sorry for the last empty post, yahoo is quite broken these days and ate my
reply.
key points:
- resample with r.resamp.interp or r.resamp.rst.
- use low res map as mask to crop interp'd map back to known borders if you
like to do that.
- apply mask to new map with 'r.mapcalc "new=old"' with MASK in place.
- use r.grow to "smear" values outwards
- r.resamp.rst may be good enough at edges so that you don't need r.grow.
