While ArcGIS Roads and Highways is designed to be an authoritative linear referencing system within an organization, event data from other systems may not be able to be moved into the geodatabase and managed by ArcGIS Roads and Highways. To keep this external data in sync with the LRS as it changes over time, ArcGIS Roads and Highways provides a repeatable pattern to follow so that external systems stay in alignment with the LRS.
External events
The first step in the process to connect an external system with ArcGIS Roads and Highways is to establish a read-only connection to the external system using the Configure External Event With LRS tool. This allows ArcGIS Roads and Highways to see the route and measure information for the external event data. As the routes are edited in the LRS over time and event behaviors are applied to events within the geodatabase, ArcGIS Roads and Highways keeps a record of these edits to support pushing the updates out to the external system when it's ready to sync with ArcGIS Roads and Highways.
Relocate Event operation
The Relocate Event operation is used to initiate the sync process to determine the updates in the LRS that should be shared with the external event system. You can call the Relocate Event operation as frequently as you want to sync the external event configured with the LRS. When the operation is called, the route edits that have occurred within the LRS since the last time the tool ran are gathered by ArcGIS Roads and Highways. Comparing these route edits with the route and measure information from the external event, the operation determines which of these events would need to be updated to stay in alignment with the LRS. The Relocate Event operation then provides this updated information to the external event system so it can make the updates to the records.
Note:
The Relocate Event operation does not update the data in the external system. It provides a comprehensive list of event record updates that would need to be made by the external system to keep the event records aligned with the LRS.
