Mars Global Surveyor: MOLA

The Mars Orbiter Laser Altimeter (MOLA) generated altimetry profiles used to create global topographic maps. The MOLA instrument stopped acquiring altimetry data on June 30, 2001, and after that operated in passive radiometry mode until the end of the MGS mission. MOLA data sets are produced by the MOLA Science Team and archived by the PDS Geosciences Node.

MOLA Products and IAU Coordinates

The final version (Version L) of the MOLA PEDR data set was generated using the IAU 2000 coordinate system. The final version of the MOLA topographic maps (MEGDRs) was generated from the Version L PEDRs, and therefore also uses the IAU 2000 coordinate system. Older versions of MOLA PEDRs and topographic maps were created in the IAU 1991 system. For more information, see the PEDR Data Set Information under Data Set Overview.

ENVI Header Files

Header files for use with the commercial image processing software ENVI are provided in the EXTRAS directory of the MOLA MEGDR archive. These files are provided because ENVI is not able to import the map projection information in the MEGDR labels. See EXTRINFO.TXT for more information.
