[GRASS-dev] GRASSplot: a tool for plotting GRASS maps with Python (Matplotlib and Basemap)

Dear GRASS users and developers,

In order to create consistent and attractive figures that combine the computational and data management abilities of GRASS GIS with the very developed set of plotting tools provided by Python’s Matplotlib (and Basemap toolkit), I wrote a small module to automate Python plotting of GRASS GIS data.

It currently works only for lat/lon locations (with Basemap doing the projection). It works well for rasters, but has some issues with vector extraction. I’ll be working on it intermittently, but have now posted it to my GitHub.

Code at:
https://github.com/awickert/GRASSplot

Basemap (Python) main page and gallery:
http://matplotlib.org/basemap/
http://matplotlib.org/basemap/users/examples.html

Hope some of you find this useful!

Thank you Andy.

The "NorthAmerica" example works for me (under Funtoo, grass64). I've seen a
couple of the examples in the above mentioned link. If this project works out
as you plan, it'll be really very nice. I only would like to point out to the
following Q&As which might be of your interest (as I was, coincidentally,
skimming through them today):

Hi Nikos,

Thanks for trying out the example and for the links, and please let me know if there is anything on your wish list for what should be included.

Cheers,

Andy
