PLOTMAP: Geophysical and geological applications of good standard quality cartographic software

PLOTMAP, an interactive computer program that plots data in geographical coordinates in the most used cartographic projections is described. The program conforms to good cartographic standards and contains various drafting options. Its small size and transportability make it flexible, and easily customized by the user at different installations. PLOTMAP also is a preprocessor for more sophisticated spatial analysis systems, in that it creates and executes command procedures tailored to the user's input data, whereas maintaining the graphic output in the selected projection domain. Mathematical expressions, examples of interactive sessions and the FORTRAN 77 source code are provided. The program can run in GKS and CALCOMP environments. © 1989.
