Modify LRS (Location Referencing)

Summary

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

Usage

• This 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.

• Learn more about configuring LRS and field properties in the ArcGIS Pipeline Referencing LRS data model or the ArcGIS Roads and Highways LRS data model.

• The Realign Overlaps rule for event behavior supported in Roads and Highways in ArcMap is not supported in ArcGIS Pro.

  If event behaviors were configured in ArcMap using the Realign Overlaps rule, substitutions will be made using comparable Realign event behavior values.

  This tool will check for conflicting Realign and Realign Overlaps event behaviors and will support Realign event behavior if Realign Overlaps event behavior is encountered. This tool does not support Realign Overlaps event behavior.

  Note:

  The Snap option supported in ArcMap is supported for Realign event behavior in ArcGIS Pro 2.9 or later.

  The following table lists the resulting value in ArcGIS Pro for configured Realign and Realign Overlaps event behavior in an LRS migrated from ArcMap:

  If Realign in ArcMap is	And Realign Overlaps in ArcMap is	Realign in ArcGIS Pro will be
