Mars is a funny planet.  What you see is not what you get.  Most maps of Mars show the features of Mars as seen by NASA spacecraft orbiting Mars.  What most astronomers actually see from Earth is the albedo of Mars – the light and dark patches that overlay those features.  This map shows the albedo, with some of the major features labeled for reference.  All the data is from NASA spacecraft and are provided courtesy NASA/JPL-Caltech.  NASA has an extensive library of images and tools.  One of the more helpful tools is the Mars Trek tool.  Anyway, feel free to download this low resolution map for your personal use.  Just click on it to see it full sized, then right-click on the full sized image and select SaveImage As…  I hereby grant individuals rights for personal use.  If you want to purchase a full resolution version, let me know in the comments, or email.  Thanks and enjoy!
