The Generic Mapping Tools (GMT) were recently described in the article:

  "Free Software Helps Map and Display Data," by Paul Wessel and Walter H.
  F. Smith, EOS Transactions, American Geophysical Union, Volume 72, Number
  41, October 8, 1991, page 441.

This article describes a package of tools and a library

  that can be used to manipulate columns of tabular data, time series, and
  gridded data sets and to display these data in a variety of forms ranging
  from simple x-y plots to maps and color, perspective, and shaded-relief
  illustrations.  GMT uses the PostScript page description languagem which
  can create arbitrarily complex images in gray tones or 24-bit true color
  by superimposing multiple plot files.  Line drawings, bitmapped images,
  and text can easily be combined in one illustration. ... GMT software is
  written as a set of UNIX tols and is totally self-contained [except for
  needing netCDF] and fully documented.  The system is offered free of
  charge to federal agencies and nonprofit educational organizations
  worldwide and is distributed over the computer network Internet.

The package  uses netCDF for  representing two dimensional  data  on regular
grids.  I've obtained and  built the software, but  haven't yet had a chance
to look at it in any detail.  If you want to get it, it's available from
