message: Did Robinson ever specify what interpolation formula should be used?  The article doesn't seem to address the question.  The obvious linear interpolation is tempting, but it would cause the edge of the map to be polygonal....Smjg 15:48, 23 January 2006 (UTC)
replies: text: Robinson didn't use an interpolation formula. There's an article in the April 2004 issue of the Cartography and Geographic Information Science journal with further explanation and a numerical approximation of the interpolation. bennylope (talk) 15:29, 17 July 2009 (UTC)

message: Does anyone know the math that is involved in making a Robinson projection map? I'm looking to use it for a map, but I can't find any explanations... 87.196.55.187 13:18, 20 June 2006 (UTC)

message: 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.
Please discuss agreement or objections over here (not this page). I intend to start these replacements on 13 August. Thank you.
