allow me one more additional comment.
You did mention the python interface and recomended it as a good way to
program a interface for GRASS-GMT interaction.

I am not a coder but once stumbled accross the basemap class of python
matplotlib:
http://matplotlib.sourceforge.net/matplotlib.toolkits.basemap.basemap.html

I don't know whether this is a full implementation of GMT in Python but
seems to use part of its logic.

Thanks for the ideas Tim. Paul has responded to this downstream, but I just
wanted to mention that I was referring to the GRASS-Python bindings in my
previous correspondence and article.

However, it looks like it may soon be possible with GMT 5 to glue both GRASS
and GMT together with python!! that would be something!

Dylan,

This would be awesome: "… looks like it may soon be possible with GMT 5 to glue both GRASS and GMT together with
python…" — one of the *unfounded" criticisms of GRASS is it's inability to produce nice publication quality maps. Well,
this would lay that myth completely to rest.

Indeed. If I can get a little bit of help on working with the python-GRASS
bindings I might be able to post a follow-up article detailing how this will
work.

Dylan,

I wish I knew some Python, as I would like to be able to help. I hope to contribute some GRASS modules this year related to some of the work I do.

Regards,
Tom

There is a nice 10 minute tutorial for programmers of other languages here:
  http://www.poromenos.org/tutorials/python

To use the GRASS SWIG/Python interface to libgis:
(work in progress; you can do most things with modules without this)

$ cd /usr/src/grass63/swig/python
$ make

GRASS> cd /usr/src/grass63/swig/python
GRASS> python
..

import os, sys
import python_grass6 as pyg6

pyg6.G_gisinit('')

mapset=pyg6.G_mapset()
print mapset

user1

print pyg6.G_database_unit_name(1)

meters

print pyg6.G_database_projection_name()

UTM

print pyg6.G_database_datum_name()

nad27

pyg6.G_yes("Does it work?", 1)

Does it work?(y/n) [y] y
1

print pyg6.G_getenv("GRASS_GUI")

Python is pretty easy to learn and much easier to work with than shell
scripting. There are some very good books that can get you started.

Well, I am just in the same situation as you here...

But seems that so many applications are using Python now or are shifting towards it...

Some guy of your organization did some work on it, too:
http://www.cdc.noaa.gov/people/jeffrey.s.whitaker/python/gmt/gmt-src/doc/html/public/gmt.gmt-module.html

thanks for the pointers Hamish. I will have to look into this some more.

Anyone else have some experience with the SWIG/python stuff?

cheers,

dylan
