GMT is a collection of public-domain Unix tools that allows you to
|
||
|
|
manipulate x,y and x,y,z data sets (filtering, trend fitting,
|
||
|
|
gridding, projecting, etc.) and produce PostScript illustrations
|
||
|
|
ranging from simple x-y plots, via contour maps, to artificially
|
||
|
|
illuminated surfaces and 3-d perspective views in black/white or
|
||
|
|
24bit color. Linear, log10, and power scaling is supported in
|
||
|
|
addition to 25 common map projections. The processing and display
|
||
|
|
routines within GMT are completely general and will handle any (x,y)
|
||
|
|
or (x,y,z) data as input.
|
||
|
|
|
||
|
|
This port installs only the GMT manpages, there is a tutorial and
|
||
|
|
documentation in .ps, .pdf and .html format on the ftp site, too.
|
||

|
In case you look for data to plot, there is topological data at
|
||
|
|
ftp://topex.ucsd.edu/pub/global_topo_2min/topo_8.2.img
|
||
|
|
(140MB, covers nearly the whole earth)
