DESCRIPTION
r.grow adds cells around the perimeters of all areas in a user-specified raster map layer and stores the output in a new raster map layer. The user can use it to grow by one or more than one cell, or like r.buffer, but with the option of preserving the original cells (similar to combining r.buffer and r.patch).SEE ALSO
