Modify calibration points

Mit der Location Referencing-Lizenz verfügbar.

Roads and Highways uses a simple feature class to store calibration points for calibrating routes. The Edit Point tool on the Location Referencing tab allows you to edit calibration points on a route and update their start date, retire date, and measure. Roads and Highways automatically calibrates the route it references and applies the calibration event behavior. This tool can also apply downstream recalibration to a route where a calibration point is modified.

Tipp:

If you need to update the location of a calibration point, delete the existing calibration point and add a new calibration point.

The following scenario is an example of route calibration with downstream recalibration after modifying a calibration point:

Step A—The route's existing calibration points and route calibration before modifying with the Recalibration route downstream check box checked are shown.

Step B—An existing calibration point is edited with a user-defined measure of 5.

Step C—When the tool is run, the calibration point is edited, downstream calibration points have calibration updated, and the route is recalibrated.

The following scenario is an example of route calibration point without downstream calibration after modifying a calibration point:

Step A—The route's existing calibration points and route calibration are shown.

Step B—An existing calibration point is edited with a user-defined measure of 5.

Step C—The result of route calibration with no changes to downstream calibration point values is shown.

Complex route calibration scenarios

The following sections provide examples of calibration on complex routes including loop, branch, lollipop, and alpha routes.

Calibration on a loop route

In the following example, a calibration point is added in the middle of a loop route (RouteX) using a different measure (3) than the existing measure (2). Since Recalibrate route downstream is checked, downstream measures are updated.

A calibration point is added using the new measure (3). All downstream measures on RouteX are updated.

Calibration on a branch route

In the following example, a calibration point is added on a branch route (RouteX) using a different measure (9) than the existing measure (4.5). Since Recalibrate route downstream is checked, downstream measures are updated.

A calibration point is added using the new measure (9). All downstream measures are updated.

Calibration on a lollipop route

In the following example, an existing calibration point (0) at the beginning of a lollipop route (RouteX) is updated using a new measure (5). Since Recalibrate route downstream is checked, downstream measures are updated.

The calibration point is updated using the new measure (5). All downstream measures are updated.

Calibration on an alpha route

In the following example, an existing calibration point (2.33) on an alpha route (RouteX) is updated using a new measure (3.33). Recalibrate route downstream is checked.

The calibration point is updated using the new measure (3.33). All downstream measures are updated.

Complete these steps to edit calibration points on a route:

1. Click the Location Referencing tab.
2. Click the Edit Point tool on the Location Referencing tab.

   Hinweis:

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

3. Select a calibration point to modify on the map.

   The Edit Calibration Point pane appears with the Network, Route ID, From Date, To Date, and Measure fields automatically populated with information from the selected calibration point on the map.

4. Optionally, change the From Date and To Date fields to specify when the calibration will be applied to the route.
5. Optionally, change the value in the Measure field.
6. Optionally, check the Recalibrate route downstream check box to recalibrate downstream calibration points along the route.
7. Click Run.

   The calibration point is updated on the map.

   Hinweis:

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

8. Optionally, repeat steps 1 through 7 to modify additional calibration points.
