Replace low-contrast images
I will be replacing images on the various map projection pages. Presently many are on a satellite composite image from NASA that, while realistic, poorly demonstrates the projections because of dark color and low contrast. I have created a stylization of the same data with much brighter water areas and a light graticule to contrast. See the thumbnail of the example from another article. Some images on some pages are acceptable but differ stylistically from most articles; I will replace these also.
The images will be high resolution and antialiased, with 15° graticules for world projections, red, translucent equator, red tropics, and blue polar circles.
File:Sinusoidal projection SW.jpg to appear as POTD
Hello! This is a note to let the editors of this article know that File:Sinusoidal projection SW.jpg will be appearing as picture of the day on March 22, 2015. You can view and edit the POTD blurb at Template:POTD/2015-03-22. If this article needs any attention or maintenance, it would be preferable if that could be done before its appearance on the Main Page. Thanks! — Crisco 1492 (talk) 01:05, 4 March 2015 (UTC)

The sinusoidal projection is a pseudocylindrical equal-area map projection. Used as early as the 16th century, this projection shows distances accurately along the central meridian and the equator; areas furthest from these lines are the most distorted.
What is the advantage?
I can get from the caption of a picture that sinusoidal projection represents area correctly, but it's not mentioned in the article at all, at least not that I could read. I'm not sure how to work it in (I'm not a cartographer), but it should be up front, preferably the first paragraph. Nerfer (talk) 14:23, 23 March 2015 (UTC)
