[GRASS-user] to separate a polygon

[Vincent Bain]

Yvan,
could you please state your intention ? and clarify how your network is
represented : are roads delimited by polygon boundaries and crossroads
by nodes ? or was the network digitized as a polygon (I mean giving
roads thickness) ?

First, about data type conversion, you can have a look at v.type.

Yours,
Vincent.
