Split a centerline by point

Available with Location Referencing license.

The Split Centerline By Point tool is one of the centerline feature class editing tools available in ArcGIS Pipeline Referencing. This tool is useful to split a centerline into two contiguous parts at a clicked location on the map to create a route that does not span a complete centerline. This tool is typically used to split a centerline relative to some feature being snapped to, such as an intersection, county boundary, or railroad crossing.

Pipeline Referencing also supports splitting a centerline using a measure value or splitting a multipart centerline into singlepart features.


You can also use the Split tool on the ArcGIS Pro Edit tab to perform this task. However, if the centerline has z-values populated, it is recommended that you use the Split centerline by point tool on the Location Referencing tab.

  1. Add the centerline feature class and network feature class to a map.

    You can also open a map in which the centerline and network feature class are already present.


    The information model expects only one centerline at any given location. Ensure that the centerlines used for your edit do not overlap other centerlines in your LRS.


    Traditionally versioned networks must be edited through a direct connection to the geodatabase. Branch-versioned networks, including any network configured with a user-generated route ID, must be edited through a feature service.

  2. Zoom to the centerline that you want to split.
  3. On the Location Referencing tab, click Split Centerline, and click the Split Centerline By Point button Split Centerline By Point.

    The cross pointer is employed while using Split Centerline By Point Split Centerline By Point.


    Place the pointer Cross Only over the location to display route and measure information on the map. The route and measure update as you move the pointer. If multiple routes and measures exist at a location, they are shown.

    If only one applicable route exists at the edit location, click to select it. If multiple routes are applicable, click to choose one of the applicable routes using the Select Route dialog box.

    You can set map scale options for display of route and measure information on the Options dialog box, on the Location Referencing tab.

    To search for a route and locate measures on it, click Locate Route and Measures Locate Route and Measures in the Tools group on the Location Referencing tab.

  4. Click a point on the centerline where you want it to split.

    The centerline on both sides of the split location flashes in dark green and the centerline splits into two parts.


    If additional fields are modeled on the centerline, attributes from those fields on the centerline being split are added to the new centerlines resulting from the split.


    If a message regarding acquiring locks or reconciling appears, conflict prevention is enabled.


    In a combined Utility Network and Pipeline Referencing deployment, if the centerlines with associated routes are split, the RouteID, From Measure, and To Measure fields of the centerlines are updated.
