Using the Identify LRS Route Locations tool
The Identify LRS Route Locations tool is accessible from the Roads And Highways Editing toolbar and is used to discover measure value information from LRS Networks. You can use this tool to discover m-values from interpolated linear referencing methods (LRM) or offsets from referent locations. See Advanced linear referencing—Multiple linear referencing methods to learn more about LRMs.
Clicking the Identify LRS Route Locations tool and clicking a map location displays the Identify LRS Route Locations dialog box. This dialog box shows information about the route features available in the map.
Allows you to view information about a single route layer.
