About my situation: I've got a river network, which
is a polylinefeature set with 43 lines (43 IDs) included (tree-like shape of a
rivernet)
all with the same cat-value (1).
Now I would like to unite/merge the lines to one feature (1 ID) if that is
possible
and break that single element at given points with v.edit...Because if I break
now at around 40 positions I get over 80 segements (40 old segements and which
are broken again at different positions) but there should be only
41 or so...
so how can I handle that and assign unique cat values for each segment...(at the
moment the don't have to be the same like the breakpoints, just unique values)
any suggestions?
v.edit tool=catadd id= ?
