NETWORK BUILDING IN ARCMAP
The first build process on a new network dataset creates network elements, establishes connectivity, and assigns values to the network attributes based on the properties you defined in the New Network Dataset wizard. Also, a point feature class containing all the system junctions is created in the workspace that contains the network dataset. Geodatabase network datasets can be built inside or outside of an edit session; however, shapefile network datasets must be built outside of an edit session. The following steps expains the procedures you follow in ARCMAP to build a network dataset: Start ArcMap. Click the Catalog window button on the Standard toolbar. The dockable Catalog window opens. Using the Catalog window, navigate to the location of the network dataset and drag it into the map display or the table of contents. If a connection to the folder that contains the network dataset doesn't already exist, you can create one by clicking the Connect To Folder but
