Split polyline features at points in ArcGIS Pro

Summary

In ArcGIS Pro, polyline features with points can be split at the points using the Split Line at Point tool. However, it is sometimes necessary to integrate the polyline and point features together using the Pairwise Integrate tool before splitting the polylines. The Pairwise Integrate tool collocates the two features together to yield better results.

This article describes the workflow to split polyline features at the points by integrating the features together with the Pairwise Integrate tool and using the Split Line at Point tool to split the polyline features. In this example, the polyline feature highlighted in blue is to be split at the points.

Procedure

Note:
The Split Line at Point tool requires an Advanced ArcGIS Pro license.

1. Open the ArcGIS Pro project.

Note:
The Pairwise Integrate tool permanently modifies the input data. It is recommended to create a backup copy of feature layers.

2. Create a backup copy of the polyline and point feature layers using the Copy Features tool.
   1. In the Geoprocessing pane, search for and select Copy Features (Data Management Tools).
   2. Under the Parameters tab, for Input Features, select the polyline feature from the drop-down list. In this example, 'Water_Main' is selected.
   3. For Output Feature Class, specify the output location.
   4. Click Run.

5. Repeat Steps 2a through 2d using the point feature as the Input Features. In this example, 'Pipe_Feature' is selected. The newly created 'Pipe_Feature_2' and 'Water_Main_2' feature layers are added to the Contents pane.

3. Integrate the polyline and point features together using the Pairwise Integrate tool.
   1. In the Geoprocessing pane, search for and select Pairwise Integrate (Analysis Tools).
   2. Under the Parameters tab, for Input Features, select the feature layers created in Step 2 from the drop-down list. In this example, 'Pipe_Feature_2' and 'Water_Main_2' are selected.
   3. Click Run.

4. Split the polyline features at the point using the Split Line at Point tool.
   1. In the Geoprocessing pane, search for and select Split Line at Point (Data Management Tools).
   2. Under the Parameters tab, for Input Features, select the polyline feature to be split. In this example, 'Water_Main_2' is selected.
   3. For Point Features, select the point feature in which the location is used to split the input polyline feature. In this example, 'Pipe_Feature_2' is used.
   4. For Output Feature Class, select an output feature class to store the split lines.
   5. For Search Radius, specify a value in the first field. In the second field, select the unit of measurement. In this example, '10 Meters' is specified.
   6. Click Run.

The polyline features are split at the points.
