Abstract 1085. https://www.hou.usra.edu/meetings/lpsc2019/pdf/1085.pdf PROCESSING NOTES - Ames Stereo Pipeline v 2.6.0 was used to extract an elevation model and an orthoimage in GeoTIFF format. - Processing steps used USGS ISIS Version 3.4.12.6662 - CTX DEMs were aligned to the martian aeroid with Mars Orbiter Laser Altimeter Precision Experiment Data Records within the spatial footprint of the CTX DEM. - Rasters are in Sinusoidal Projection with a Central Longitude corresponding to the individual raster's center. KNOWN ARTIFACTS These are known artifacts present in most stereophotogrammetric elevation models. Artifacts present in this DEM might include Faceted areas in regions where original photographs were low contrast or dark and noise resulting from not-optimal camera look angles. These data are archived with no guarantee that they will have sufficient accuracy for every possible investigation. PRODUCT NAMING CONVENTION The naming convention for DEMs is: CTX_DEM_xxxxxx_yyAzzzB.tif where - CTX_DEM = indicating it's a CTX DEM product - xxxxxx = words specifying the sitename (a-g; up to 6 characters) - yyy = center latitude to the nearest degree - A = N for northern hemisphere, S for southern hemisphere - zzzz = center longitude to the nearest degree. - B = E for east of meridian, W for west of meridian Example: CTX_DEM_SITE-Y_28N120E.tif is a CTX DEM of Site Y located at latitude=28N, longitude=120E. ORTHO-RECTIFIED IMAGE PRODUCTS For each CTX DEM, we also produce ortho-rectified images (Digital Raster Graphics; DRG) with Ames Stereo Pipeline. The naming convention for these products is CTX_DEM_xxxxxx_yyAzzzB_DRG.tif, following details above.
