- Generic Mapping Tools
Generic Mapping Tools (GMT) is an
open source collection of tools for processing and displaying xy and xyz datasets, includingrasterisation , filtering and otherimage processing operations, and various kinds ofmap projection s. A comprehensive collection of freeGIS data are included, such ascoast lines,river s, politicalborder s andcoordinate s of other geographic objects. Further data (satellite imagery ,digital elevation model s etc.) can be converted from other sources and imported. The resulting maps and diagrams are stored inPostScript (PS) orEncapsulated PostScript (EPS) format. The system is operated from thecommand line , enabling scripting and automation of routine tasks. More or less comprehensivegraphic user interface s are available from third parties, as well asweb application s, bringing the system's functionality online.GMT was originally created in 1988 by Paul Wessel and Walter H. F. Smith. It is predominantly but by no means exclusively used by Earth Scientists. Besides its strong support for the visualisation of geographic data sets, it contains tools for processing and manipulating multi-dimensional datasets.
