The dataset is the Harmonized World Soils Database. I've updated the wiki with
correct instructions. I think they're correct, at least.

After reading your first post, I tried
on a small contrived sample of polygons and points. I moved the
polygon centroids to "un-natural" positions, to try to get the
wrong values uploaded to the points attrib table. The bottom line
was that v.what.vect seemed to w
Hi again,
I'm still struggling with how to add the attribute values from a polygon map to
the table for a point map. I've tried v.what.vect, as documented in my previous
message. Any suggestions would be appreciated!
Thanks,

Hello,
I have a vector point map, amelanchier, and a vector polygon map,
