To do[edit]

edit·history·watch·refresh Stock post message.svg To-do list for Wikipedia:WikiProject Geographical coordinates:

Find coordinates for[edit]

Use Maybe-Checker: verify and/or add coordinates to articles in categories likely to need coordinates.

Articles are also listed on WolterBot's cleanup listings (User:WolterBot/Cleanup statistics)

See also: Wikipedia:Obtaining geographic coordinates

Tag articles needing coordinates[edit]

{{coord missing|country name}} is added to articles needing coordinates. This makes them available for the previous step.

    • Identify special formats not yet converted, e.g. E12 23 54 N23 34 52
  • Clean up / reduce redundancy in U.S. city articles (rambot/smackbot generated), see past discussion
  • Suggestions for extensions at mw:Summer of Code 2009#MediaWiki core and new extensions
  • Discuss, summarise and specify a set of changes to geohack, such as type list revision, support for linear features, bug fixes, &c

Seeking coordinates advice[edit]

I asked this question in Teahouse and was directed here. This article is catted as needing coordinates. It is about an outbreak of wildfires across two states. It refers to locations using city and county names which are all linked. Looking for advice as to how to approach.

  • Do nothing except remove the {{coord missing}}, since each of the linked cities and counties has its own coordinates
  • Add title coordinates that approximate the center of ALL the fires with a low precision per WP:OPCOORD
  • Add coordinates to this article for each of the named cities and counties (specifically where and in what form?)
  • Research to try to establish more specific burn areas for each fire, estimate the center of each burn area, and add the resulting coordinates (ugh)
  • Something else

Thanks! Mandruss (talk) 22:39, 15 July 2014 (UTC)

Usage guidelines say coordinates are for "events that are associated with a single location" (that is "more or less fixed in one place"). Since the article refers to multiple events over a widespread area, I don't think coordinates are really necessary. Cheers, SpencerT♦C 01:32, 16 July 2014 (UTC)


We need a new template (like template:Coord/Wikidata) which give its parameter from Wikidata, d:Property:P625. Thank you.--Çalak (talk) 11:55, 30 July 2014 (UTC)

We certainly need to migrate our activities to Wikidata and internationalize the geocoding work across Wikipedia editions, and automatically pulling coordinates from Wikidata will be an essential part of it. How exactly to go about this while maintaining forward and backward compatibility, preserving, and preventing loops in, data provenance, and detecting interference from vandalism on Wikidata, is a complex problem. One possibility would be to add this capability to {{coord}} itself. Whichever way we do it, it's going to be tricky, and will need a lot of thought. -- The Anome (talk) 23:25, 20 September 2014 (UTC)
Since Çalak's comment, {{Coord}} has been updated to fetch values form Wikidata. The documentation was updated in this edit. However, AFAICT, only latitude and longitude are fetched, not |region=, nor |type=. These still need to be set locally, according to this discussion.

Articles for each meridian/parallel[edit]

Are these really necessary? All they have is a list of cities that pass through them, so they don't seem to have much useful information. (except, of course, the Prime Meridian and Equator, Tropic of Cancer, etc.) See Template:Geographical coordinates for the whole list of lat/long articles.

Maybe all the minor articles could be merged into a "Lines of Latitude" and "Lines of Longitude" article, with a table with famous cities that pass through each line. Llightex (talk) 21:38, 2 September 2014 (UTC)

Most of the edits were made by Bazonka (talk · contribs), so sending a notification. --Redrose64 (talk) 23:08, 2 September 2014 (UTC)
I don't know which articles you've been looking at Llightex, but none of them only list cities. They contain lists of countries, territories, seas, and oceans through which the lines pass - much more information than just cities. Anyway, who are we to define what is and isn't useful to the readers of Wikipedia? The rule for inclusion in Wikipedia is notability, not usefulness. Some of these latitude/longitude articles have been raised at AFD before, and they have all sailed through as Keep due to their notability. Feel free to raise them again, but you will probably get the same outcome. Your suggestion about combining them all into one article would result in something that is extremely long, because of course, they don't just list cities. Bazonka (talk) 06:56, 3 September 2014 (UTC)
Yes, they are necessary. Andy Mabbett (Pigsonthewing); Talk to Andy; Andy's edits 12:36, 21 September 2014 (UTC)

Comment on the WikiProject X proposal[edit]

Hello there! As you may already know, most WikiProjects here on Wikipedia struggle to stay active after they've been founded. I believe there is a lot of potential for WikiProjects to facilitate collaboration across subject areas, so I have submitted a grant proposal with the Wikimedia Foundation for the "WikiProject X" project. WikiProject X will study what makes WikiProjects succeed in retaining editors and then design a prototype WikiProject system that will recruit contributors to WikiProjects and help them run effectively. Please review the proposal here and leave feedback. If you have any questions, you can ask on the proposal page or leave a message on my talk page. Thank you for your time! (Also, sorry about the posting mistake earlier. If someone already moved my message to the talk page, feel free to remove this posting.) Harej (talk) 22:47, 1 October 2014 (UTC)

Improved progress[edit]

This new and, I hope, exciting graph shows the apparent recent improvement in progress as of September/October 2014, after a recent period of having settled down to just keeping pace with Wikipedia's growth (although that itself is a significant achievement, given the vastness of Wikipedia and its rapid growth rate). The new trend seems to be have kept steady for two months, so I suspect this is a real trend, not just data fluctuation.

If (entirely hypothetically) this rate of straight-line improvement were to be kept up indefinitely, we would hit 100% somewhere in 2021-2022. Whether the apparent improvement in the rate of progress can be sustained (I would expect something more like a logistic curve in practice), and whether it was caused by the start of transwiki copying from Wikidata, is an interesting question -- The Anome (talk) 14:06, 19 October 2014 (UTC)

Category:Iran articles missing geocoordinate data[edit]

There are currently over 13,000 articles outstanding in Category:Iran articles missing geocoordinate data. It would be a big win if we could geocode these. Does anyone have access to either better machine-readable coordinates than are stored in GNIS, or (perhaps) a better approach to string-matching Arabic place-names than mere string comparison?

In addition, since I don't speak Farsi and thus can't do it myself, is anyone here an editor on fawiki, or a Farsi speaker willing to work with me on somehow cross-connecting geocoding efforts between the two projects? A look at the Google translation of fa:ویکی‌پدیا:ویکی‌پروژه_مختصات‌دهی seems to show that there is a local community already there working on the problem. -- The Anome (talk) 14:35, 19 October 2014 (UTC)

Some or all of these may have occurred to you; but in case not:

Hi -- I've successfully imported everything I can from Wikidata, with quite a lot of success, but I've exhausted that source for the time being. Using OpenStreetMap data sounds really interesting, but I don't yet know how to get a sufficiently filtered OpenStreetMap dump that will allow me to download just place coordinates, instead of the full geodata for the entire map: I just haven't got the resources to wade through terabytes of map data to find what I need. The WikiProject and embassies sound like a good idea -- why didn't I think of that?
Also, a huge number of these Iranian-place articles seem to have been autogenerated using (among other things) Iranian state-published census data, but I don't know of any matching coordinates file that cross-correlates to the gazetter data set. If there were, and surely they must have them somewhere, this would be a trivial task. -- The Anome (talk) 21:27, 19 October 2014 (UTC)
Update: I've just posted to Wikipedia talk:WikiProject Iran asking for help on this. -- The Anome (talk) 23:43, 19 October 2014 (UTC)
