Hi, I'm working with an SDC network dataset contained in Data and Maps for ArcGIS (2013) I downloaded on MyEsri. I was under the impression that this prebuilt network dataset can be used for network analysis. However, when I load the dataset (street4.rs) and all the feature classes it contains, I'm only seeing Edges, and not Junctions. It contains a 'SDC Junction Source' but a junction feature class is missing.
I've realized that a network dataset needs to be 'built' in order to create 'a point feature class containing all the system junctions'. However, I also came across the following information: 'SDC-based network datasets cannot be built'.
My goal is to compute intersection density using a network dataset (ideally a prebuilt one as I need to compute it for the entire contiguous US)
In light of all of this, I would like to know:
- Can I still somehow create junctions using this prebuilt network dataset to compute intersection density?
- If the prebuilt network dataset cannot be built and used to establish connectivity, what are its capabilities/what is it good for? For example, can I use it to find & save the shortest distance between two destinations?
I'd appreciate any help, thank you!
