[GRASS-user] r.watershed and bridges

[Micha Silver]

Using the new ASTER DEM data it seems to me that the resolution is good 
enough to show the elevation of the road surface on bridges crossing a 
riverbed. I see some places where the delineated stream comes to a 
bridge, then, instead of going under the bridge, turns 90 deg and runs 
along the road to a low spot, then crosses. So the bridge is "seen" a 
dam. What's the best way to deal with this? r.carve? or just locally 
editing the raster somehow?

Thanks,

Micha
