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.
Using the Reassign tool, you can implement a reassignment using the Transfer to another line method. Routes are transferred to a new line if a new line name is provided, or routes are transferred to an adjacent line if an existing line name is provided.
Parameters in the networks
The following tables describe the parameter values used in the Reassign tool:
For a network that supports lines
| Variable | Description |
|---|---|
Network | The network that supports lines in which the routes exist. |
Effective Date | This is the date when the reassignment has taken place on the ground. |
Source: From Route Name | The route where the reassignment starts. |
Source: From Measure | The measure on the source route where the reassignment starts; shown by the green dot. |
Source: To Route Name | The route where the reassignment ends. For example, if the reassignment takes place on a single route, the source route and target route are the same. The source routes should belong to the same line. |
Source: To Measure | The measure on the source route where the reassignment ends, shown by the red dot. |
Target: Route Name | The route to which the reassigned portion will be added. This can also be a new route. |
Target: From Measure | The starting measure on the reassigned portion. |
Target: To Measure | The ending measure on the reassigned portion. |
Transfer to another line
Complete the following steps to transfer to another line as part of the reassignment.
- Add the
network feature class to a map.
Alternatively, open a map in which the network feature class is present.
Note:
Traditionally versioned networks must be edited through a direct connection to the geodatabase. Branch versioned networks, which include networks configured with a user-generated route ID, must be edited through a feature service.
- Zoom in to the location where you want to reassign the route.
- On the Location Referencing tab, in the Routes group, click Reassign
.The Reassign Route pane appears.
- Click the Network drop-down arrow and choose the network in which the route reassignment will take place.
Note:
To edit using feature services, the LRS Network must be published with linear referencing and version management capabilities.
- Click the Effective Date drop-down arrow and choose a date for the edit.
Tip:
You can also provide the date, or double-click the empty Effective Date text box to insert the current date.
- In the Source section, click the Choose route from map button
and click the route on the map to populate From Route Name.Note:
After clicking the Choose route from map button
or the Choose measure from map button 
, you can
hover over the routes to see the route and measure at the location of the pointer.If only one applicable route exists at the edit location, click to select it. If multiple routes are applicable, click to choose one of the applicable routes using the Select Route dialog box.
You can set map scale options for display of route and measure information on the Options dialog box, on the Location Referencing tab.
- Provide a starting measure value for the route by doing one of the following:
- Provide a value in the From Measure text box.
- Click the Choose measure from map button and click a measure on the map.
- Check the Use route start measure check box.
A green dot is placed at the location. The reassignment starts from this location.
- Click the Choose route from map button and click the route on the map to populate To Route Name.
- Provide a To Measure value by doing one of the following:
- Provide a To Measure value in the To Measure text box.
- Click the Choose measure from map button and click a measure on the map.
- 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.
- 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.
- Choose whether to transfer the source calibration points to the target route using the Transfer calibration points to the target route check box.
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.
Note:
All of the calibration points between and including the starting measure and ending 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 populated.
- Choose Transfer to another line as the method for reassignment:
- In the Target section, click the Choose line from map button and select the target line on the map.
The source will be transferred to this line.
The name of the line you selected on the map populates the Line Name text box and the source routes will be transferred to this line.
Note:
Alternatively, provide a new name. If the provided name doesn't exist in the database, a new line is created, and the source routes will be transferred to this new line.
- Click Next.
The list of routes that are going to be retired as a result of this operation appears.
Note:
This pane only appears with Networks supporting lines.
- Click Next.
The Reassign Route pane appears.
The Route Name, From Measure, and To Measure values for each source route are populated. You can update them in the following steps.
- Optionally, provide another route name.
- Optionally, provide a From Measure value for the target route reassignment location by doing one of the following:
- Provide a value in the From Measure text box.
- Click the Recalculate From Measure button
. The starting measure value is calculated as the source measure length minus the ending measure value.
Note:
For the line network, the measures can be entered as station values in 00+00.00 or 00+00.000 format.
- Optionally, provide a To Measure value for the target route reassignment location by doing one of the following:
- Provide a To Measure value in the To Measure text box.
- Click the Recalculate To Measure button . The ending measure value is calculated as the source measure length minus the starting measure value.
If the network has attribute fields other than the system-defined fields, you can either transfer the existing values of the source route or provide new values in 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, subtypes, contingent values, and attribute rules.
Note:
The field alias, not the field name, appears in the Reassign Route pane.
- Click Run.
Note:
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 don't plan to create a gapped route, click No and edit the digitized centerlines so that no gaps result during route editing.
If the route being edited already had one or more physical gaps, and no more physical gaps were introduced by the edit, no prompt appears.
You can prevent unplanned centerlines by enabling snapping in the active map, or by enabling snapping using the Edit tab, Snapping group, Snapping button
.You can disable this warning by unchecking the Warn before allowing route edits that can create physical gaps check box on the Location Referencing tab on the Options dialog box.
Note:
If a message regarding acquiring locks or reconciling appears, conflict prevention is enabled.
The route is reassigned.
