DESCRIPTION

54       r.grow  adds  cells around the perimeters of all areas in a user-speci‐
55       fied raster map layer and stores the output in a new raster map  layer.
56       The  user  can  use  it  to  grow by one or more than one cell, or like
57       r.buffer, but with the option of preserving the original cells (similar
58       to combining r.buffer and r.patch).
