Modify calibration points

Available with Location Referencing license.

ArcGIS Pipeline Referencing uses a simple feature class to store route calibration points for calibrating routes.

You can edit and modify route calibration points using the Edit Point tool in the Calibration Points group, on the Location Referencing tab or the Move tool in the Tools group of the Edit tab.

The Edit Point tool can also apply downstream recalibration to a route where a calibration point is modified. Pipeline Referencing automatically calibrates the route it references and applies the calibration event behavior. This tool also allows you to edit calibration points on a route and update their start date, retire date, and measure.

Measure value and temporality modification scenarios

You can update the start date, retire date, and measure of a calibration point using the Edit Point tool , in the Calibration Points group, on the Location Referencing tab. This tool also allows downstream recalibration to be applied to a route when a calibration point is edited.

With downstream recalibration

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

The following image shows the route calibration points and route calibration before modifying with the Recalibration route downstream check box checked.

The following image shows an existing calibration point edited with a user-defined measure of 5.

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

Without downstream recalibration

The following scenario describes editing a route calibration point without downstream calibration:

The following image shows the route's existing calibration points and route calibration:

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

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

Complex route calibration scenarios

Complex route calibration scenarios for complex routes including loop, branch, lollipop, and alpha routes are described below.

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 (2.5) than the existing measure (2), but no downstream measures are affected since Recalibrate route downstream is unchecked:

A calibration point is added using the new measure (2.5).

Calibration on a branch route

In the following example, a calibration point is added on a branch route (RouteX) using a different measure (2) than the existing measure (4.5), but no downstream measures are affected since Recalibrate route downstream is unchecked:

A calibration point is added using the updated measure (2). All downstream measures remain the same.

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 (2), but no downstream measures are affected since Recalibrate route downstream is unchecked:

The calibration point is updated using the new measure (2). All downstream measures remain the same.

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), but no downstream measures are affected since Recalibrate route downstream is unchecked:

The calibration point is updated using the new measure (3). All downstream measures remain the same.

Edit the measure and temporality of a calibration point

Complete the following steps to edit the measure and temporality of a calibration point on a route using the Edit Point tool, in the Calibration Points group, on the Location Referencing tab .

1. Add the LRS feature classes, including the calibration point feature class, to a map.

   Alternatively, open a map in which the LRS feature classes are present.

2. Click the Location Referencing tab.
3. Click the Edit Point tool on the Location Referencing tab in the Calibration Points group.

   Note:

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

   Note:

   You can edit the measure of a calibration point using an attribute editing tool, in which case the route's measures are recalibrated between the nearest upstream and downstream calibration points of the edited calibration point.

4. Select an existing calibration point on the map.

   The Edit Calibration Point pane appears with attributes for the selected calibration point populated.

   

5. Change the From Date and To Date values when this calibration is applied to the route.
6. Change the Measure value of this calibration point.
7. Choose whether you want to recalibrate the route downstream by checking or unchecking the Recalibrate route downstream check box.

   When this check box is checked, recalibration is applied to downstream calibration points along the route.

   For example, if an existing calibration (or measure) at the location where you want to add a calibration point is 5, and the next downstream calibration point at the end of the route has a measure of 10, changing a measure of 5 to 6 with Recalibrate route downstream checked results in a downstream calibration point with a measure of 11.

   When this check box is unchecked, no recalibration is applied to the downstream calibration points along the route.

   For example, if an existing calibration (or measure) at the location is changed from 5 to 6, leaving the Recalibrate route downstream check box unchecked results in the downstream calibration point maintaining a measure of 10.

8. Click Run.

   Calibration on the route is updated.
