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.
Occator (a bit left of lower center) sounds like it should be the name of an action figure. It isn't the largest crater on Ceres but might be the best known because of its bright white spots (faculae) that are probably salts erupted from the interior.
