The topographic map is derived from a monochrome NASA Geotiff map. The original map shows a pronounced equatorial bulge. Corrections were made by taking the difference between an ellipsoid matching the major and minor axes and a sphere of mean radius. There are published maps corrected for the ellipsoid but no published DEM's.
The Raw Altimetry maps show the pronounced equatorial bulge of Ceres. Raw Altimetry A uses the same scale as the other maps and goes off-scale at the poles and equator. Raw Altimetry B uses a scale that shows the entire range of elevations. Color bands on both are at 500 meter intervals.
Kerwan, right of center, is the largest crater on Ceres and evidently a very old won. It is quite shallow for its size. If it had a central peak, it might have been destroyed by the impact that created the small crater in the center.
