PDS_VERSION_ID = PDS3 RECORD_TYPE = "STREAM" OBJECT = TEXT PUBLICATION_DATE = 2018-04-09 NOTE = "AAREADME file for the Apollo 17 landing site map (1:15000)" END_OBJECT = TEXT END Introduction ============= This is an (ortho-) mosaic map and digital elevation model (DEM) of the Apollo 17 landing site (L15K 20.2/30.7East COMT). The map includes nomenclature, elevation contours, the astronauts' major geology stops, and rover traverses. It covers an area of about 14 km x 12 km of the Taurus-Littrow Valley, from 30.4294°E to 30.9162°E in longitude and from 19.9771°N to 20.3639°N in latitude. The image component of the map is an orthomosaic (0.5 m/pixel) that was created from images provided by the Lunar Reconnaissance Orbiter Camera (LROC) Narrow Angle Camera (NAC). Orthorectification of the images was based on a DEM (1.5 m/pixel) which was processed from LROC NAC stereo pairs. The DEM was also used to derive elevation contour lines, which were included in the map to indicate topography. The DEM and the orthomosaic are available as related products. We also determined the locations from where the Apollo 17 astronauts acquired station panoramas, and where they deployed ALSEP instruments. For this, we jointly analyzed the on-site Hasselblad photographs and the LROC NAC orthomosaic and registered the surface images to the orbital image. The determined camera and instrument positions were mapped in large scale station maps and are provided as ancillary cartographic products. More details on the localization approach and the station maps are provided by Haase et al. (2018). Reference: Haase, I., Wählisch, M., Gläser, P., Oberst, J., Robinson, M.

File Formats ============ All text documents and other meta information files such as descriptions, PDS object definitions and detached PDS labels are stream format files, with a carriage return (ASCII 13) and a line feed character (ASCII 10) at the end of the record. This allows the files to be read by various operating systems. Volume Contents =============== Files on this volume are organized into a set of subdirectories below the top-level directory. The following table shows the structure and content of these directories. In the table, directory names are enclosed in square brackets ([]). See the *INFO.TXT files in some directories for specific information on the files in that directory. In the directory descriptions below, "usable" refers to those images considered usable by the Apollo mission teams.
