coordinates, altitude, Euler angles, and ephemeris positions
[Tran et al., 2010; Burns et al., 2012].
From the final DEM the following derived products are
archived: orthorectified image, shaded relief image, color
shaded relief image, color slope map, and confidence map. An
orthorectified image has all topographical and camera
distortions removed. These images are cartographically true and
can be used to measure accurate distances. A shaded-relief
generated using the DEM simulates the Moon's surface with a
light source casting shadows on the terrain. Color coded
elevations are draped on the shaded-relief to form the color
shaded relief map. Finally slopes derived from the DEM are
color-coded. A confidence map indicates the quality of the
elevation estimate at each pixel. Refer to the readme file for the
description of the pixel values.
The DEM, orthorectified images, are archived as standard PDS
products in two resolutions (resolution of the DEM and
resolution of the original images), and the confidence map. The
shaded-relief, color shaded-relief, color slope map, and DEM
are in GeoTIFF format.
For more information on the methodology and preliminary error
analysis of the DEMs [Tran et al. 2010 and Burns et al 2012].
