Dear Vincent,
thanks for your idea. I wasn't aware of the possibility to snap a vector
map to another one. Good thing to know!
However, it didn't solve my problem.
Actually, I checked the data with respect to my theory 2 again, and I
must say: Visually it seems, that in this case the two data sets I would
like to overlay match perfectly concerning the boundaries. The theory
might be wrong.
I did some further testing:
Even if I isolate the polygon that disappears in the overlay process
v.extract input=veg output=veg_137 list=137
and use it for the overlay
v.overlay ainput=plot atype=area binput=veg_137 btype=area operator=and
output=res_137_and
the result is erroneous. Nothing new, but still very strange.
Tricky. I am puzzled and need to get home;-)

Falko,
I agree - the same error reproduces for me, using your vectors.
Neither veg nor plot show any apparent errors in v.digit.
Anyone offer suggestions to try and debug this?
Richard
