Dear Konrad,
I
don't know any functionalty in gvSIG or SEXTANTE that makes what you
need. Maybe with some workaorunds (e.g. v.extract), time and batch processing
files in SEXTANTE you can get what you want. In SEXTANTE (with Grass GIS and
SAGA) you
will find a lot of functionalities for raster and vector layers.
The functionality you are describing is a typical one for the SEXTANTE toolbox
and isn't difficult to develop. It will make the SEXTANTE toolbox even better.
Maybe someone would like to develop it or could consider the possibility to
hire a developer to create this new option. In the SEXTANTE user list you will
find more help.
Best regards
Jose
