Shapefile of LROC Digital Terrain Models on the lunar surface and corresponding error analysis data. Polygons were generated from the DTM derived products using GDAL and OGR tools. The shapefile uses Moon_2000 geographic coordinate system and contains expanded error metrics compared to NAC DTM readmes. It contains footprints for all NAC DTMs released up through 2024-03-15.
