[GRASS-user] scriptable commands for data analysis?

GRASS GRASS user
1

I have a couple of tasks that I think GRASS might be useful for,
related to analyzing geographic data. One is finding clusters
of locations (e.g., enough users to support a local user group).
Another is finding adjacent US counties, based on

  http://www-atlas.usgs.gov/mld/countyp.html.

Ideally, I'd like to find some batch-mode commands that could be
scripted to generate collections of information. Suggestions,
anyone?

Hello,

have a look at http://grass.gdf-hannover.de/wiki/GRASS_AddOns for scripts.

Some scripts are using GRASS and R and doing cluster analysis which might be
interesting for you as starting point (have a look at this thread
http://grass.itc.it/pipermail/grassuser/2006-July/035305.html or
http://lists.qgis.org/pipermail/qgis-user/2006-July/000298.html) .

cheers, Martin
