Location errors allow you to determine data quality issues with LRS events. When events are created or edited using ArcGIS Pro feature creation or feature editing tools, or created by adding a row in an event layer attribute table, the status of the event record is indicated in the Location Error column in the attribute table row for the event record.
When an event is defined accurately using the attribute table or any other method, the result is a No Error value for the location error field. Any of the statuses other than the No Error value indicate a problem that must be resolved. The list of possible statuses is limited by the event creation or event editing technique in use.
For statuses that occur while using specific techniques, refer to event creation using feature creation, event editing using feature edits, event creation using the attribute table, and event editing using the attribute table.
Note:
The complete list of statuses also includes location errors that can occur when referent offset values are in use or after running the Translate Event Measures tool.
The following table provides the complete list of statuses.
| Location error | Description |
|---|---|
| Different From Route And To Route Line IDs | The from route and the to route have different line IDs. This is applicable to events associated with line networks. |
| From Referent Location Not Found | The event's from referent location was not found. |
| From And To Referent Locations Not Found | The event's from and to referent locations were not found. |
From Route Line Order Not Lower Than To Route Line Order | The from route does not have a lower line order than the to route. This is applicable to events associated with line networks. |
| Invalid Dates | The event's to date is before the event's from date. |
Invalid Length Field Value | The event's length field value is invalid. Applicable to referent offset events using the length field. For example, if the route is 1000 feet long, but the referent offset is set to 1500 using length as the referent method, the result is an invalid length. For example, if the route is 1000 feet long, but the referent offset is set to 1500 using length as the referent method, the result is an invalid length. |
| Invalid Route Line ID | The route does not have a valid line ID. This is applicable to events associated with line networks. |
| Invalid Route Line Order | The route does not have a valid line order. This is applicable to events associated with line networks. |
Invalid Location Route ID | The route location's route ID is invalid (NULL, empty, or invalid value). |
| Invalid Location Measure | At least one of the route location's measure values is invalid. |
| Invalid Referent Method | The event's referent is not valid. |
| Invalid Location Route ID | The route location's route ID is invalid (NULL, empty, or invalid value). |
Measure Extent Out Of Route Measure Range | The route location's shape was not found because the from measure and the to measure are outside of the route measures. |
Multi Match | Multiple matches were found. This error can occur after running the Translate Event Measures tool. |
| Multiple Route Locations Found | More than one point location was found. Measures may not be unique along the routes. This error can occur after running the Translate Event Measures tool. |
No Match | No matches were found in the target network for an event associated with a route in the source network. This error can occur after running the Translate Event Measures tool. |
Parent Event Not Found | The parent event could not be found. This is applicable to referent offset events. |
Parent Event Measure Location Not Found | The parent event's measure value is invalid. Applicable to referent offset events. |
| Partial Match For The From Measure And To Measure | The entire route location's shape was not found. Multiple matches were found for the from measure. This error can occur after running the Translate Event Measures tool. |
| Partial Match For The From Measure | The entire route location's shape was not found. The from measure is outside the route measure range. |
| Partial Match For The To Measure | The entire route location's shape was not found. The to measure is outside the route measure range. This error can occur after running the Translate Event Measures tool. |
Partial Multi Match For The From Measure | The entire route location's shape was not found. Multiple matches were found for the from measure. This error can occur after running the Translate Event Measures tool. |
Partial Multi Match For The From And To Measure | This error can occur after running the Translate Event Measures tool. |
Partial Multi Match For The To Measure | The entire route location's shape was not found. Multiple matches were found for the to measure. This error can occur after running the Translate Event Measures tool. |
| Route Measures Null | The route does not have m-values or the m-values are null. |
Route Location Not Found | The route location's shape was not found (the route has nom-values or the route location's measures don't exist on the route). |
| Route Not Found | The route does not exist (this could be due to the route not existing in the network or the route and event having different time ranges that do not overlap). |
| Route Shape Empty | The route does not have a shape or the shape is empty. |
| Route Not M Aware | The route is not an m-aware polyline. |
| To Referent Location Not Found | The event's to referent location was not found. |
XY Location Invalid | The event's XY location was not found on the route. |
Zero Length Extent | The from measure is equal to the to measure. |
