| Jul 5, 2013 at 19:02 | comment | added | David Giacomin | Thank you this is exactly what was desired. I have run into a slight problem with edge behaviour. Many times I will be dealing with small networks that may have as few as 10 nodes, and I must calculate for a distance beyond the extends of the network. With the Euclidean Distance function, how may I include distance calcuations for the points that lay just beyond the extents of the outer points? (The 'maximum distance' field in the Euclidean Distance function doesn't seem to be helping.. | |

One can go even further and use a travel-time grid instead of a Euclidean distance grid: the procedure remains the same. | |
