so many lists?...
however, I am here now too
I will try to see if students can work on an USLE excercise (thaught in
Zurich originally) with Sextante instead of ESRI's Spatial Snalyst in
the winter term. This way, they could just take stuff home. I actually
plan(ned) to start go through these excercises today.
