The LROC NAC Digital Terrain Models (DTM) contained within this directory were generated by NASA Ames Intelligent Robotics Group (IRG). This effort was a demonstration of automated mass production of DTM products using the Ames Stereo Pipeline software. These products are not part of any LROC data set in the Planetary Data System. They are provided in the EXTRAS directory on this volume as a convenience to the user. Files are located in the LROC RDR archive volume, with in the EXTRAS directory. The top-level directory LRO-L-LROC-5-RDR-V1.0/LROLRC_2001/EXTRAS/AMES_DTM/ contains two subdirectories: LRONAC_DTMS and LRONAC_THUMBNAILS. The LRONAC_DTMS sub-directory contains 1001 DEM products, which are comprised of the four files: 32 bit TIFF formatted DEM, 8 bit TIFF formatted Colormap, 8 bit TIFF formatted Hillshade and an 8 bit TIFF formatted Confidence Map. The LRONAC_THUMBNAILS sub-directory contains an 8 bit TIFF formatted thumbnail of the corresponding DEM Colormap product (1001 TIF images total). The work was funded by NASA SMDs Lunar Advanced Science and Exploration Research (11-LASER11-0112). For details on the generation of the products, refer to the abstract McMichael, S., Moratto, Z.M., and Beyer, R.A., LRO_NAC Mass DTM Pipeline, 46th Lunar and Planetary Science Conference, held March 16-20, 2015 in The Woodlands, Texas. LPI Contribution No. 1832, p.2491.

The 'COMMENT' and 'QUALITY' fields were created by the LROC SOC team to evaluate artifacts and missing data during a comparison with SocetSet DTMs. We have included them in this shapefiles in case they might be useful to those wishing to explore this dataset, but they were generated independently of the ASP Team.
