Reassign routes

Location Referencing ライセンスで利用可能です。

A reassignment is the way to assign a portion or entire route or line to the immediate upstream or downstream of another route or line. One example of a route reassignment is if you have to split your routes or lines and merge (assign) to another route or line as a result of the pipeline changing operation or under different ownership. In addition to reassigning the route, the Reassign Route tool can update attribute fields and calibration points, and apply end-user-configured event behaviors located along the reassigned route.

Here are some scenarios that can be accomplished by the reassign activity: The blue arrow shows the location of the reassignment portion.

備考:

For all these scenarios, you can choose the routes entirely or partially.

Merge multiple routes to a new route

RouteX, RouteY, and RouteZ are consecutive routes that belong to the same line. You can use the Reassign Route tool to merge all of them together into a new route, RouteXYZ, that belongs to the same line. RouteXYZ gets the line order of the first route that was used for merging, that is RouteX. RouteX, RouteY, and RouteZ get retired as a result of this operation. You can choose new From and To values for RouteXYZ.

Merge routes to an existing route

RouteX, RouteY, and RouteZ are consecutive routes that belong to the same line. You can use the Reassign Route tool to merge all of them together to route RouteZ that belongs to the same line. RouteX, RouteY, and RouteZ get retired as a result of this operation. The new RouteZ gets the line order of the first route that was used for merging, that is RouteX. In this case, the reassign portion will be from the start of RouteX to the end of RouteY. You are allowed to merge the reassigned portion to any immediate upstream or downstream route.

Split an existing route

Route XYZ has measures from 0 to 30. As shown in this example, you can split the route into two: Route1, which is a new route, and a new version of RouteXYZ. The existing RouteXYZ retires as a result of this operation. Route1 gets the line order of the RouteXYZ, and the new version of RouteXYZ gets the next line order value. For example, if the line order of RouteXYZ was 100 before the reassignment, after the reassignment, Route1 gets the line order of 100 and the new RouteXYZ gets the line order of 200.

Rename a route

You can rename an existing route and change its From and To measure values with the help of the Reassign Route tool. RouteXYZ is renamed to Route123 and with new measures. The line order remains the same. The existing RouteXYZ retires as a result of this operation.

Transfer a route to another line

Routes can be transferred entirely or partially to a new line. In this case, the reassign portion should be either on the upstream or downstream ends of the target line or in the immediate upstream or downstream of a gap between routes in the target line. As shown in the example, the red routes belong to Line1 and the green route belongs to Line2. You can take RouteY from Line1 and reassign it as a new route Route2 on Line2. RouteY gets retired and Route 2 gets a line order next to that of Route1 as a result of this operation.

Transfer calibration points to target route

Routes may have calibration points between the start and end of the route to maintain known measures between points. In that case, when reassigning the route, there is an option to transfer the calibration points contained within the reassigned portion to the target route. The black dots depict the location of calibration points transferred with the reassignment.

備考:

The option to transfer calibration points to target route is checked by default for reassign and is the preferred method to maintain established measures.

Recalibrate downstream

The following examples explain the concept of recalibrating downstream.

Reassign with the source route not calibrated downstream

In this case, RouteX is split into two routes: Route1, which starts at the start of the old RouteX and ends at the middle of the old RouteX. The To measure value of the newly created Route1 has been changed to 3 instead of the suggested measure of 5. Since the Recalibrate route downstream option is not chosen for the source route, the downstream route's (RouteX) measures remain intact.

The To measure value of the newly created Route1 has been changed to 3 instead of the suggested measure of 5. If the Recalibrate route downstream option is chosen for the source route, then downstream route RouteX’s measures would change to the from measure value of 0 and To measure value of 5.

Reassign with the target route calibrated downstream

In this case, a part of RouteX is merged with the adjoining route RouteY. The reassignment takes place from the middle of RouteX on the downstream side. Since the Recalibrate route downstream option is chosen for the target route, the measures of RouteY downstream of the reassigned portion gets recalibrated. The new version of RouteY now has a To measure value of 9.

Attributes

If your network has attribute fields other than the system-defined fields, you will have the opportunity to either transfer the existing values of the source route or to enter in new values into the Reassign Route pane. The existing values of the source route will be populated by default. If the reassignment spans multiple routes, the values from the first From value of the route will be populated by default.

This attribute section supports domains and subtypes as well.

備考:

The field alias will be displayed here (if an alias is assigned), rather than the actual field name.

The following steps can be used to implement any reassign scenario.

  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 reassign the route.
  3. Click the Reassign button Reassign on the Location Referencing tab.

    The Reassign Route pane appears.

  4. Click the Network drop-down arrow and choose the network in which the route extension 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.

  5. Click the Effective Date drop-down arrow to choose a date for the edit.
    ヒント:
    • Alternatively, type the date in the Effective Date text box.
    • Double clicking the empty Effective Date text box will populate today's date.
  6. In the Source Route section, click the Choose route from map button Choose route from map and click the route on the map to populate From Route Name.
  7. Enter a From measure value using one of the following methods.

    To type a measure

    Type a From measure value in the From Measure text box.

    To choose the From measure value in the map

    Click the Choose measure from map button Choose measure from map and click a measure in the map.

    To use the route start as the From measure value

    Check the Use route start measure check box.

    A green dot is placed at the location. The reassignment will start from this location.

  8. Click the Choose route from map button Choose route from map and click the route on the map to populate To Route Name.
  9. Enter a To measure value using one of the following methods.

    To type a measure

    Type a To measure value in the To Measure text box.

    To choose the To measure value in the map

    Click the Choose measure from map button Choose measure from map and click a measure in the map.

    To use the route end as the To measure value

    Check the Use route end measure check box.

    A red dot is placed at the location. The reassignment will take place on the routes or the portions of routes that exist between the green and red dots. The routes that are intersected by the reassignment portion will get retired.

  10. Choose whether you want to recalibrate the remainder of the reassigned route downstream of the reassigned portion.
    • Check the Recalibrate route downstream check box to recalibrate the remainder of the reassigned route downstream of the reassigned portion.
    • Uncheck the Recalibrate route downstream check box if you do not want to recalibrate the remainder of the reassigned route downstream of the reassigned portion.
  11. In the Target Route section, click the Choose route from map button to choose the target route.

    You can also type a new route name to reassign to a new route.

  12. Enter a From measure value of the target route reassignment location using one of the following methods.

    To type a From measure value

    Type a value in the From Measure text box.

    To get a suggested value if you do not know the From measure value

    Click the Recalculate From Measure button Recalculate From Measure. The From measure value is calculated as the source geometry length minus (-) the To measure value.

    備考:

    • If you are filling a gap, this value will be equal to the measure at the beginning of the gap.
    • If you are adding the reassigned route to the end of the target route, this value will be equal to the end measure of the target route.
    • If you are creating a new route or adding the reassigned portion to the beginning of the target route, this value will be 0.

    備考:

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

  13. Enter a To measure value of the target route reassignment location.

    To type a measure

    Type a To measure value in the To Measure text box.

    To choose the To measure value in the map

    Click the Choose measure from map button Choose measure from map and click a measure in the map.

    To get a suggested value if you don't know the To measure value

    Click the Recalculate To Measure button Recalculate To Measure. The To measure value is calculated as the source geometry length plus (+) the To measure value.

    備考:

    • If you are filling a gap, this value will be equal to the measure at the end of the gap.
    • If you are creating a new route or adding the reassigned value to the end of the target route, this value will be equal to the new end measure of the route.
    • If you are adding the reassigned route to the beginning of the target route, this value will be equal to the total length in the linear referencing method (LRM) measure units of the reassigned portion.

  14. Choose whether you want to recalibrate the remainder of the reassigned route downstream of the reassigned portion.
    • Check the Recalibrate route downstream check box to recalibrate the remainder of the reassigned route downstream of the reassigned portion.
    • Uncheck the Recalibrate route downstream check box if you do not want to recalibrate the remainder of the reassigned route downstream of the reassigned portion.
  15. Choose whether you want to transfer the source calibration points to the target route.

    The Transfer calibration points to the target route check box is checked by default and is the preferred method to maintain established measures between points.

    備考:

    All of the calibration points between and including the From measure and To measure values, even those spanning routes in between, will be included in the transfer of calibration points to the target route.

    The Reassign Route pane is fully populated.

  16. Click Next.

    The route is reassigned.
