[GRASS-user] Why Does Re-projection Increase Disk Space Used?

[Rich Shepard]

   I have a source 28M DEM in a directory with geographic coordinates in
Lat/Long. When I re-project that to another location and dataset with
Lambert Conformal Conic projection the disk space consumed bloats to 106G.
That's more than a 20x increase. Why?

   In the destination location/directory there's no .tmp/ subdirectory with a
huge file.
