Data Center Description
GMT is an open source collection of ~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 ~30 map projections and transformations and
comes with support data such as coastlines, rivers, and political boundaries.
GMT is developed and maintained by Paul Wessel and Walter H. F. Smith with help
from a global set of volunteers, and is supported by the National Science
Foundation. It is released under the GNU General Public License.
