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 Merge to adjacent route method. Either a portion of a route, the entire route or multiple routes can be reassigned and merged with the adjacent route.
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. |
For continuous networks
| Variable | Description |
|---|---|
Network | The network in which the continuous routes exist. |
Effective Date | This is the date when the reassignment has taken place on the ground. |
Source: Route Name/ID | 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 Measure | The measure on the source route where the reassignment ends, shown by the red dot. |
Target: Route Name/ID | 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. |
Merge to an adjacent route
Complete the following steps to merge to an adjacent route 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 Route ID.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.
- Provide an ending measure value by doing one of the following:
- Provide an ending 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 the Merge to adjacent route method for reassignment:
Merge to an adjacent route. - In the Target section, click the Choose route from map button and choose the target route from the map.
Alternatively, provide the name of an existing route.
- Provide a starting measure value for the target route reassignment location by doing one of the following:
- Provide a starting measure 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:
- 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.
Note:
For the line network, the measures can be entered as station values in 00+00.00 or 00+00.000 format.
- Provide the ending measure value of the target route reassignment location by doing one of the following:
- Provide an ending 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.
Note:
- If you are filling a gap, this value is equal to the measure at the end of the gap.
- 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.
- 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.
- Choose whether to recalibrate the remainder of the target 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.
- Click Next.
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 starting 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.
The Reassign Route pane appears.
- Click Run.
Note:
If your route edit results in the introduction of one or more physical gaps on the route, an alert appears 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, and Snapping
.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.
The route is reassigned.
Note:
If a message regarding acquiring locks or reconciling appears, conflict prevention is enabled.
