The purpose of the software is to calculate the undulation between the WGS84 ellipsoid (GPS height) and the EGM96 geoid (mean sea level) in MATLAB, based on the C code in the "egm96-f477.c" project
C translation of EGM96 (earth height model) implementation (namely, f477.f) available at http://earth-info.nga.mil/GandG/wgs84/gravitymod/egm96/egm96.html
libTopo and TopoMap are tools to use, convert, analyze and display topography maps such as ETOPO2, ETOPO5 and GLOBE. TopoMap is the command line interface to convert topography databases to raw data, images, etc...
