[GRASSLIST:1828] Creating a DEM

[michele.rocc at libero.it]

Hi,

I'm trying to create a DEM from a "scannerized" map, because of the 
large amount of feature I thought to extract in some way the contour 
lines using r.thin and r.line, then I heard that maybe there is som 
problems in doing that (something like r.surf.contour doesn't work fine 
yet..).
Well, is my idea possible to do? I know that any line will be 
reproduced but I wanted to eliminate manually by v.digit the "not-
contour" lines.
Anyway, even it I decide to copy all contour lines point by point, is 
there a working feature in GRASS to create the DEM?

Thanks,   Michele
