Location XY is on a non-traversable network element position. Warning: 0 location(s) in "Incidents" are valid. Need at least 1 valid location(s). Warning: 0 location(s) in "Facilities" are valid. Need at least 1 valid location(s). Error: Insufficient number of valid locations in "Facilities" or "Incidents". Your Incidents and Facilities are on street elements that are either not connected to the rest of the network (for example because of little gaps from the endpoints to the next street elements), or there are some restrictions active that prevent using this street (use the network identify tool to check, or turn restrictions off in the analysis settings). My minute Field rows are all null value, how can I calculate this to return figures? For example with the field calculator and a little math using a speed value (30mph?) and the shape length attribute.

Still looking for answers... I found out, that the merging of data seems to be the problem. When I create the Network Dataset out of the individual NAVSTREETS regions everything works fine. But I want one big Network Dataset, so I merged the relevant feature classes (Streets, Zlevels, CDMS- and RDMS-tables, ...). Running the tool with these as input, I get the error message (see above). Makes me wonder how I need to treat the turn restriction information, as I believe that's where the trouble starts.

I am not familiar with the OSM data quality of the London area, but when I used OSM Data from Hamburg with the Network Analyst I for example had problems with oneway streets (editing needed for ArcGIS to recognize them properly), prohibited turns onto highways (missing z-levels, bad connectivity set-up) and maxspeed data (many values not existent). Not being able to perfom some types of analysis like Closest Facility seems rather odd though. What exactly happens when you try to do that?

When trying to process some rather large NAVSTREETS Data using one of these Street Data Processing Tools, I encounter an error I don't find a solution for myself: Creating and building the network dataset... Network object evaluator error. at ESRI.ArcGIS.Geodatabase.INetworkBuild.BuildNetwork(IEnvelope areaToBuild) at GPProcessVendorDataFunctions.ProcessNavStreetsDataFunction.CreateAndBuildNetworkDataset(String outputFileGdbPath, Double fgdbVersion, String fdsName, String ndsName, Boolean createNetworkAttributesInMetric, Boolean createTwoDistanceAttributes, String timeZoneIDBaseFieldName, Boolean directedTimeZoneIDFields, String commonTimeZone, Boolean usesHistoricalTraffic, ITrafficFeedLocation trafficFeedLocation, Boolean usesTransport) at GPProcessVendorDataFunctions.ProcessNavStreetsDataFunction.Execute(IArray paramvalues, ITrackCancel trackcancel, IGPEnvironmentManager envMgr, IGPMessages messages) Failed to execute (ProcessNavStreetsData). During the processing up to this point I got a few warnings like: ERROR: Edge 2 is discontinuous with the previous curve! Turn OID : 29759 But I don't know if this is relevant. Any help/suggestions would be highly appreciated. Thank you!
