Modifying elevation field connectivity
- Open the Network Dataset Properties dialog box.
- Click the Elevation tab to examine and modify elevation field connectivity.
- To change the field used to provide elevation data, click under the Field column and click the correct field from the drop-down list.
- Click OK to close the Network Dataset Properties dialog box.
- In the Catalog window, right-click the network dataset and click Build.
The only fields that are available in the drop-down list are those with an integer data type because elevation levels are specified by integers. Any integer value is valid; that is, the field you choose can have positive, negative, and zero values.
The network must be rebuilt to reestablish the connectivity, recalculate affected attributes, and update the network elements.
