GEOID99 Interpolation Software

[May, 2002]

Description

These programs were developed as alternatives for their Fortran counterparts. 'C' code was developed with small memory requirements in mind. Unlike the Fortran code which can require a large amount of ram, this utility is very memory efficient. This code is useful for DOS or other Microsoft OS's in which memory is limited, such as WindowsCE. The big difference between these utilities and their Fortran equivalents is that they can only utilize a single *.bin file. The Fortran versions by contrast can utilize many grid files. These *.bin files are NGS formatted GEOID99 geoid files.
