Generic Mapping Tools

From Wikipedia, the free encyclopedia

Generic Mapping Tools or GMT is a collection of open-source software which may be combined to generate maps in many different ways.

GMT contains tools for processing x, y and x, y,z datasets, including rasterisation, filtering and other image processing operations, and various kinds of map projections. A comprehensive collection of free GIS data are included, such as coast lines, rivers, political borders and coordinates of other geographic objects. Further data (satellite imagery, digital elevation models etc.) can be converted from other sources and imported. The resulting maps and diagrams are stored in Encapsulated Postscript (EPS) format. The system is operated from the command line, enabling scripting and automation of routine tasks. More or less comprehensive graphic user interfaces are available from third parties, as well as web applications, bringing the system's functionality online.
