Replace low-contrast images

[edit]
Sample of new image style

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. Strebe (talk) 22:41, 6 August 2011 (UTC)[reply]

Excellent work!!! I applaud your efforts, and I wish you the best in everything you do! Deejaye6 (talk) 06:47, 14 November 2011 (UTC)[reply]

Why Doesn't Wikipedia Use This Map??

[edit]

I've noticed an annoying habit of Wikipedia to use the outdated Robinson map that's just as inaccurate as the old Mercator map (one expands one region (laterally) while shrinking the others, the other shrinks one region while expanding the others). The Kavrayskiy VII projection is the most accurate rectangular projection I've ever seen and is laterally equivalent throughout! What a novel concept!

Is there any way to start a movement toward changing this to the standard? Deejaye6 (talk) 06:51, 14 November 2011 (UTC)[reply]

Kavrayskiy VII looks as excelent projection to be used by Wikipedia to all general whole-world. Because maps are often uploaded by inexpirienced users, who doesn't really know much about projections, it is good idea to teach them and note to use some good projection mapping, like Winkle triple or Kavrayskiy VII (there are probably even better ones, but they are rather obscure and often you will not find them in your popular mapping program). I think it is also good idea to promote this projections on other projects, like OpenStreetMap or Google Maps (at least at whole-world level). --91.213.255.7 (talk) 13:20, 17 November 2011 (UTC)[reply]

Hello! This is a note to let the editors of this article know that File:Kavraiskiy VII projection SW.jpg will be appearing as picture of the day on July 21, 2015. You can view and edit the POTD blurb at Template:POTD/2015-07-21. 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! — Chris Woodrich (talk) 00:17, 2 July 2015 (UTC)[reply]

Kavrayskiy VII projection
The Kavrayskiy VII projection is a map projection invented by Vladimir V. Kavrayskiy in 1939 as a general purpose pseudocylindrical projection. It produces maps with low overall distortion, despite its straight, evenly-spaced parallels and a simple formulation.Map: Strebe, using Geocart
Looks fine to me. Thanks, Chris Woodrich. Strebe (talk) 19:41, 3 July 2015 (UTC)[reply]

"Chinese polyconic projection"

[edit]

I deleted an edit by User:146.96.252.3 that mention a "Chinese polyconic projection". See discussion I have opened up here. Strebe (talk) 18:38, 15 July 2017 (UTC)[reply]
