Abstract
Estimates of the elevation of the lunar polar regions are uncertain to a few km. Galileo stereo images of the north polar
region were used to derive a new topographic map, partially filling the gap in Clementine LIDAR topography northward of 80°,
and providing an independent constraint on lunar polar topography and solar illumination. Our Galileo elevation model has
an estimated vertical precision of ∼200 m, and a measurement footprint of ∼9 km. These new data show that the north polar
region (frontside) is, to within the margin of error, consistent with radar derived estimates.
