Hi Jay, I have a follow up question. I notice that once I have created a OD Cost Matrix, in the attributes table of the lines, the OriginID and DestinationID does not carry over. But I do find out in the OD Cost Matrix properties, under the Network Locations tab, that we can change the Candidate Fields in Network Location Field Mapping. I am just wondering is there any documentation that I can refer to if I want to customize my Lines JOIN? Thanks!

Thank you so much for your help, Jay and Deelesh! I have another question though. I am using OD Cost Matrix for my task and I find out once you load your locations into either origins and destinations, they are assigned new attributes, which have nothing in common with the original points. I am just wondering is there any way I can keep some if not all attributes from the original point layer. I know on the map, they are two separated layers, I am thinking I could use spatial join, but I am afraid it would not help much.

Thanks for replying Jay. That was the method I have been using. I am curious if I can create a network dataset without any street data. Say, I have 4 points and I have their lat/long, all I want is the 6 straight lines between these 4 points. Also, is there a way I can convert point to polyline? Thanks,

Hello, I have a question regarding what feature classes to include in a Network Dataset. I know the feature classes in the feature dataset need to have some kind of time/distance as the cost/measure and they need to be edge sources. I am just wondering if this is possible: If I want to create a OD Cost Matrix analysis layer, all the data I have are the Lat/Long of points and the relationships between the origins and destinations. 1. I can use a road/street shape with a time/distance field This is definitely plausible, my only problem is that this shape is too detailed (Is it possible to use a very simple road/street shape?) 2.Can I use a polyline shapefile and join it with a table that contains the relationships between the origins and destinations? All I really want is just lines connecting points together, and I have an ArcEditor license. Any help is greatly appreciated.
