but why are there two 1's after the 'C' for centroid?
Ah, the number of categories.

Thanks very much. It's also on the 7.7 manual page, but it hadn't registered

If you want to go straight from the point coordinates to a polygon, you
can use the GRASS standard ASCII format and pipe directly to v.in.ascii:

I wondered about that.

I don't remember the workflow converting corner points into an area and find
no saved example here.
When I try the sequence:
v.to.lines in=anal_corners out=anal_bnd
v.build map=anal_bnd opt=build
v.centroids in=anal_bnd out=anal_area
grass tells me 'input vector map contains no boundaries'.

Markus M,
Sigh. Obviously, yes. And I completely missed seeing this. I knew it was
something simple that I overlooked.
Thank you very much,
