          Description

          Here's a map of Ganymede, a project 2 years in the making. This map projection includes data from 6 images (the best 5 are shown), captured over the last two Jupiter apparitions. Mouse-hover or click Here for the comparison of my image against those based off Voyager & Galileo. There are a few spots that don't match perfectly, probably due to either resolution limits or poor map computation, but I'm happy with the general agreement.
