Lunar polar topography derived from Clementine stereoimages

Clementine stereoimagery has been used to produce digital elevation models of the Moon, at a scale of ∼1 km/pixel. These models cover regions poleward of 60° in both hemispheres and reveal topography beyond that covered by the Clementine laser altimeter or Earth‐based radar. By combining these polar terrain models with the current Clementine laser altimeter data we have produced a global topographic map of the lunar surface. Several topographic features in the new polar topographic data set are described, including three previously unrecognized pre‐Nectarian impact basins. Several known basins have also been mapped, including the southern extent of the South Pole‐Aitken basin, and other previously suspected basins have been verified.
