Calibration points can be retired when they are no longer relevant. The original calibration point should be retired by modifying its To Date value, and a new calibration point should be added with updated measure values and location information and a From Date set to the effective date of the change in the route calibration.
- Select a calibration point using the Edit button on the ArcGIS Desktop Editing toolbar.
- Change the To Date attribute to the effective date of the recalibration.
- Click the Apply Updates button on the Roads And Highways Editing toolbar.
The existing calibration point will be retired effective as of the calibration point's To Date value. The route is recalibrated by regenerating its shape based on the updated calibration point and its measures. If you set the time view of the LRS Network to an earlier date, you will see the route calibration as it was at that time. Event data will be updated according to each event layer's Calibrate Route rules.
