[edit] Map projections image files
I am not sure whether I am right on this one, but these images seem identical with ESRI's poster on map projections that comes with their book "Getting to know ArcGIS". Someone should verify the copyright of these images. The USGS website does not mention any copyright information.
[edit] Map projections from Planet math
I don't know if the articles for projections exist, but it might be worth nabbing those that do from Planet math. Mr. Jones 15:05, 8 May 2004 (UTC)
[edit] Formatting criticism
You should put a ":" before the math marker of the Mercator formula, to indent it. Same with the next line starting with phi. -- Martin Vermeer
- Okay, go ahead cleaning it up :-)
[edit] History of Map Projections
12/29/05
It would be a good idea to add a short section on the history of Map Projections - this is an interesting topic, as it mirrors the evolution of human knowledge over the centuries. Great ingenuity has gone into developing the ideas of map projection to make it more and more useful for navigators and other users.
[edit] Benson Projection
I have invented a superior map. Everyone will agree that it is the best. How do I submit it? 70.177.90.238 20:40, 11 January 2006 (UTC)
- You don't. If you want, tell people about it, and perhaps one of them will add information about it to the article. See Wikipedia:Autobiography. ¦ Reisio 21:33, 11 January 2006 (UTC)
[edit] map projection or spherical projection?
IMHO spherical projection is the more standard mathematical term for this. i've done a redirect from spherical projection to this article, but if noone objects, then i would suggest switching the redirect to the other direction - i.e. "spherical projection" would be the main article.

- But the main use is cartographical. Mathematicians may have a few projections they use frequently and then generalise. But cartographers use all these and more. --Henrygb 09:05, 27 April 2006 (UTC)
- Also note that that the surface to be projected in Cartography is not always a sphere, it might be a spheroid (or ellipsoid). On the other hand, the projection process is not necessarily geometric - From the article: "The term "projection" here refers to any function defined on the earth's surface and with values on the plane, and not necessarily a geometric projection."

[edit] European or American map
The article uses maps with America at the centre. I though that the Wikipedia standard was to use maps with Europe/Africa at the centre (because they don't cut Asia in half). If so, does this article deviate from that for a specific reason? And are there names for these maps (I can't find an article on it)? DirkvdM 07:06, 17 August 2006 (UTC)
- Most of the maps come from the United States Geological Survey. --Henrygb 09:14, 17 August 2006 (UTC)
[edit] Triangular map?
A while back I heard of a type of projection that was made up of a bunch of triangles, and that by unfolding it a certain way, it showed the world as a chain of continents surrounded by water, or a chain of oceans surrounded by land. Does anyone have any information on this? Stale Fries 00:13, 3 March 2007 (UTC)
- Nevermind, it's Dymaxion map. Stale Fries 00:16, 3 March 2007 (UTC)
