Hello, 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. 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. appreciate any help! thanks, ken |
