Hi list,
I'd like to have a little help.
I have an area vector where the single areas have a category value link to the
centroid. I'd like to extend the centroid value to the boundaries of the
polygons.
There is a command for that?
regards
Leonardo

v.to.db option=sides
?
If areas touch it can be ambiguous as to which area will supply the
boundary category. I have a method buried somewhere; try searching the
mailing list archives for something by me ~5 months ago on doing this.
(try "coastline length" as a keyword in that search)

Thanks Hamish,
good solution for a new command in GRASS...
regards
