[GRASS-user] Problems in adding tables to a map

[Martin Landa]

Hi,

it's not enough. You need to defined also categories for layer '2',
see `v.category` for details. This module allows to change layer
number, but unfortunately not to copy categories from one layer to
another.

Motion:

v.category input=roads1 output=roads2 option=cpylayer layer=1,2

to copy categories from layer 1 to layer 2 would make sense? It would
require to add new option `cpylayer` similarly to `chlayer`.
