Hi, I thought I created a clipped DEM by rasterising an irregular vector boundary and then using a mask to create the clipped DEM from a rectangular DEM.
For example: ----- # convert vector border to raster v.to.rast input="border" output="border" use="cat" type="area" layer=1 value=1 rows=4096 | # set the mask to the raster border r.mask border # create the clipped DEM r.mapcalc >dem_clipped=dem_full # remove the mask r.mask -r ----- But it turns out I was wrong, the 'clipped' raster just contains NULL values outside of the border raster. What did I do wrong? Is there a better way to clip a raster to a vector boundary?
