Hello
Thanks for the advice.
The first step suggested does produce a new vector map with the old
information in layer 1 and new categories in layer 2 (nothing else).
However, I do not understand the 2nd step. Do you really mean to connect
table2 (I guess that is the one belonging to map2) to
Does this helps you?
v.category input=map_of_vedit output=map2 option=add layer=2
v.db.addtable map=map2 layer=2 table=table2
In that way you preserve original information in layer1, and new categories
in layer2
Hopefully that will be useful. Maybe someone has a better idea.
