Dear list, I am trying to crop a raster map into a smaller area, but I am failing.
This wiki page link <https://grasswiki.osgeo.org/wiki/Cropping_maps> is quite clear: "Make boundary into mask using r.mask <https://grass.osgeo.org/grass72/manuals/r.mask.html> then copy raster source to new map (g.copy <https://grass.osgeo.org/grass72/manuals/g.copy.html>). All cells outside of the mask will be omitted from the new copy." r.mask vector=myarea g.copy --overwrite raster=OldRasterWithBigArea,NewRasterWithSmallArea r.mask -r I expected all cell outside were not going to be omitted, but replaced by NULL. Regards -- Marco
