Designing the network dataset

To model transportation networks, a network dataset must be thoughtfully designed. You can achieve this by following the four-step process discussed below.

Step 1: Select the source workspace

A network dataset can be created within a geodatabase or shapefile workspace, or it can reside in an ArcGIS StreetMap dataset. A shapefile network dataset supports one edge source, while a geodatabase network supports multiple edge and junction sources. An ArcGIS StreetMap dataset is a highly compressed countrywide street network that can be used for network analysis.

Step 2: Identify the sources and the role they will play in the network

Step 3: Model connectivity

Connectivity can be established for a network dataset using the ArcGIS Connectivity model in conjunction with the elevation field model.

Step 4: Define attributes and determine their values
