[GRASS-dev] Topographic prominence in GRASS

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

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The source code in the Add-ons repository seems outdated.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
