Cartographic realignment is the method of updating the route geometry based on aerial imagery, as-built drawings, or input from field data collectors. To do this, you can directly modify the centerline that is associated with the route.

Nota:
Events are not updated until the Apply Event Behaviors tool is applied after route edits. If you are using conflict prevention, you are prompted to run Apply Event Behaviors before posting can be completed.
Cartographic realignment scenario
When cartographic realignment occurs, events are impacted, depending on the configured event behavior for each event layer. The following are the results of executing the Apply Event Behaviors tool on event features.
| Behavior | Description |
|---|---|
Honor Route Measure | Preserves the measure of the event and changes shape as per the route. |
Honor Referent Location | Changes both measure and geographic location to maintain the referent location of the event using a persistent offset value. |
Nota:
Point events follow the same behavior as line events.
Honor Route Measure behavior
Cartographic realignment results in the following:
- The Event1 shape is regenerated to match the updated shape of the routes on which it is located.
- If Update route measure during cartographic realignment parameter is enabled in the LRS Network using the Modify Network Calibration Rules, the measures are updated during cartographic realignment.
Before Honor Route Measure
The following diagram provides details about the route before cartographic realignment:
After Honor Route Measure
The geographic location and the measures of the event change to that of the resultant cartographically realigned route, and the route and the event always remain in sync.
The following diagram provides details about the route after cartographic realignment:
Honor Referent Location behavior
The geographic location and measures of the event can change to maintain the referent offset.
Before Honor Referent Location
The following diagram provides details about the route before cartographic realignment:
After Honor Referent Location
Nota:
If the referent is not valid or not present during event behavior processing, the events are used to regenerate the event shape.
The following diagram provides details about the route after cartographic realignment:
Detailed behavior results
The following section details how event behavior rules are enforced when a route is cartographically realigned:
Honor Route Measure behavior
The Honor Route Measure rule either preserves the measure of the event or changes the measure proportionally to the route's measure change as a result of cartographic realignment.
Before Honor Route Measure behavior

The following table provides details about the event before cartographic realignment:
| Event ID | Route ID | From Date | To Date | From Measure | To Measure |
|---|---|---|---|---|---|
Event1 | Route1 | 1/1/2000 | <Null> | 0 | 10 |
After Honor Route Measure behavior
If Update route measure during cartographic realignment parameter is disabled in the LRS Network using the Modify Network Calibration Rules, the measures are the same after cartographic realignment.

If Update route measure during cartographic realignment parameter is enabled in the LRS Network using the Modify Network Calibration Rules, the measures are updated after cartographic realignment.
The following diagram provides details about the route after cartographic realignment with update route measure enabled:
The following table provides details about the event after cartographic realignment with update route measure enabled:
| Event ID | Route ID | From Date | To Date | From Measure | To Measure |
|---|---|---|---|---|---|
Event1 | Route1 | 1/1/2000 | <Null> | 0 | 10 |
Honor Referent Location behavior
The Honor Referent Location rule changes both measure and geographic location to maintain the referent location of the event using a persistent offset value.
Events can have columns to derive the location of the event using stored information about a referent location. The following referent locations can be stored:
- Offset distance from any point feature in the geodatabase
- Offset distance from an intersection point feature
- Offset distance from a point event feature
- Offset distance from an x,y coordinate
- Offset distance from a station
The cartographic realignment has the following effects:
- Event1 has its shape regenerated to honor the from referent and to referent offset.
- A point event is used as the referent feature.
- If Update route measure during cartographic realignment parameter is enabled in the LRS Network using the Modify Network Calibration Rules, the measures are updated after cartographic realignment.

|---|---|---|---|---|---|
Event1 | Route1 | 1/1/2000 | <Null> | 21.5 | 26 |

The following sections detail how event behavior rules are enforced when a route in a line network is cartographically realigned:
Honor Route Measure behavior
Cartographic realignment results in the following:
