[GRASS-user] new module: r.surf.volcano

[Hamish]

Hi,

I just added a new module to the wiki addons page: r.surf.volcano

It creates an artificial surface resembling a seamount or cone volcano.
The user can alter the size and shape of the mountain and optionally
roughen its surface.

http://grass.osgeo.org/wiki/GRASS_AddOns#r.surf.volcano
http://trac.osgeo.org/grass/browser/grass-addons/raster/r.surf.volcano

It's a shell script and requires GRASS 6.3.0 or newer.
I'm using it for testing hydrodynamic flow models and r.sun.
