Generic Mapping Tools (GMT) is a set of programs for easy generation of maps, written under the GPL-license by Paul Wessel and Walter H. F. Smith.
GMT reads coastline, rivers data -and similar input files- and generates
"layers" of PostScript code (or EPS).
The input can be points, vectors or raster information, as long as it is related with
geographical coordinates.
GMT applies one of multiple projections and creates a PS file.
Eg, the previous TT
map projection from the Xerox PARC Map Viewer is the Mollweide.
TTmaps project makes use of GMT tools to create
World and
European
maps of the testboxes.
