I found the following post of yours and wanted to find out some more detail in how to performed the following. I've got a similar problem that i'm trying to solve. I've got land parcels that have been identified as users for effluent reuse water for irrigating parks, sports fields and green belts. I want to use the road network to determine the optimal layout of my pipeline network using the parcels as stops. I can easily convert my parcels to points if need be. I wanted to find out from you in more details how to solved your problem using MST, Network Analyst to generate you network.
Thank you Dan, actually it is only for point-input layer while I am looking for minimum spanning tree tool that can be applied on a specific road map (a network with points and lines).
yes... it isn't designed for that specifically, but can work if the road can be converted to points and the inter-road spacing is greater the along-road point spacing... that is, so that the spanning tree doesn't hop from one road to another. sometimes, you can ensure point-along-line traverse, by densifying the points on the network. You will have issues if the point data set is large, since that incarnation hasn't been optimized (on the todo list)
strange... did you unzip everything in the same folder? and add the toolbox to arctoolbox?
If there are bits missing Lano, Let me know and I can fix the update in about 8 hours (not on, or near my 'machine' sorry)
