[GRASS-user] problem in v.drape command

[Jerry Nelson]

Is this a place where the error message could be made clearer? For example,
could it add possible sources of the problem such as the one Markus
indicated, or are there too many possibilities for ways to do it wrong?

The problem is that the vector map is bigger than the raster map.
You need to use

g.region rast=dem
v.in.region box
v.overlay ... with box and your vector map to restrict the vector map to
the DEM size
v.drape ... with the reduced vector map.
