Mars Global Surveyor:
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
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.

PEDR Data Set Information under Data Set
ENVI Header Files
Header files for use with the commercial image processing software ENVI are provided in the
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.
