Has anyone out there had any experience rotating DEM
raster maps? Or any other raster maps?Bob Harrington

no experience, but some info to get started.
export the grass raster map, create a ppm file,
use pnmrotate -noantialias (from related),
import back into grass.
As far as keeping the georeferencing/map quality good,
be careful.
I have a v.rotate command started (which may get finished
by the end of the year). Is there a need for a r.rotate
among others?
