topic Error using OD cost matrix as CSV executable. in ArcGIS Network Analyst Questions https://community.esri.com/t5/arcgis-network-analyst-questions/error-using-od-cost-matrix-as-csv-executable/m-p/17661#M207 <HTML><HEAD></HEAD><BODY><SPAN>I am calculating the travel time and distance between a series of points using the OD cost matrix solver in the Network Analyst extension. I have a large number of Origins and Destinations so I batch processed the solver using the "Network Analyst Origin-Destination Cost Matrix as CSV" created by Patrick Stevens and found at this link. </SPAN><A href="http://resources.arcgis.com/gallery/file/ArcObjects-.NET-API-Code-Gallery/details?entryID=779B6061-1422-2418-7F22-D8721D17FBFB">http://resources.arcgis.com/gallery/file/ArcObjects-.NET-API-Code-Gallery/details?entryID=779B6061-1422-2418-7F22-D8721D17FBFB</A><BR /><BR /><SPAN>My issue is that I get different results when using the solver in ArcMap as compared to the executable file above. The difference is that for a subset of the data the executable file produces no results for every combination of origin-destination while the solver in ArcMap produces the distance and time for some of the origin-destination combinations. </SPAN><BR /><BR /><SPAN>As far as I can tell I am putting the exact same data set into each process. I add my origins and destinations to the OD-Cost Matrix layer and save it as a layer and use the command line to run the executable file. I use the same layer in ArcMap and select solve which produces different results. </SPAN><BR /><BR /><SPAN>I would expect some combinations of origin-destinations to be non-routable, as they are on islands. But this doesnt explain why the executable file fails to calculate the distance and time between the combinations that are routable. I dont know where to begin to troubleshoot and determine where the error occurs with the executable file. Any suggestions would be greatly appreciated.</SPAN></BODY></HTML> Mon, 02 Apr 2012 16:26:36 GMT KyleHubbard 2012-04-02T16:26:36Z Error using OD cost matrix as CSV executable. https://community.esri.com/t5/arcgis-network-analyst-questions/error-using-od-cost-matrix-as-csv-executable/m-p/17661#M207 <HTML><HEAD></HEAD><BODY><SPAN>I am calculating the travel time and distance between a series of points using the OD cost matrix solver in the Network Analyst extension.
