I tend to use `v.extract` to "cut out" the vector polygon I want to use as a region, convert it to a raster with `v.to.rast use=val val=1 ...`, and do my final raster operation with the new raster as a mask (`r.mask`). I'm sure there are several other ways. -- Brad Douglas <rez touchofmadness com> KB8UYR/6 Address: 37.493,-121.924 / WGS84 National Map Corps #TNMC-3785 _______________________________________________ grassuser mailing list [email protected] http://grass.itc.it/mailman/listinfo/grassuser
