If you want only to display scanned map, grid-units and grid commands

ok, small typo.
When I delete grid-units and grid command therion complains about 
missing grid (I produce only 2d map at the moment)! So I think I have to 
use them.

But now an other error occurs (dimension too large). I think it is from 
pdftex. I have a scan from a topographical map and specified the 
koordinates with UTM.

Thanks
