The Generic Mapping Tools (GMT) are an open source collection of about 60 tools for manipulating geographic and Cartesian data sets (including filtering, trend fitting, gridding, projecting, etc.) and producing Encapsulated PostScript File (EPS) illustrations ranging from simple x-y plots via contour maps to artificially illuminated surfaces and 3-D perspective views. GMT supports about 30 map projections and transformations and comes with support data such as coastlines, rivers, and political boundaries. GMT is released under the GNU General Public License.
