Hello, I have calculated raster file based on a DEM with some r.mapcalc commands. As a result, my raster file with the areas of interest is smaller than the whole region. How do I intersect the landcover vector of the whole region to get a new landcover vector with only those polygons contained within the areas of interest of the raster?
Basically, I'd like to run v.extract/v.overlay not on a vector-to-vector basis but on a vector-to-raster basis. If I convert my raster to a vector file the GRASS program freezes the computer because the calculted rasters seem too many values. I would highly appreciate to receive hints on this issue. The only past post I found was this. but it pointed to non GRASS solution: http://www.nabble.com/Intersection-of-Vector-polygons-with-raster-ts19496096.html Kidn regards, Timmie _______________________________________________ grass-user mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/grass-user
