Hi list! I couldn't find an easy way to merge connected stream lines per network (stream output from r.watershed thinned and converted to vector). I'm not even sure if stream lines with tributaries can be merged into one feature. v.build.polylines merges multiple continuous lines, but it starts a new line at a confluence. If merging multiple lines with shared nodes is topologically impossible, what would be the best way to select all connected line features or assign the same category to those lines?
Any suggestions are welcome! Thanks! Huidae
