No, Grass is a topological GIS, that is adjacent polygons share a single
common boundary...
You can digize a layer of boundaries, then create the polygon topology
with v.build.
Good luck,
Vincent

Hi,
I am using grass digitisation tools and wants to know wether it is
required to redigitise the common boundaries between the adjacent
polygons. Also let me know how to add islands, merge two polygons into
a single polygon.
Thanking in advance
