Well, there is already r.prominence:
http://grass.osgeo.org/grass65/manuals/addons/r.prominence.html
See also this older mailing list post:
http://lists.osgeo.org/pipermail/grass-user/2009-November/053220.html
The source code in the Add-ons repository seems outdated.
I have attached a more recent version in which I have outsourced
the normalization functions to a separate module (r.normalize),
also attached.
I doubt that r.prominence captures the entire concept of
"prominence" as used in mountaineering, but maybe it's a
starting point.
Best,
Ben

Hi all,
when searching for a suitable topic (smaller project) for one student
of mine I found [1,2].
"""
Create a new GRASS module to find the topographic_prominence of peaks
from a raster elevation map within the region. (probably this would
only make up 1/4 to 1/2 of a multi-part GSoC project)
"""
I don't know this topic enough, is there anyone who has any opinion,
suggestion or comment?
Thanks in advance, Martin
