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 true, Doug. The top image was produced in a very different way. While the other two are spacecraft data, albeit manipulated, the top one is a drawing. It exaggerates small details more than the other two, and is more contrasty. My intention is to show surface changes, and it does do that well - look around Isidis and Elysium, or north of Tharsis, especially.
Actually I had another reason for making these. I'm preparing a set of maps to serve as base maps for my Mars atlas. As I go through the history of Mars exploration the base map I use will evolve to follow the growth of our knowledge, and then the changing appearance of the planet. Step 1 is the old ACIC map, pre-Mariner 4, with canals. They have to be converted to Simple Cylindrical so my software can reproject them into the azimuthal projection I will actually use in the book.
