描述
Modifies an existing linear referencing system (LRS) in the specified workspace.
使用方法
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.
