urn:nasa:pds:mgs_mola_topography_derived:data_megdr_polar:megc_s_256 1.0 1.23.0.0 Product_Observational 2026 This data product accompanies the topographic and shape maps of the south pole of Mars at a resolution of 256 pixels per degree. It contains the number of observations per pixel that have been used to produce the data products. The map is in the form of a binary table. Producer David E.

Carriage-Return Line-Feed megc_s_256.hdr 0 7-Bit ASCII Text The ENVI header is a separate ASCII file that includes basic image data file characteristics. ENVI will read both files and use the map projection information in the header file to correctly display the image. The header files are provided because ENVI is not able to import the map projection information directly from the MEGDR image labels. Carriage-Return Line-Feed
