Modify LRS (Location Referencing)

Summary

Modifies an existing linear referencing system (LRS) in the specified workspace.

Usage

• The Modify LRS tool can be used on a feature class or table with or without geometry or records.

• The route ID and centerline ID must be unique; however, the tool does not check for duplicate IDs.

• This tool does not check for erroneous network IDs; if the network ID does not exist, it is considered erroneous.

• For more information about configuring the LRS and field properties, see the ArcGIS Pipeline Referencing LRS data model or the ArcGIS Roads and Highways LRS data model.
