Esri Data & Maps - Which of 3 Data file contains prebuilt network dataset?

[MapzArthur]

Which of the three download files for "Esri Data & Maps for ArcGIS 10" contains the free network dataset called "Streetmap_na?"

Please see this link:

I want to use it to build a network layer for an origin-destination cost matrix. I'd rather not create my own.

Thanks!

There should be a file called "streets.rs" that will show up in catalog as a network dataset. The actual network files that it points to are in a folder called streets.rsx

Are these the two correct Network Datasets and are all the necessary files in the streets.rsx folder from the 10.1 Customer Care Download? (Please see attached PDF)

When I try to Preview the two SDC Network Datasets in ArcCatalog or add them to an MXD, I get the message - "Open Failed" Error Opening network dataset - is the "streets.sdc" dataset supposed to be referenced also?

Any advice or assistance would be appreciated.

the file structure does not seem to be right. Normally all the data resides in the streetmap_na\data folder.

In your first screen shot, you have the streets.sdc and the streets.rs files sitting at the same level as the streetmap_na
and then in the second screen shot the streets.rsx is in the streetmap_na\data folder.

Move the streets.sdc and .rs files into the streetmap\data folder.

Jay,

Thanks for your advice - by moving the files into the locations you described, I'm able to view them in ArcCatalog and add to an MXD.

When I tried to copy and paste the .rs files using ArcCatalog, it would not allow me to paste, so I used Windows Explorer. Is this a reason for this or is there a property setting in ArcCatalog that needs to be changed?

Also, what is the difference between streets.rs and streets4.rs?

Not sure why ArcCatalog did not let you move the files.

The streets.rs and street4.rs expose hierarchy into two different ways for the hierarchy On option in the route and other solvers.

The streets.rs has fewer roads on the top level hierarchy and will give you fast performance. But in some cases it can give you longer paths in areas of the country that has a very sparse highway network. So if you start to see "longer" paths then use the streets4.rs
Again, this is an issue with the free Streetmap data as it not the most up to date premium content. The Streetmap premium has lot more details and better defined hierarchy and only has one .rs file.
