Populate Alternate ID Fields (Network Analyst)

This ArcGIS 2.8 documentation has been archived and is no longer updated. Content and links may be outdated. See the latest documentation.

Summary

Creates and populates additional fields on the turn feature classes that reference the edges by alternate IDs. The alternate IDs allow for another set of IDs that can help maintain the integrity of the turn features in case the source edges are being edited.

Usage

  • The tool creates and populates new fields called AltID<n>, where n is the maximum number of edges per turn. For example, for two-edge turn feature classes, the tool creates and populates fields called AltID1 and AltID2.

  • Shapefiles do not have a persistent unique identifier, unlike the geodatabase's ObjectID field. Alternate IDs can avoid the ID shift problem commonly encountered when working with turn feature classes in a shapefile workspace.

  • If the edge feature sources do not have an alternate ID field, for example, a unique identifier provided by a data vendor, then you must create and populate such a field so that it can used by this tool to reference the turn features.

Parameters

LabelExplanationData Type
Input Network Dataset

The network dataset whose turn feature classes are to receive alternate ID fields. The fields will be created on all of the turn feature classes added as a turn source to the network dataset.

Network Dataset Layer
Alternate ID Field Name

The name of the alternate ID field on the edge feature sources of the network dataset. All edge feature sources referenced by turns must have the same name for the alternate ID field.

String

Derived Output
