Hello,
as it seems that there was something wrong with my post yesterday I
send it
again (if everything was ok already yesterday, sorry for double
posting):
For a certain application I need to transform a river from the
raster format into the vector format and vice versa.
I'd like to know how good does it work to tranform a line
feature from vector into raster and back again into
a vector? Is there any "stable" line which doesn't
change anymore after x-times transforming back and
forwards? I haven't had time to test it but I thought about:
v.to.rast
r.thin
r.to.vect
this should result in a "stable" line or does it
need several iterations?
Has anyone tested such things and can share the experience?
Probably it depends on the resolution and the
shape (bends etc.) of the line vector...
Maybe there is already a tool out which generalises, produces
and tests a "stable" raster-vector-line.
Any hints and suggestions are mostly welcome...
best regards,
Johannes
