Geographic mapping programs

Some modelers wish to express things in the form of a map depicting geographic movements of goods, production etc.  Some mapping programs like MAPVIEWER from Golden Software use CSV input formats and can be directly used with the techniques above once the map has been set up.  GAMS corporation has also released a library include file called GAMSMAP which uses MAPINFO's PROVIEWER mapping system as described on the GAMS web page at Exporting to MapInfo Maps.

Tom Rutherford has also developed a GAMS interface to Mark Horridge' s SHADEMAP a tool for shading or coloring regions of simple maps and this has been extended by Uwe Schneider and called GAMS-SHADEMAP.
