Implementation of DRASTIC in GRASS

[Dr. Antonio Lo Porto]

Dear Alejandro,
we did some work with DRASTIC.
We studied the growndwater vulnerability of the LUCCA plain (Tuscany - 
Italy) in an area of about 200 km2.
The DRASTIC classes were overlaid on actual and planned landuse maps to 
highlight the "geological settings x landuse" worse combinations where 
detailed management models had to be run.
The DRASTIC model were obtained using both IDRISI (for DOS) and GRASS (on 
Linux). We did not use particular scripts using r.mapcalc and we found 
GRASS to be quite powerful, a little bit less user-friendly than IDRISI 
(but we were then newcomers in the GRASS world), but infinitely more 
effective than IDRISI as regarding printing (....ok, it was an unfair play!).
Please let me know if you need more infos.
Ciao.
Antonio Lo Porto
