This article's title, Guyou hemisphere in a square projecction, sounded as if it was about something called a Guyou hemisphere that was in something called a square projection. After reading a bit, I realized that was not what was meant. That's why I added the hyphens. Yet another case of how hyphens can be magnificently efficient in conveying information, and why it is to be regretted that their use is often no longer taught.

File:Guyou doubly periodic projection SW.JPG to appear as POTD

Hello! This is a note to let the editors of this article know that File:Guyou doubly periodic projection SW.JPG will be appearing as picture of the day on December 4, 2014. You can view and edit the POTD blurb at Template:POTD/2014-12-04. If this article needs any attention or maintenance, it would be preferable if that could be done before its appearance on the Main Page.

Picture of the day

The Guyou hemisphere-in-a-square projection is a map projection used to project a hemisphere. It is conformal everywhere except for the four corners of each hemisphere's square. This projection, developed by Émile Guyou in 1887, can be considered an oblique aspect of the Peirce quincuncial projection, with which it has numerous similarities.

The imagery used for the map is a derivative of NASA's Blue Marble summer months composite, with oceans lightened to enhance legibility and contrast.Map: Strebe, using Geocart
