PC Software Download - G99SSS

G99SSS

[2011 Feb 09] Intg v3.11

Description

The executable programs (INTG.EXE and XNTG.EXE) were compiled for use on an IBM-compatible PC. The INTG.EXE program will interpolate geoid heights from data files using user-provided coordinates. The XNTG.EXE program will extract sub-grids from the binary data files, as well as convert back and forth between binary and ASCII, or just give statistics about a data file. To use G99SSS, the INTG.EXE executable and at least one data file must be downloaded. You need only to select those data files that cover your region, and the INTG.EXE program will recognize which files are present. If you are running G99SSS on a 386 machine, you will also need to download the DOS extender file.
