Description: The General Cartographic Transformation Package (GCTP) is a system of
software routines designed to permit the transformation of coordinate
pairs from one map projection to another. The GCTP is the standard
computer software used by the National Mapping Division for map
projection computations.

Because of requirements internal to the EROS Data Center, the GCTP software
was converted from FORTRAN to the C programming language, and several new
projections were added. During the conversion process, the software was
tested on the following UNIX systems: Data General running DG/UX Release
5.4R2.01 AViiON, SUN running SunOS Release 4.1.3, and Silicon Graphics
running IRIX Release 5.3 IP7. In addition, the software has also been
verified against the current National Mapping Division (NMD) GCTP
software. This new version, GCTPC, is being made available informally
on a 'user-beware' basis. EDC assumes no responsibility for the accuracy
of the routines in this package.
