Daniel Macháček released his topographic map of Mars, based on the latest probe data, in November 2014. It uses the Mercator projection between 65° north and 65° south latitude and stereographic projections for the poles. It can be downloaded in insanely high resolution: 17,400×14,700 (78 MB JPEG, 106 MB PDF). His blog post (in Czech: use the translate button) has all the technical details. I particularly like the colour scheme he used for elevation data: the low-lying areas are coloured like deep oceans, which seems appropriate. [Maps on the Web]
