Mars Global Surveyor: MOLA PEDR Software

The following software is provided here and on MOLA archive volumes for accessing data in PEDR files:

  • MPROF - an IDL script that generates topography profiles
  • SPLITORB - an IDL script that separates a PEDR into single orbits
  • PEDR2TAB - a Fortran program that generates an ASCII table of PEDR data

The software is provided for Sun/UNIX, PC/Windows, and Macintosh platforms and has been tested by the PDS on those platforms. 

Questions about these software products may be addressed to the PDS Geosciences Node at geosci@wunder.wustl.edu.

MPROF

MPROF is a script for use with the commercial image processing software package IDL. MPROF can be used only on a computer that has IDL software installed, either a UNIX or PC system. The script generates topography profiles from PEDR data products. MPROF was originally written by C. David Brown, Dept. of Earth and Planetary Sciences, Washington University. It was modified by Judd Bowman, PDS Geosciences Node, Washington University, for use with these PDS archive volumes.

See also the SPLITORB program below, which is intended for use with MPROF.

SPLITORB

SPLITORB is an IDL script that reads a PEDR containing data from multiple orbits and generates separate PEDR files each containing data from a single orbit. This script is meant to accompany the MPROF script described above. MPROF was written to operate on PEDR files that contain only one orbit's worth of data. A Mapping Phase PEDR must first be broken down into separate orbits using SPLITORB before MPROF can be used to plot the data.

SPLITORB was written by Judd Bowman, PDS Geosciences Node, Washington University. It was adapted from the C program SPLITPEDR by C. David Brown, Dept. of Earth and Planetary Sciences, Washington University.

PEDR2TAB

PEDR2TAB is a program that reads MOLA PEDR files and produces an ASCII table of selected fields, one line for each altimetry shot detected. The user may choose to see all ranges, or only those that are/are not ground hits, in a selected region. The user may output any of eight groups of MOLA instrument values. By default, topography, range, planetary radius, and flags are output. The program is written in Fortran 77 with MIL-STD-1753 and other extensions.

PEDR2TAB was written by Gregory Neumann, MOLA Science Team, NASA/Goddard Space Flight Center.
