[GRASSLIST:7566] Re: Synergy between Grass/Python/GMT

[David Finlayson]

I'd be happy to share it, but frankly it's pretty crude. I'd be
embarrassed to foist this off as a good example of either Grass or
Python (though maybe it is a good example of how flexible this
combination is, even for light-weight programmers). The class simply
wraps an interface around a few standard GRASS commands and captures
the results (r.region for example). My dream is to write a real Python
interface to the Grass programming interface, but that project is on
hold until I finish my PhD.

Is there a good place on the wiki for sharing scripts? When I get this
GMT thing polished up I think it will be quite useful for folks who
use GMT.
