Moon LRO NAC Conf Apollo 15 26N004E 150cmp
This raster dataset represents a confidence value or figure of merit (FOM) for each pixel for the digital elevation model (DEM) as extracted from the Lunar Reconnaissance Orbiter Camera (LROC) Narrow Angle Camera (NAC) stereo images. The original DEM product is generated from stereo images acquired at approximately 0.5 meters/pixel resolution, which allows an output DEM resolution of 1.5 to 2.0 meters/pixel using a softcopy photogrammetry system. However, in some cases, LROC DEMs were also generated at lower resolutions. The DEM was registered horizontally and vertically to LRO's Lunar Orbiter Laser Altimeter (LOLA) data.

General
- Purpose
The NASA Constellation Program (CxP) has identified 50 regions of interest on the Moon that the LROC NAC will image. A DEM is generated for each of these regions using the acquired NAC images. High resolution DEMs will be essential for identifying potential landing sites, landing site hazards, placement of landed assets on the surface, as well as other surface operations and navigation needs. Site-specific DEMs will also serve as a foundation for ortho-projection and control of local/site mosaics.

- Process Description
Figure of merit (FOM) values are automatically collected by SOCET SET 5.x as part of the stereo correlation for the output DEM. These values are then simplified into a more generically defined LMMP confidence value as listed in the logic section of this document. > The shadows in the DEM were masked and images were used to fill in the shadowed areas where possible.
