Hello, Please make sure ArcGIS Server Manager Service (window service) is started. When restarting ArcGIS Server make sure this service should be started after staring the ArcGIS Server Object Manager Service.

Hello, I need to find several things about my junctions and add that info as columns in the junctions table. One of them is the number of edges a junction connects to. From reading around I figured that there is a way to query the network dataset about that information but only programatically. Is that correct? In this case, I can work around this by doing a spatial join between my junctions and my edges and I get a count column which is what I want. The other thing is more problematic. I would like to have information about the class of edges a junction is connected to. Class is a column in my edges table. The only way to do this I can think would be to encode my classes as powers of 10 (residential = 1, secondary=10, major = 100, motorway = 1000, ...) and do a sum in the join so that if a junction connects to two secondary and a residential it would return 21 and I can also work the thing backwards (since there is a maximum of 8 edges connected to a junction). Is there a simpler way of doing this? Thanks, Guillaume

Hi Doug and thanks very much for your reply. I am new to ArcMap and was unaware of the issue of multipart geometries. One thing which I find hard to explain though is that it was working as expected on a larger dataset. This one was derived from it by doing an intersection. Could this have transformed some single part lines into multipart ones well within the intersection polygon? And from what I read these multipart lines cannot share a common point so that would mean that they are physically separated? I would like to dig into this a bit more but I am unable to find a tool that would allow me to inspect my features to understand what their parts are. I found some page about using the "data reviewer" extension but I don't have access to it right now. Do you know of any other way I could get a grasp on the single/multi part aspect of my features? Thanks again for your help, Guillaume I have been trying to understand this with the tool Multi to Single (this is the only way I have found to find out if a line is a multipart or not - by examining the output of the process) and what I found is that indeed, intersecting my feature class of single lines does produce multi-lines. Doesn't make much sense to me but there must be a good reason for that. It does explain my problem completely though. I will have to find another way of filtering my features that doesn't break things into multiple parts. Thanks again, Guillaume

A network dataset can only be created inside a feature dataset. So you need to create a geodatabase, then a new feature dataset (and set it's spatial reference to the streets feature class) and then import or copy all the feature classes into the feature dataset. Now you should be able to create the network dataset. The reason it needs to be in a feature dataset is so that all the sources making up a network should have the same spatial reference. Jay Sandhu Hi Jay, Following your instructions, I have managed to use a field of my own making as a cost in my junctions layer. Thanks very much again for your help. Guillaume
