I have been looking for ways on how to compute the shortest distance between one point to multiple points using a specific road network.
I have not been successful in achieving the solutions in this site.
Here's my case:
I have 3 shapefiles: 1. Road Network (lines) 2. Polygon Centroids 3. Source Point (Starting Point)
How do i easily compute the shortest distance between the starting point to the polygon centroids over the road network?
