mid-height dot[edit]

May I just say that the use of a mid-height dot for the decimal point was traditionally taught in British schools. It preserves the distinction between the decimal point and the full stop, a distinction which helps when a decimal number occurs at the end of a sentence. I would certainly raise the decimal points in handwritten work. The use of the same symbol for both is laziness in English although normal in, say, German. Furthermore, the distinction of phi and varphi is a matter of taste, not of substance. I simply preferred to use phi in my major rewrite of this article since I find varphi rather inelegant. Neither of these edits added to the content of the article but I shall not trouble to undo them. Peter Mercator (talk) 16:33, 25 June 2011 (UTC)

The use of the middot as a decimal point fails to preserve the distinction between that and the other frequent use of the middot for multiplication. Michael Hardy (talk) 16:47, 25 June 2011 (UTC)

I've raised this issue more publicly[edit]

re: Draft for flattening[edit]

Hi, Peter Mercator. I noticed that your draft article was showing up in Category:Geophysics, among other categories. It shouldn't (see WP:USERNOCAT), so I put a colon in front of each category to suppress the listing. You can undo this when you are ready to promote the article to mainspace. RockMagnetist (talk) 21:52, 10 January 2012 (UTC)

I notice that your other drafts have the same problem. Could you fix them please? RockMagnetist (talk) 21:54, 10 January 2012 (UTC)

Sorted, I hope. Peter Mercator (talk) 21:58, 10 January 2012 (UTC)
Well, at least the flattening one is sorted. I have never added a geophysics category to any article. I think they were all there when I copy pasted the articles into my user space as drafts. Happy if you take action on the various main pages.   Peter Mercator (talk) 22:03, 10 January 2012 (UTC)
Sorry, I have now read WP:USERNOCAT and I will take action on present pages and be more careful in the furture!  Peter Mercator (talk) 22:10, 10 January 2012 (UTC)
Thanks. I have been guilty of the same mistake! RockMagnetist (talk) 22:24, 10 January 2012 (UTC)

Gnomic --> Mercator[edit]

Hello Peter, My compliments for your Mercator article. At the moment I'm working on an article about great-circle navigation on the Dutch WP: Grootcirkelnavigatie. For that I was lookong on Commons for something that compares to this picture (from Bowditch). The closest is your drawing File:Equirectangular with rhumb+circle+triangle.svg. Are you able to produce a drawing like my example, or otherwise, can you tell me what software you used? Regards, BoH (talk) 15:17, 13 January 2012 (UTC)

Thanks for your compliment: I haven't had the courage to replace the present article on Mercator with this draft. I produce my figures using the free software Inkscape and they are easily modified. They are schematic in the sense that I did not plot accurate curves: for that I would have use the gnuplot package which is also free but more difficult to use. However I am not sure what you are trying to do. If you simply want to use the Bowditch drawings you could upload them to commons as they stand. Do you want both drawings or just the Mercator one? I could possibly do both if I had the data points shown on the Bowditch maps. Do you want an example from the Pacific or the Atlantic. Come back with more details.  Peter Mercator (talk) 18:03, 13 January 2012 (UTC)
I use Inkscape myself, so I will see if I can download gnuplot and have a go at it myself.
And please do not hesitate; I think it would be a loss for Wikipedia if you did not replace the current article!
Thanks! BoH (talk) 12:55, 14 January 2012 (UTC)

Disambiguation link notification for April 4[edit]

Hi. When you recently edited Mercator 1569 world map, you added links pointing to the disambiguation pages Diego Gutierrez and Edward Wright (check to confirm | fix with Dab solver). Such links are almost always unintended, since a disambiguation page is merely a list of "Did you mean..." article titles. Read the FAQ • Join us at the DPL WikiProject.

Hi[edit]

Hi, I am amazed by the work you are doing in the article on the Mercator 1569 map. I have a passion for old maps too (see [1]) and hope we can collaborate in the future. I may be of help in adapting your article to Wikipedia:Manual of Style and to the conventions and policies of Wikipedia and general, if you wish. Best, --Hispalois (talk) 06:35, 28 April 2012 (UTC)

Excellent contributions[edit]

As a spin-off from other activities I have recently had to acquaint myself with some topics from geodesy such as the geodesic problem on reference ellipsoids such as WGS 84. I have noticed some of the brush-ups you have made to the articles within this subject area. Especially with new high quality figures and illustrations. The are very educational and concise with good notation and nice consistent graphics. I just wanted to say thanks for your efforts, and that it is appreciated. I enjoy making good figures myself, but also find it very time-consuming, and I am not yet retired :-) I have reused some of your figures (with proper attribution and licensing of course) on a corporate wiki for illustrating some aspects about how to convert distances to geographic points on the surface of the earth and for illustrating the basic geometrical concepts in these operations, like the auxiliary sphere, reduced latitude, geographical latitude, etc.... the figures say more than many words. Thanks again. --Slaunger (talk) 13:43, 31 August 2012 (UTC)

I see above that they have been created using InkScape. Also my preferred tool for such kinds of figures, and the svg files are easy to tweak for other purposes in derivative works. --Slaunger (talk) 13:46, 31 August 2012 (UTC)

Material for you, urgent[edit]

I have something on Mercator and portolans here and the famous Mercator letter linked with 1569 map here. I just completed my portolan pages. Unfortunately today the discussion started to delete them all. Better you save what you need. Who can help? -- Portolanero (talk) 20:10, 18 February 2013 (UTC)

Notice of Dispute resolution discussion[edit]

Peacedove.svg

Hello. This message is being sent to inform you that there is currently a discussion at Wikipedia:Dispute resolution noticeboard regarding a content dispute in which you may have been involved. Content disputes can hold up article development, therefore we are requesting your participation to help find a resolution.

Guide for participants

If you wish to open a DR/N filing, click the "Request dispute resolution" button below this guide or go to Wikipedia:Dispute resolution noticeboard/request for an easy to follow, step by step request form.

What this noticeboard is:
  • It is an early step to resolve content disputes after talk page discussions have stalled. If it's something we can't help you with, or is too complex to resolve here, our volunteers will point you in the right direction.
What this noticeboard is not:
  • It is not a place to deal with the behavior of other editors. We deal with disputes about article content, not disputes about user conduct.
  • It is not a place to discuss disputes that are already under discussion at other dispute resolution forums.
  • It is not a substitute for the talk pages: the dispute must have been discussed extensively on a talk page (not just through edit summaries) before resorting to DRN.
  • It is not a court with judges or arbitrators that issue binding decisions: we focus on resolving disputes through consensus, compromise, and explanation of policy.
Things to remember:
  • Discussions should be civil, calm, concise, neutral, and objective. Comment only about the article's content, not the other editors. Participants who go off-topic or become uncivil may be asked to leave the discussion.
  • Let the other editors know about the discussion by posting {{subst:drn-notice}} on their user talk page.
  • Sign and date your posts with four tildes "~~~~".
  • If you ever need any help, ask one of our volunteers, who will help you as best as they can. You may also wish to read through the FAQ page located here and on the DR/N talkpage.

Please take a moment to review the simple guide and join the discussion. Thank you!

Speedy deletion nomination of Franciscus Monachus[edit]

Hello Peter Mercator,

I wanted to let you know that I just tagged Franciscus Monachus for deletion, because it seems to be inappropriate for a variety of reasons.

If you feel that the article shouldn't be deleted and want more time to work on it, you can contest this deletion, but please don't remove the speedy deletion tag from the top.

You can leave a note on my talk page if you have questions. Jo-Jo Eumerus (talk, contributions) 10:52, 19 January 2016 (UTC)

  • Because people often start an article and then abandon it, and because we do not want readers of the encyclopedia to come upon empty or "watch this space" pages, articles with no content may be speedily deleted. As this one looks as though it's going somewhere, I have instead "userfied" it - moved it to User:Peter Mercator/Franciscus Monachus where you can work on it. When it is ready, you can either click the blue "Submit" button to send it for review to WP:Articles for creation, or move it directly to the main encyclopedia. In the latter case, you will need to remove the <!-- --> comment tags I have put around the categories.

I had rather hoped that I had left enough as a stub to encourage someone else to work it up! I am very busy with a major rewrite of Gerardus Mercator where I have already linked to Monachus!
Peter Mercator (talk) 11:54, 19 January 2016 (UTC)
There was no text there at all - nothing but the stub template and the categories! You need to give others something to get their teeth into. The new one is fine from that point of view. I have deleted the userfied stub as no longer required. JohnCD (talk) 20:11, 19 January 2016 (UTC)

Gerardus Mercator Images[edit]

Hello, It has come to my attention that you are writing an article on the subject of Gerardus Mercator. As two images regarding Gerardus Mercator have recently been uploaded to Wikimedia Commons by a colleague of mine during a recent History of Medicine Wikipedia editathon at the University of Edinburgh on 16-18th February 2016, I thought I should bring them to your attention, in case they are of any use. The weblinks are here:

Best regards, Stinglehammer (talk) 11:35, 2 March 2016 (UTC)

  • Many thanks for the image links. As yet I haven't got round to adding images but I must do so as soon as the text matures. I'm in Edinburgh.  Peter Mercator (talk) 11:49, 2 March 2016 (UTC)

Curation of old maps in Commons[edit]

Hello

I am happy to see that you keep on contributing so productively to articles on cartography in Wikipedia.

I was thinking that the increasingly vast collection of old map images in Commons needs curation, so when I saw an idea contest organized by the Wikimedia Foundation I put together a proposal to do it (link). I would very much appreciate if you could take a look at it and let me know what you think, either on the discussion section or privately if you prefer.

Thanks, --Hispalois (talk) 20:57, 11 March 2016 (UTC)

Good luck on your project for Commons is indeed a mess. My gut feeling is that everything is over-categorised and I'm not sure that more categories is the best solution. For example I'm busy with Mercator at the moment and I think it would be a thankless (foolish?) task to assign all his old maps to all the different locative sub-categories of AOMC. There is so much wrong with Commons: creation and editing is really clunky, the structure is anarchic, the search mechanism is poor and so on. I tried searching under Mercator for the category Mercator 1569 world map (which I created) and I'm still looking. Sorry to be so negative; perhaps it's a grumpy old man day. Peter Mercator (talk) 13:46, 13 March 2016 (UTC)
