[GRASSLIST:799] Automatic creation of Areas (polygons) from connected lines

[tlaronde at polynum.org]

Hello,

I suspect the question has already been asked, but I didn't
find an obvious answer.

Given a vector file with a correct topology (all lines are
connected and broken at nodes) is there a "magic" modules
allowing the creation of areas (parcels) from this vector
file? [to go the raster way is not an option here due to the
precision and hence the size of the resulting file]

Thanks for the help!
