Topo Maps of Mars
It’s a bit presumptuous to call them “hiker’s maps,” as the European Space Agency does in its announcement, but the Mars Express scientists have generated several sample topographic maps of the Iani Chaos region of Mars, in an exercise that seems to be a proof of concept. Should such maps be made for the entire Martian surface, they envision more than ten thousand sheets at 1:200,000 scale. Higher-resolution downloads are available. I’m extremely keen on this, since I’m very fond of both topo maps and extraterrestrial cartography. Via Very Spatial and GeoCarta.
