The EXTRAS directory contains files which facilitate the use of the LROC
NAC and WAC data, but that are not actually required for the use or 
understanding of those data. 

The AMES_DTM directory contains NAC Digital Terrain Models generated using the 
NASA Ames Stereo Pipeline software (more information on the ASP software can be
found at https://ti.arc.nasa.gov/tech/asr/groups/intelligent-robotics/ngt/stereo/)
and created by the NASA Ames team. Please review the README.TXT file within the
directory for more information about the products and their generation.

The ANAGLYPH directory contains TIFF-formated images from NAC stereo observations.
Details regarding the creation of the anaglyphs prodcuts can be found in the
following abstract http://meetingorganizer.copernicus.org/EPSC2012/EPSC2012-486-2.pdf

The BROWSE directory contains browse images for the NAC and WAC RDR products
in the published volume. Subdirectories within the BROWSE directory are
organized by RDR product type (ex. NAC_POLE_SOUTH or WAC_MONTHLY). 

The SHAPEFILE directory contains ESRI formatted shapefiles 
generated by the LROC Team, from NAC or WAC imagery (shapefile
specification information can be found in the PDF file
http://www.esri.com/library/whitepapers/pdfs/shapefile.pdf).
