[GRASS-user] min and max raster within polygons

[Dave Roberts]

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.

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

Thanks, Dave
