Mars Global Surveyor: MOLA IEGDRs

Initial Experiment Gridded Data Records

The MOLA Initial Experiment Gridded Data Records (IEGDRs) are preliminary versions of the Mission Experiment Gridded Data Records (MEGDRs), global topographic maps of Mars. The IEGDRs were generated early in the mission, while the MEGDRs include data accumulated over the entire mission.

The IEGDR data set has been superseded by the MEGDR data set. We recommend the use of the MEGDR data set rather than the IEGDR data set, as it is more mature, incorporates more data, and is available at higher resolutions. However, the IEGDR data set is archived offline and is available on request to geosci@wunder.wustl.edu.
