Generic Mapping Tools (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. GMT is developed and maintained by Paul Wessel and Walter
|
|
H. F. Smith with help from a global set of volunteers, and is supported
|
|
by the National Science Foundation. It is released under the GNU General
|
|
Public License.
|
|
|
|
GMT requires netcdf.
|
|
|
|
With the 4.5.7 GMT release, there is only a single coastline archive to
|
|
download. Accordingly, I've modified the script to use all the coastline
|
|
data (removing the option of using only a subset of the coastline files).
|
|
|
|
Please note, Shewchuk's triangulation routine used in some parts of GMT is
|
|
not distributed under the GNU Public Licence. If you work for a for-profit
|
|
organisation, you should read Shewchuk's copyright statement first (in
|
|
src/README.TRIANGLE). This script enables the (much faster) Shewchuk
|
|
triangulation routine by default; should you need to change this behaviour,
|
|
set SHEWCHUK to "no" in the build script.
