Geographic mapping tools that produce EPS illustrations

Generic Mapping Tools is a collection of ~60 GNU/Linux tools that allow users to manipulate (x,y) and (x,y,z) data sets (including filtering, trend fitting, gridding, projecting, etc.) to produce Encapsulated PostScript File (EPS) illustrations ranging from simple x-y plots through contour maps to artificially illuminated surfaces and 3-D perspective views in black and white, gray tone, hachure patterns, and 24-bit color. GMT supports 25 common map projections plus linear, log, and power scaling, and comes with support data such as coastlines, rivers, and political boundaries. Since the package is quite large, the authors suggest looking at the list of mirrors on the page to ensure that you download from the one closest to you.
