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 GSHHS coastlines, rivers, and political boundaries.
Information taken from the GMT page: The preferred way to obtain the necessary GMT files is to interact with the GMT web page install form at gmt.soest.hawaii.edu. Filling out the form will return to you a parameter file that you may use with the install script that you can download from the same install page.
