Hi
I am in need of some assistance. I have a traffic link network,
composed of a polylines.
I want to identify all the links within 200m of a location. I then
need to know, for each identified link, if it is connected to any of
the other links identified. Ideally, i need this to be automated
because i need to repeat the process for many thousands of locations,
and the output added to a field(s) associated with each location.
For example, in the diagram below assuming all these links are within
200m i need a list which shows that:
1 is connected to 2 & 3
2 is connected to 1, 3 & 4
3 is connected to 2 & 4
4 is connected to 2 & 3
5 is connected to 1 & 2
3/

All help much appreciated!
Thanks
