Hi,
I am trying to build a network using the OSM roads dataset.From this i would like to extract all roads within a set distance from a point.This should not be a simple as the crow flies buffer selection but by road distance on each road from the point.
Thoughts?
I'd recommend validating the network first.All the FME network transformers assume that the network is clean.All intersections are fully noded and junctions occur at endpoints,not mid-point vertices.Use the NetworkTopologyCalculator to help validate the network and look for segments that do not connect
@lemziphave a look at the NetworkCostCalculator transformer.Set the Weight Type By Length and output cost by Z value.Then test the Z values for your distance.
