Apply cartographic realignment

Location Referencing ライセンスで利用可能です。

You can update route geometry based on aerial imagery, as-built drawings, or input from field data collectors without changing measures by making direct modifications to the centerline. This is known as cartographic realignment. ArcGIS Roads and Highways allows you to change the shape of centerlines and preserve the calibration of the underlying routes as they existed before cartographic realignment.

注意:

The centerline feature class must be visible in the Contents pane to apply cartographic realignment.

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

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

   注意:

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

   注意:

   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 in to the location of the route that you want to realign.

3. Uncheck the network layer in the Contents pane.
4. Check the centerline layer in the Contents pane.
5. Select the centerline feature for the edit.
6. Double-click the centerline's edge.

   The selected centerline's vertices appear.

   

7. Edit the centerline's vertices as necessary.

   You can add, delete vertices, and modify segments. You can also use the geometry editing tools available in Roads and Highways.

   

8. After editing the vertices to match the proposed alignment of the route, right-click anywhere on the map and click Finish.
9. Check the check box next to the network layer in the Contents pane.

   The cartographically realigned route appears.

   

   注意:

   • After centerlines are updated, the route shapes in all networks are also updated. However, the event shapes for events and locations of the managed intersections are not updated until you run the Apply Event Behaviors and Generate Intersections geoprocessing tools.

   • It is also important to note that when the centerlines are edited, all routes in all networks, across all times, are modified accordingly.
   • If conflict prevention is enabled, locks will be acquired on all routes associated with the centerline being edited.

   注意:

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

Complex route cartographic realignment scenarios

The following sections provide examples of complex route cartographic realignment on loop and lollipop routes.

Cartographic realignment on a loop

In the following example, an undershoot is fixed on a loop route using cartographic realignment. The route has a start measure of 0 and an end measure of 4 before cartographic realignment.

After cartographic realignment, the undershoot on the loop is fixed and two intermediate calibration points are added at measures 1.33 and 2.67.

Cartographic realignment on a lollipop

In the following example, an undershoot is fixed on a lollipop route using cartographic realignment. The route has a start measure of 0 and an end measure of 5 before cartographic realignment.

After cartographic realignment, the undershoot on the lollipop is fixed and two intermediate calibration points are added at measures 2.46 and 3.86.

In the following example, an overshoot is fixed on a lollipop route using cartographic realignment. The route has a start measure of 0 and an end measure of 5 before cartographic realignment.

After cartographic realignment, overshoot on the lollipop is fixed.
