The Ordnance Survey (national mapping agency for the UK) has just released their first map of a region on another planet. It's a high resolution relief shaded contour map, and includes the area of Mars where ExoMars will land in 2018. Here is a close up view of it with the ESA landing ellipse in Oxia Planum superimposed.
Preview of the full map - low resolution, again with landing ellipse.
The full resolution image of the map plus landing ellipse is here. I've jpeg compressed it from 67.2 megabytes to under 20 megabytes for easier download - but with no jpeg artifacts as far as I can see. It's 11574 by 9921 pixels or 114,825,654 pixels or 114.826 mega pixels

The map was made by the cartographer Chris Wesson, and covers about 10 million square kilometers, or about 7% of the surface area of Mars. He was asked to do it by Dr Peter Grindrod, of Birbeck college, University of London.

The earlier ESA countour maps of Mars were photographs from orbit with countours automatically generated and superimposed. See Want to Hike on Mars? (high resolution images of these auto generated countour maps available here).
