Hi List, I'll need to perform some network analysis and right now I'm trying to see if my roads map is all good. I know that there are some clearly isolated areas on my roads network but I'd like to identify and fix the less obvious ones.
Here is what I did: 1) Import road lines (v.in.ogr) 2) Clean the topology with snap tool, thresh=0.0001 (it's a latlong location) 2) Create network (v.net using the nodes option --not sure if that was the correct option) 3) Ran v.net.components to find the weakly connected components, not setting any cost columns 4) Color roads lines according to the component number By doing that I could spot the lines that were clearly disconnected (net_components_unlink.png). But I also found some lines that where disconnected even thou there are nodes (red squares) linking them (apparently) - net_components_pseudo_link.png Should I increase my snapping threshold? How can I see if my nodes are endnodes or located between two lines? Thanks Daniel
