Clementine had a rather large elliptical orbit around the Moon so the resolution varied. It imaged most all of the Moon but there were areas that were missed like little slivers at the poles. The USGS made a globe map using this information and some software blending to fill in the gaps.
Lunar Clementine Topographic Globe (shown on the left): The photomosaic that forms the base for this globe combines a gray-shaded relief airbrush image with color-coded topographic data. The shaded relief data provide interpretations of lunar morphology based on lunar images and were used as a grayscale image for this global mosaic. Topographic data from the Clementine laser altimeter were combined with topographic data collected photogrammetrically from Clementine stereo images. The resulting topographic product was colored based on elevation value and combined with the shaded relief data to form the final photomosaic.
