Hi Martin,
I tried the command that Micha suggested v.db.addcol
map=contour_points_c...@permanent layer=1
columns="rast_value double precision" but this age the following error
The quotes " " around the "rast_value DOUBLE PRECISION" are necessary.
Just to check can we see the output of
v.info -c Contour_points_cats
You might also check that the points are all within the raster region.
i.e.:
v.info -g Contour_points_cats
r.info -g Dartmoor1
g.region -p
v.db.addcol Contour_points_cats col=rast_value DOUBLE PRECISION
Sorry <DOUBLE> is not a valid option
Sorry <PRECISION> is not a valid option
So through the GUI I added a column to the attribute table which gave
the command line out put
v.db.addcol map=contour_points_c...@permanent layer=1
{columns=rast_value double precision}
cheers!

how did you get this command?
It should be
v.db.addcol map=contour_points_c...@permanent layer=1
columns="rast_value double precision"
