Markus,
Thanks a mill! I'll try that when I get back to that machine.
I really appreciate you time end expertise. You're a scholar and a
gentleman.

I would suggest to run

Thanks Markus! Now I'm getting somewhere. v.info shows geo and new_geo in
perfect correspondence for areas, islands, boundaries, etc.
d.what.vect shows new_geo with the original data in layer 1 and the new data
in layer 2. v.to.db successfully transferred the centroids (coor) and area
to layer 2. However, I still don't see how to get the surficial geology
column (surgeo) out of layer 1 into layer 2 without a join item. I know I'm
missing something simple, but v.to.db just seems to allow a restricted set
of values for option.
v.to.db map=new_geo layer=2 column=surgeo option=query qlayer=1 qcolumn=surgeo
In this example, the column surgeo in layer 2 must exist and must be
of the same type like the column surgeo in layer 1.

Thanks, Dave
