[GRASS-user] DEM re-projection: change elevation units

   The source DEM has projection units in feet and both geographic
coordinates and elevations are in those units. Re-projecting these data to
the metric equivalent transforms the x, y coordinates from feet to meters
but leaves the elevations in feet.

   Is there a script that runs r.mapcalc on all cells and converts each
elevation from feet to meters? Or, is there a different approach.

   I need the same units for x, y, and z values.

TIA,

Rich
