Removes overlapping centerline sections to ensure that there is one common centerline in cases where centerline geometry overlaps.
The ArcGIS Location Referencing minimum schema models route concurrencies by having routes share the same centerline associations in the centerline sequence table. Running this tool may result in centerline changes, such as centerline splitting or deletion of duplicated centerline features. It may also update centerline sequence table records so that routes share centerlines.
Overlapping centerlines can result when any of the following occur:
While the Remove Overlapping Centerlines tool can be run any time after a LRS Network is created and data is loaded, consider running it only after you've finished creating all LRS Networks and have loaded all data in your LRS. If additional columns are modeled on the centerlines, some centerline attributes may be lost when the tool is run.
An LRS dataset is required to run this tool. To create an LRS dataset, add the calibration point, centerline, and redline layers to a feature dataset; then run the Modify LRS tool with the geodatabase as the input.
The number of centerline features in the input centerline feature layer may be different after running the tool, depending on the number of overlapping centerlines and the routes associated with them.
This tool uses the topological operations Intersect and Simplify in conjunction, which can cause small polyline segments of a length around and above the feature class tolerance to be lost. Associated route shapes may change slightly beyond tolerance as a result of using this tool. Consider starting an edit session in ArcGIS Pro for test runs of the tool using the Enable Undo button in the Geoprocessing pane. For more information about how cluster tolerance is used in ArcGIS topological operations, see Understanding Geometric Processing in ArcGIS.
This tool ignores z-values on the centerlines during its calculations. For example, if two centerlines do not overlap in 3D space but do overlap in 2D, they will be considered overlapping by the tool.
