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:

Very cool. Mars comes in to focus. Thanks for posting these.
Does the shape of Mars and the variety of mapping conventions that have been used over the years cause problems with geographic features appearing to shift from one mission to the next? (Obviously, it's not the geographic features shifting, just the coordinate systems we use to represent them...) --Emily -------------------- My website - My Patreon - @elakdawalla on Twitter - Please support unmannedspaceflight.com by donating here.

Does the shape of Mars and the variety of mapping conventions that have been used over the years cause problems with geographic features appearing to shift from one mission to the next? The main problem other than registration errors has been the various redefinitions of W0 and to a lesser extent, the IAU spheroid. See http://astrogeology.usgs.gov/Teams/Geomati...esy/P22D-06.pdf Hopefully we are now past these problems, at least at the 100-meter scale. -------------------- Disclaimer: This post is based on public information only.
