Reassign routes

Доступно с лицензией Location Referencing.

Reassignment is the technique by which all or a portion of a route or line is moved, or reassigned, to the immediate upstream or downstream of another route or line.

One example of a route reassignment is to split your routes or lines and merge (assign) them to another route or line after a pipeline has changed operation or ownership. Another example is to redesignate a portion of a pipe that falls on the other side of a boundary after an administrative boundary change.

In addition to route reassignment, the Reassign Route tool can update attribute fields and calibration points and apply user-configured event behaviors located along the reassigned route.

Scenarios that can be accomplished using the reassign activity are described below.

Примечание:

For all of the following scenarios, you can choose entire routes or partial routes:

Merging 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 start and end measure values for RouteXYZ.

Merging 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 is 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.

Splitting an existing route

RouteXYZ 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 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.

Renaming a route

You can rename an existing route and change its start and end 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.

Transferring 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.

Transferring calibration points to a 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 in the reassigned portion to the target route.

Примечание:

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

Downstream recalibration

The following examples describe recalibrating downstream. You can reassign routes with the source route calibrated or not calibrated downstream:

Reassignment with the source route not calibrated downstream

In this case, RouteX is split into two routes: Route1, which begins 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 check box is unchecked for the source route, the downstream route's (RouteX) measures remain intact.

Since the Recalibrate route downstream check box is unchecked for the target route, the measure of RouteY downstream of the reassigned portion is 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 can either transfer the existing values of the source route or type new values into the Reassign Route pane. The existing values of the source route are 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 also supports domains and subtypes.

Примечание:

The field alias appears in the Reassign Route pane rather than the field name.

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

Примечание:

Gap calibration rules are followed when editing routes.

  1. Add the network feature class to a map.

    You can also open a map in which the network feature class is already present.

    Примечание:

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

  2. Zoom in to the location where you want to reassign the route.
  3. Click the Reassign button Назначить заново 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 reassignment will take place.
    Примечание:

    To edit using feature services, the LRS Network must be published with the linear referencing and version management capabilities.

  5. Click the Effective Date drop-down arrow and choose a date for the edit.
    Подсказка:
    • Optionally, type the date in the Effective Date text box.
    • Double-click the empty Effective Date text box to populate it with today's date.
  6. In the Source Route section, click the Choose route from map button Выбрать маршрут на карте and click the route on the map to populate From Route Name.
  7. Provide a from measure value for the route using one of the following options:

    Type a measure.

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

    Choose the from measure value on the map.

    Click the Choose measure from map button Выбрать измерение на карте and click a measure on the map.

    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 starts from this location.

  8. Click the Choose route from map button Выбрать маршрут на карте and click the route on the map to populate To Route Name.
  9. Provide a to measure value using one of the following options:

    Type a measure.

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

    Choose the to measure value on the map.

    Click the Choose measure from map button Выбрать измерение на карте and click a measure on the map.

    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 takes 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 are retired.

  10. Choose whether 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. Provide a from measure value for the target route reassignment location using one of the following options:

    Type a from measure value.

    Type a value in the From Measure text box.

    Get a suggested value if you do not know the from measure value.

    Click the Recalculate From Measure button Пересчитать от измерения. The from measure value is calculated as the source measure length minus the to measure value.

    Примечание:

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

    Примечание:

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

  13. Provide the to measure value of the target route reassignment location using one of the following options:

    Type a measure.

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

    Choose the to measure value on the map.

    Click the Choose measure from map button Выбрать измерение на карте and click a measure on the map.

    Get a suggested value if you don't know the to measure value.

    Click the Recalculate To Measure button Пересчитать к измерению. The to measure value is calculated as the source measure length minus the from measure value.

    Примечание:

    • If you are filling a gap, this value is equal to the measure at the end of the gap.
    • If you are creating a route or adding the reassigned value to the end of the target route, this value is 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 is 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 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.

    Примечание:

    All of the calibration points between and including the from measure and to measure values, even those spanning routes in between, are included in the transfer of calibration points to the target route.

    The Reassign Route pane is fully populated.

  16. Click Run.
    Примечание:

    If your route edit will result in the introduction of one or more physical gaps on the route, a prompt appears to alert you before the tool is run. If you didn't plan to create a gapped route, answer No and edit your digitized centerlines so that no gaps result during route editing.

    If the route being edited already had one or more physical gaps, and no additional physical gaps were introduced by the edit, no prompt will appear.

    You can prevent unplanned centerlines by enabling snapping in the active map, or by enabling snapping using the Edit tab, Snapping group, Snapping button По замыканию.

    You can disable this warning by unchecking Warn before allowing route edits that can create physical gaps in Location Referencing options.

    The route is reassigned.

    Примечание:

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