Creating a network analysis layer in ArcMap
- Start ArcMap by clicking Start > All Programs > ArcGIS > ArcMap 10.
Add a network dataset to ArcMap if you don't already have a network dataset layer available in the table of contents.
- If you have more than one network dataset in ArcMap, click the Network Dataset drop-down list on the Network Analyst toolbar and choose the network dataset you want to perform the analysis on.
On the Network Analyst toolbar, click Network Analyst and choose a network analysis layer to create.

Network analyses are always performed on network datasets. Consequently, a network analysis layer must be bound to a network dataset.
A network dataset needs to be added to ArcMap before a network analysis layer can be created. When an analysis layer is created, Network Analyst automatically binds it to the active network dataset.
The active network dataset is displayed in ArcMap on the Network Dataset drop-down list, which is on the Network Analyst toolbar.
The new network analysis layer appears in the Network Analyst window and is bound to the active network dataset. The network analysis layer also appears in the table of contents as a composite layer.
