[GRASS-user] limit Voronoi or other vector programs

[Maris Nartiss]

Hello,
currently there is no MASK support for vector data. Only solution is
to extract a subset of whole dataset into new vector map/layer with
existing GRASS tools (i.e. v.extract and others).

Also MASK concept for vector data is easy to implement for vector
points but it gets tricky with lines/areas. What should happen to
line/area that crosses MASK border?
Also as MASK normally is applied "on fly", it could be real show
stopper when working with large datasets (i.e. LiDAR data).

WBR,
Maris.
