GMT

the program that actually creates the maps

GMT (The Generic Mapping Tools) is a software package to create high-quality postscript maps in various projections. It was developed by Paul Wessel (University of Hawaii at Manoa) and Walter H. F. Smith (NOAA).

As pointed out in the manual to version 3.0 "it appears that around 5000 scientists and engineers worldwide are using GMT in their work". This includes standard x-y-plots as well as complicated maps combined with other geographical referenced data.

GMT comes as a set of more than 50 programs and tools, each tailor made for their specific task. Just five of these programs are used

for the Online Map Creation here. This might give you an idea of the range of applications covered by the GMT-package.

GTM programs are either called from the command-line or from shell-scripts. This is a highly effective way of customized map creation. A GUI is deliberately not included in the package and the Online Map Creation site is not intended to be or become one. It should be regarded as a "appetizer for the real thing" and a reference to the developers of GMT and the programs.
