Configure event replacement

Available with Location Referencing license.

When performing roadway maintenance tasks such as widening a section of highway, the events on a route may need to be retired or retired and replaced.

During roadway changes, events on an edited section of a route can be left as is, retired, or retired and replaced according to an event replacement configuration.

Event layers must be categorized on the Configure Replace Events dialog box before event replacement. The measures for the route do not change during event replacement.

Event replacement scenario

The configuration of event replacement requires categorizing the events in the feature service into three categories: As Is, Retire, and Retire and Replace.

Before event replacement

The following diagram illustrates a roadway section before replacement:

Roadway before replacement

Before replacement, the roadway section has eight events, three point events (events 1-3), and five linear events (events 4-8).
