-A similar trick can be used to cut a portion of the original map, apply a mask, etc. A more capable module for those applications is ''r.resamp.interp'' which can be used instead of ''r.mapcalc'' to peform bilinear and bicubic interpolation for the grid.
+A similar trick can be used to cut a portion of the original map, apply a mask, etc. A more capable module for those applications is ''r.resamp.interp'' which can be used instead of ''r.mapcalc'' to peform also bilinear and bicubic interpolation for the assigned raster grid. A nearest neighbor interpolation can also be performed by the ''r.resample'' module as well.
