I have recently freaked out a little bit about Martian maps of all sorts. And finally I was astonished with those highly detailed beauties that I list below. Nonetheless. some of them have huge inconsistencies (crater names) easily noticed when we compare the surroundings of Gusev crater. Enjoy:

I like the second USGS map.
[attachment=5804:attachment] Nice hill shading, nice subtle colors, not the usual fully-saturated acid-trip color schemes you see in a lot of NASA images. My one criticism is that the hypsometric color pallette should go from dark to light monotonically with altitude. It's a little confusing that you go from light brown to dark brown and back to light brown again as you head up the Tharsis rise. Things to keep in mind when making your own maps. Here are two wonderful sites about map making, full of good ideas and wise advice: The National Park Service: Shaded Relief History and techniques: Relief Shading. Explore this site, check out the section on Cartographers and examples of their work. What a fascinating art. For example, look at this amazing projection of a map of Europe designed by Heinrich Berann: [attachment=5805:attachment] (By the way, to yank pictures out of the annoying pdf files, you can use PDFExtractTiff by verypdf.com) |

Hi Don,
Mapping is an ancient art, and I'm a great fan of relief shading (my Dad's ancient cloth map of the UK's Lake District is a joy to behold). It's a shame that the technique's fallen out of popularity. AndyG |
