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.
