Realign routes

Location Referencing ライセンスで利用可能です。

During the lifespan of a pipeline, the routes may change their geometry and length over time. Portions of the routes are removed while others are added. Major changes, such as environmental concerns, building a new pumping station, or repair work, may require a significant change in the shape of the route's geometry and length. ArcGIS Pipeline Referencing uses centerlines to perform such realignments. The centerline features used to realign routes can be existing features in the centerline feature class, be digitized into the centerline feature class (using aerial photography or other basemaps for guidance), be copied and pasted from other feature classes, or be imported from CAD files or other ArcGIS-supported data sources. The Realign Route tool can be used to realign a single route or to realign several adjoining routes that are part of the same line.

These tables explain the various parameters used in the Realign Route tool.

Parameters used for the Engineering Stationing networks

VariableEngineering Stationing network

Network

The network in which the Engineering Stationing routes exist.

Effective Date

Use this date for the date when the realignment has taken place on the ground.

Source Route: From Route Name

The route where the realignment starts.

Source Route: From measure

The measure on the source route where the realignment starts; shown by the green dot.

Source Route: To Route Name

The route where the realignment ends. In the case where the realignment takes place on a single route, the source route and target route are same.

Source Route: To measure

The measure on the target route where the realignment ends; shown by the red dot.

Realigned Route: From measure

The starting measure on the realigned portion.

Realigned Route: To measure

The ending measure on the realigned portion.

Realigned Route: Abandon the route(s)

Choose whether to abandon the source routes or to retire them.

Realigned Route: Recalibrate route downstream

Choose whether the tool will recalibrate the route downstream of the realignment measures.

Parameters used for the Continuous Measure networks

VariableContinuous Measure network

Network

The network in which the continuous routes exist.

Effective Date

The date when the realignment has taken place on the ground.

Source Route: Route Name

The route where the realignment takes place.

Source Route: From measure

The measure on the source route where the realignment starts; shown by the green dot.

Source Route: To measure

The measure on the source route where the realignment ends; shown by the red dot.

Realigned Route: From measure

The starting measure on the realigned portion.

Realigned Route: To measure

The ending measure on the realigned portion.

In the following examples, the route has a From measure of 0 and To measure of 10. The line order is 100.

Realign scenarios

  • In the first case, the source measure and target measure of the realigned portion of the route are the suggested measures by Pipeline Referencing. RouteX gets realigned and the measures downstream of the realignment are updated due to recalibration. The line order remains 100.
  • In the second case, there is no downstream recalibration after the realigned portion of the route. That results in an equation at the end measure of the realigned route. A new route gets created (RouteA) starting from the start of Source Route to the end of the realignment, the To measure location of the realigned route. RouteA gets the line order of 100 and RouteX’s line order changes to 200.
  • In the third case, if the From measure of the realigned route is changed in such a way that it results in an equation (if you don’t use Pipeline Referencing suggested measures) at the From and To measure locations and recalibrating downstream is not chosen, then that results in creation of two new routes. The first new route (RouteA) starts and ends at the start and end of the realign portion. The second new route (RouteB) starts from the end of the realign portion and goes till the end of the original route. RouteX’s line order remains 100, RouteA gets a line order of 200 and RouteB gets a line order of 300.

    Similarly, if the From measure and To measure of the realigned route are changed in such a way that it results in an equation (if you don’t use Pipeline Referencing suggested measures) at the From and To measure locations and recalibrating downstream is chosen, then that results in creation of two new routes. The first new route (RouteA) starts and ends at the start and end of the realign portion. The second new route (RouteB) starts from the end of the realign portion and goes till the end of the original route.

  • In the fourth case, if the From measure of the realigned route is changed in such a way that it results in an equation (if you don’t use Pipeline Referencing suggested measures) and recalibrating downstream is chosen, then that results in creation of a new route. The new route (RouteA) starts at the start of the realign portion goes till the end of the original route. RouteX’s line order remains 100 and RouteA gets a line order of 200.

Use the following steps for realigning routes:

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

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

    備考:

    The Pipeline Referencing information model expects only one centerline at any given location. Make sure the centerlines used for your edit are not overlapping with other centerlines in your LRS.

  2. Zoom in to the location where you want to realign the route.

    備考:

    The centerline feature for realigning the route must exist in the centerline feature class prior to realigning the route.

  3. Click the Realign button Realign on the Location Referencing tab.
    The Realign Route pane appears.
    Realign Route pane
  4. Click the Choose Centerlines button Choose Centerline on the Location Referencing tab, and click an existing centerline on the map at the location of the realignment.

    You can use multiple centerlines to realign a route.

    The selected centerlines are highlighted in blue, and the arrow shows the direction of digitization. The centerline provides the location and geometry of the realigned portion of the route.

    備考:
    • The order in which the centerlines are chosen determines the direction of increasing measure calibration. The direction of digitization of the centerline, depicted by the direction of the arrowhead on the selected centerline, also determines the direction of increasing measure calibration.
    • You can keep the centerlines chosen after realigning the route. This option is particularly useful if you are realigning a route in the Engineering Stationing network and want to realign another route for the Continuous network using the same centerlines, or vice versa. For more information about keeping centerlines chosen, see Set Location Referencing options.
  5. In the Realign Route pane, choose the network for which the realignment will take place.
    備考:

    Feature services published with linear referencing and branch version management will appear in the Network drop-down list. For more information, see Share as web layers with linear referencing and version management.

  6. Click the Effective Date drop-down arrow to choose an effective date for the realignment.
    • Alternatively, type the date in the Effective Date text box.
    • Double-clicking the empty Effective Date text box populates today's date.
  7. If the centerline touches the routes, the From Route Name, From Measure, To Route Name, and To Measure parameters in the Source Route section are autopopulated.

    If the centerline doesn't touch the route, you can use the pickers to populate the From Route Name, To Route Name, From Measure, and To Measure parameters. Additionally, you can type the measure values.

    備考:

    You can also check the Reassign to abandoned route(s) box to create routes to represent assets that are present but not in use. For more information, see Reassigning to an abandoned route.

  8. 備考:

    For the line network, the measures can be entered as station values in 00+00.00 or 00+00.000 format.

  9. The From Measure value in the Realigned Route section is automatically populated.

    The suggested source measure value is the measure at the location where the start of the centerline touches the source route.

    • Alternatively, you can type a source measure value of your choice.
    • If you do not know the source measure, allow Pipeline Referencing to suggest it. Click the Recalculate From Measure button Recalculate From Measure to do so. This value is calculated as the difference between the target measure value and the geometric length of the centerline.
  10. The target measure value is automatically populated in the Realigned Route section.

    The suggested target measure value is the measure at the location where the end of the centerline touches the target route. It is calculated by the geometric length of the centerline plus the target measure.

    • Alternatively, you can type a target measure value of your choice.
    • If you do not know the target measure, allow Pipeline Referencing to suggest it. Click the Recalculate To Measure button Recalculate To Measure to do so. This value is calculated as the sum of the source measure value and the geometric length of the centerline.
  11. Click Run.

    The tool transitions to the next page that shows the list of routes that are going to be retired due to the realignment.

  12. Choose one of the following options.

    If the realignment will result in the creation of a new route

    Click Next.

    The next screen allows you to give the new route a name and fill in any attributes you choose.

    lf a new route will not be created

    Click Run.

    The Realign Route pane transitions to the next page, which requires you to provide a name for the new route.

  13. Provide a name for the new route if one will be created.
  14. Click Next or Run. Depending on whether you chose to abandon or retire the source routes, the following will occur:
    • If you choose to retire, RouteX gets retired with its target date populated with the effective date.
    • Since the realignment was effective partially on RouteX, another version of RouteX gets created with its source date populated with the effective date and the target date as <NULL>. The source measure is 0 and target measure is 5. These were the measures that were unaffected by the realignment.
    • A new route (RouteA) is created in the realigned portion.
    • RouteY gets retired with its target date populated with the effective date.
    • RouteZ gets retired with its target date populated with the effective date.
    • Since the realignment was effective partially on RouteZ, another version of RouteZ gets created with its source date populated with the effective date and the target date as <NULL>. The source measure is 20 and target measure is 25. These were the measures that were unaffected by the realignment.

    The following table shows the measures for the routes after the realignment.

  15. Here are some cases where the direction of the centerline is against the direction of the routes in a line network:

    • Although a new route is created using the centerline, downstream calibration is not supported.
      example 1
    • No new route is created and the upstream of RouteZ is assimilated with the centerline.
      example 2

Reassigning to an abandoned route

The default option in Pipeline Referencing is to reassign any realigned routes to abandoned routes, rather than retire them. The workflow described previously is still applicable regarding the realignment. However, instead of retiring the existing routes as of the effective date of the edit, abandoned routes (new routes in the network) are created to represent assets that are still present, but not in use.

Leave the Reassign to abandoned route(s) check box checked to show the names of any abandoned routes that will be created as well as the line to which they belong.

You may also enter any required attributes for the abandoned route or routes at this time, or use the Apply values to all routes check box to type the same values for all abandoned routes.

See the diagram below to understand how the realigned route portions are reassigned to abandoned routes, shown with the _Ab suffix.
