Event behavior for cartographic realignment

Mit der Location Referencing-Lizenz verfügbar.

Cartographic realignment is the method of updating the route geometry based on aerial imagery, as-built drawings, or input from field data collectors in a manner that does not change measures. To do this, you can directly modify the centerline that is associated with the route.

Cartographic realignment scenario

When cartographic realignment occurs, events are impacted depending on the configured event behavior for the event layer. The following are the results of executing the Apply Event Behaviors geoprocessing tool on event features.

Before cartographic realignment

Honor Route Measure behavior

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. Since the route is not time sliced, the event is also not time sliced because of this operation.

After cartographic realignment

When performing a cartographic realignment, you may choose the Honor Route Measure rule.

BehaviorDescription

Honor Route Measure

Preserves the measure of the event.

Hinweis:

Point events follow the same behavior as linear events.

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.

Cartographic realignment on routes in a line network with events that span routes

The following sections detail how event behavior rules are enforced when a route on a line in a line network is cartographically realigned.

Honor Route Measure behavior

Cartographic realignment will result in the following:

  • Event1 will have its shape regenerated to match the updated shape of the routes on which it is located.
  • Event2 will have its shape regenerated to match the updated shape of the routes on which it is located.

Before Honor Route Measures

The following diagram and table provide details about the route and its measures before cartographic realignment.
