Hi List Trying to get my head around the easiest way to generate a contour map of travel times from a central location based on road centreline network.
We have a central location and need to generate polygons showing which properties are with 5, 10, 15 etc minutes of this location. A road network is present with estimated speeds along each segment so we can calculate estimated travel time along each segment. How do we go about traversing the networking and creating points at say 5 minute intervals, making sure we are travelling away from the central location. The idea was then to join up the points to create polygons and overlay over the property boundaries. Any ideas/help much appreciated. Simon
