Apply cartographic realignment

Mit der Location Referencing-Lizenz verfügbar.

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.

Hinweis:

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

1. Fügen Sie die Centerline- und die Network-Feature-Class einer Karte hinzu.

   Sie können ebenfalls eine Karte öffnen, in der die Centerline- und Network-Feature-Class bereits vorhanden ist.

   Hinweis:

   Vom Informationsmodell wird nur je eine Mittelachse an einer Position erwartet. Stellen Sie sicher, dass die bei der Bearbeitung verwendeten Mittelachsen keine anderen Mittelachsen im LRS überlappen.

   Hinweis:

   Herkömmlich versionierte Netzwerke müssen über eine Direktverbindung mit der Geodatabase bearbeitet werden. Nach Verzweigung versionierte Netzwerke, darunter alle Netzwerke, die mit einer benutzergenerierten Routen-ID konfiguriert wurden, müssen über einen Feature-Service bearbeitet werden.

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

3. Uncheck the network layer in the Contents pane, on the List By Selection tab , in the Selection list.
4. Check the centerline layer in the Contents pane, on the List By Selection tab , in the Selection list.
5. Select the centerline feature for the edit in the map.
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, on the List By Selection tab , in the Selection list.

   The cartographically realigned route appears.

   

   Hinweis:

   • 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 are acquired on all routes associated with the centerline being edited.

   Hinweis:

   Wenn eine Meldung zum Anfordern von Sperren oder Abgleichen angezeigt wird, ist die Option Konfliktvermeidung aktiviert.

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 that 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 that 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 that has a start measure of 0 and an end measure of 5 before cartographic realignment:

After cartographic realignment, overshoot on the lollipop is fixed.
