Hi GRASS users,
how to change the boundaries of a raster map (simply expand the
border) without any automatic modification of map resolution as it
will happen when using "r.region map=.. n= ..s=.. w= e=.." ?
Thanks for some hint.
Micha:
How about changing the current region with g.region, then use r.mapcalc
to create a copy of the original at the new extents?
A reminder that "r.region" might be useful as well in this case.
Yes, but the OP asked not to use r.region since it changes also the
resolution. It recalculates the res so as to keep the same number of
rows and columns.
Kind regards, Nikos
