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:

here's an interesting comparison if anyone's interested. It's a comparison of global cylindrical (that is, simple cylindrical, or equirectangular) projection maps of Mars from Mariner 9, Viking and MGS. The Mariner 9 one is the 1975 USGS map, reprojected into Simple Cylindrical. Viking is the global mosaic made by USGS. MGS is a composite of TES albedo mapping and the MOC wide angle geodesy mosaic, both with artifacts removed. Some problems remain in all of them, but you do get to see significant changes in the pattern of albedo markings. We tend to forget about them now, being so focussed on boulders and layering. It would be possible to make maps like these for every opposition since about 1840 - that would make an amazing animation!

I have a set going back to I think the 1890s...If I can find it I will post it (that is a big if).
