapping colors was hard to interpret, and stripes didn't work because I kept the areas on separate layers. I guess I'd have to put them on the same layer and do an exclusion or division... or something... and then fill the overlap area with a pattern. The problem is that up to 3 species may overlap the same area very slightly. If you want to experiment with the overlap with orange, blue, and red on this map, you're welcome to. – Maky « talk » 20:27, 13 March 2015 (UTC)
Maybe try making the overlapping area its own little polygon on its own layer? Kmusser (talk) 14:17, 16 March 2015 (UTC)

A how-to request for OpenStreetMap[edit]

A technical question about OSM: I want to make a Location map template for a city (Ljubljana, to be precise) from a screenshot in OSM. Is there an easy way to figure out border coordinates from the browser's interface or must I do it by centering features on all sides and reading their X/Y coordinates? Or maybe there's a more comprehensive way to export the current view in vector format from which those coordinates are evident? Any pointers would be much appreciated. — Yerpo Eh? 09:32, 19 July 2015 (UTC)

  • The OSM export function will show you the coordinates of the bounding box you download, which can then be used as the data for the associated location map origin.  Philg88 talk 10:04, 19 July 2015 (UTC)
Whoa, I didn't even know that existed, thanks. And sorry if a stupid question, but is there any easy way to convert the resulting XML file to a decently-sized (i.e. not huge) SVG? — Yerpo Eh? 10:20, 19 July 2015 (UTC)
