Did you do: g.copy rast=boundary_raster,MASK or alternatively: r.mask input=boundary_raster -o (-o for overwrite) ?

Hello, I while ago I asked how to cut a small map from a larger one using the region settings as boundary for the small map: http://n2.nabble.com/r-mapcalc-changes-color-table-td4072836.html#a4072836 I tried this again: Approach 1: r.mapcalc r.mapcalc "cut=if(boundary_raster, large_map, null())" Approach 2: r.resample r.resample input=large_map output=cut I notice the that using Approach 2, the areas that was outside the set region is white. The underlayung rasters are not visible (or only if I set the opacity of "cut" to a low value). If I use Approach 1 with r.mapcalc, the areas outside the region are really NULL() (=transparent) and underlaying larger rasters are visible. Only that the result "cut" from r.mapcalc has a new colortable. Am I doing something wrong? Why is the no such command r.cut? Thanks in advance for your help, Timmie _______________________________________________ grass-user mailing list grass-user@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/grass-user
