Update by Alternate ID Fields (Network Analyst)

ArcGIS Pro 3.4 | | Help archive

Summary

Updates all the edge references in turn feature classes using an alternate ID field to identify the corresponding edge features for each turn. Use this tool after making edits to the edge source feature classes that alter ObjectID values.

Usage

  • The Edge#FID fields in a turn feature class refer to the ObjectID of the line feature in an edge source in the network. However, ObjectIDs are system managed and can change during certain editing operations. To ensure that the turn features retain the correct reference to the edge features after this type of editing workflow, use the following workflow:

    1. Create and populate a unique ID field in each of the network's edge source feature class. Alternatively, use a unique ID field included in the data by the data provider, if one exists.
    2. Run the Populate Alternate ID Fields tool to create and populate a set of alternate ID fields (AltID#) in the network dataset's turn feature classes. The tool populates the alternate ID fields with the designated unique ID field values from the edge sources, linking each turn feature to the appropriate edge source feature through the alternate ID fields in addition to the Edge#FID fields.
    3. Perform the edit operations that may change the ObjectIDs of the edge sources.
    4. Run the Update By Alternate ID Fields tool to update the Edge#FID fields in the turn feature classes using the alternate ID field values to look up the ObjectID values of the corresponding edge source features.

Parameters
