I'm working on food poverty in rural Germany and got stuck. I want to look at all the residential houses of a municipality area and find out where the closest supermarket is located. If one cannot reach it by a 15 minutes walk, I will expect that the local supply is not assured.
So far, I have created a network dataset with all the roads, bikeways and junctions of the municipality area. However, I cannot run the Closest Facility Analysis. I guess, this is because I have not connected the building / supermarket coordinates to the network data set - but I don't know how to do this. Can someone help me out?
