The topographic map is a reprojection of NASA's equirectangular global map. Digital topographic data is not presently available. NASA released data briefly and then withdrew it. Hopefully it will be re-released once NASA and the IAU get done with their poo-flinging contest over coordinate systems.
Colors range from purple for low elevations and white for highest. The lowest elevation is about 22 km below the mean radius and highest is 19 km above. The transition from green to light blue marks zero (mean) elevation
