I have a raster map (dem) and I want to select a region of the raster
corresponding to a polygon that is in a vector map. What is the best
way to do this? It looks like r.in.poly might be along the lines of
what I need but in that case I think I would need to generate the ascii
poly file first but I'm wondering if there is a better way? Seems like
there should be a single command to do this.<br>
<br>
My vector map has 45 polygons with cat values 1..45, so I would like
to get a section from my raster map corresponding to one of the
polygons specified by cat value.<br>
<br>
appreciate any help!<br>
thanks,<br>
