Hi Moritz
Thanks for the heads-up! Yes, for overlapping buffers v.rast.bufferstats
seems just perfect! IIUC, it does exactly what MM was explaining. Great!
Thanks again! And thanks Stefan for the add-on!

Hi Markus,
Thanks for the explanation. It is possible to import topologically
incorrect vectors, but not create them within GRASS. So, as a solution to
my problem, I rather create (potentially overlapping) buffers outside GRASS
and import them with -c in v.in.ogr to use v.rast.stats with no loss

Dear all,
thanks again for your answers. I found an easier way, use -c flag in
v.in.ogr seems to not build topology of overlapping areas and then
v.rast.stats does not complain.
However, if one builds buffer areas for points within GRASS, i.e., using
v.buffer, the problem appears again when

@Madi, I know, but that's how I got the data from a colleague using
SaTScan to get cluster sizes.
So, these "clusters" are 3, they are represented by circular areas and 2
of them overlap, and it is just fine that

Ciao Vero,
shapefile is not a good choice in this case for exporting such geometry
because is not apt to store topological information. You may want to export
your dataset in a different format, e.g. geopackage.
Hope this helps,
