v.to.rast inp=new_mountains out=new_mountains attr=cat use=attr
r.univar map=srtm zones=new_mountains

Friends,
I have succeeded (finally) in heads-up digitizing the mountain ranges of
the Rocky Mountains. Now I want to know the minimum and maximum elevation
for each range. I have a suitable DEM, but I cannot figure out a
combination or r.mapcalc or other that will give me this.
I would probably use r.univar with zones option. You have to first
rasterize your vector of ranges.

Clearly, what I want is to query a raster within a boundary, not at a
point.
Thanks, Dave
