# Talk:Plate carrée projection

I wonder if there is not a subtil difference between the names:

"plate carrée projection or equidistant cylindrical projection or geographic projection or equirectangular projection"


For me "equidistant cylindrical projection" should be more general than "equirectangular projection" and "geographic projection" more particular than "equirectangular projection". see: from mathworld

Concerning "geographic projection" I wonder if it is not the case where: ${\displaystyle \lambda _{0}=0}$

## plate carrés vs equidistant cylindrical

The Plate carrée (the full French designation is Cartes Plates Carrés) projection is a special case of the more general equidistant cylindical projection, where the standard parallel is the Equator and the geographical graticule is square. The corresponding French name is Cartes Plates Parallelogrammatiques. Equidistant cylindical projection and equirectangular projection are synonyms, all refering to the general case with two (symetrical) standard parallels and a rectangular graticule. I suggest the article to be slightly modified accordingly. Regards,Alvesgaspar 14:26, 26 April 2006 (UTC)

So, the suggested merging should be, if accepted, the other way around... Alvesgaspar 17:25, 7 August 2006 (UTC)

Letting power run to my head, I have, with no permission whatsoever, merged this article into equirectangular projection, and left this one as a simple redirect. It was the right thing to do. mdf 16:08, 18 October 2006 (UTC)
