The Build Geometric Network wizard discovers the connectivity for a group of feature classes in a feature dataset and promotes them from simple feature types (lines and points) to network feature types (edges and junctions).
When you build a geometric network, the feature classes must already exist in the feature dataset. However, they can be empty. After the network has been built, you can add new network feature classes.
Geometric networks are built in ArcCatalog.
- Right-click the feature dataset that will contain the network.
- Point to New.
- Click Geometric Network.
- Read the information on the first panel and click Next. If you don't want this screen to appear every time you create a new geometric network, click the checkbox for Skip this screen in the future.
- Enter a name for the new geometric network or accept the default name.
- Specify whether snapping should occur during geometric network creation and set the snapping tolerance. The default value will be set to the x,y tolerance of the feature dataset.
- Click Next.
- Click the feature classes that you want to include in this geometric network.
- Click Next.
- If all of your feature classes contain coordinate z-values, you can choose to have the connectivity based on x, y, and z values and can choose to set the z snapping tolerance. The z-tolerance (0.001 meter in real-world units). Choose Next to use z-values for connectivity or choose No and click Next to not use z-values for connectivity.
- If any of the feature classes selected to participate in the network contain an enabled field, you can choose to keep the enabled values or reset them to true. Click No to enable all network features. Otherwise, Persist enabled values is selected by default.
- Click Next.
- Click the dropdown under Role and specify if any of your feature classes should be Complex Edges, otherwise, accept the default of Simple Edge.
- Click the dropdown under Sources/Sinks for any junction feature class to act as sources or sinks for modeling flow direction. Otherwise, accept the default of No and click Next
- To add a new weight, click New.
- Type a name for the new weight, click the drop-down arrow, then click a weight type and a size for bitgate weights. If the name of the weight matches the name of any fields in the feature classes, the field will be automatically associated with the weight. Click Ok.
- Click the dropdown under Field for each feature class you want to associate the weight with and select the Field. Only fields matching the weight type will be displayed.
- Repeat the previous two steps until all the network's weights have been defined.
- Click Next.
- If your geodatabase is stored in an ArcSDE geodatabase and you have a configuration keyword for the network stage, click Yes and choose the keyword from the dropdown menu. If not, skip to step 21
- Click Next.
- Review the options you specified for your new network. If you want to change something, you can go back through the wizard by clicking the Back button.
- When satisfied with your options, click Finish to create the new geometric network.
