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.
Thanks, Dave -- ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ David W.
