I am using Network Analyst OD Cost Matrix to calculate the distance between a number of locations in dataA and a number of locations in dataB.

I wonder how to change the network used for these calculations. The default under Network Analysis -> Network Data Source is arcgis.com. I assume that the Input Network Analysis Layer is where I choose along which network the distances should be calculated. By default, it says OD Cost Matrix.

I have my own road map that I would like to calculate the distances along, in shp-format. I have added this to my map, so I can see the roads. But I cannot figure out how to use this as th network in OD Cost Matrix calculations.

First of all You should build network dataset, based on your roads. After this step You will be able to calculate OD matrix.

  • Thanks for the hint! And a network dataset is possible to build from a road map in shp-format that I read in to ArcGIS?

  • You can do it from shape file. But for better result, your data must be topologicaly valid. Topology class can be built only in geodatabase. To build a ND, you need a Network Analyst license and a data in a specific format - you need a description for oneway roads, connections, turn restrictions. If You need only to create a simple geometric network, or walkaway-like network, you can create a ND with default parameters and 'any point' as a connection.
