Create LRS Event From Existing Dataset (Location Referencing)—ArcGIS Pro

Zusammenfassung

Registers an existing feature class as an LRS event.

Verwendung

The event feature class must reside in a feature dataset that contains an LRS dataset.
Learn more about the LRS dataset in the Pipeline Referencing data model or the LRS dataset in the Roads and Highways data model.
The event feature class fields must include the properties specified in the Pipeline Referencing events data model or in the Roads and Highways events data model.
The following event behavior rules are set by default:
Activity Rule
Calibrate Route

Stay Put
Retire Route
Stay Put
Extend Route
Stay Put
Reassign Route
Stay Put
Realign Route
Stay Put
Carto Realign Route
Honor Route Measure

Activity	Rule
Calibrate Route	Stay Put
Retire Route	Stay Put
Extend Route	Stay Put
Reassign Route	Stay Put
Realign Route	Stay Put
Carto Realign Route	Honor Route Measure

Syntax

arcpy.locref.CreateLRSEventFromExistingDataset(parent_network, in_feature_class, event_id_field, route_id_field, from_date_field, to_date_field, loc_error_field, measure_field, {to_measure_field}, {event_spans_routes}, {to_route_id_field}, {store_route_name}, {route_name_field}, {to_route_name_field})

Parameter	Erklärung	Datentyp
parent_network	The network to which the event will be registered.	Feature Layer
in_feature_class	The event to be registered.	Feature Layer
event_id_field	The event ID field in the event feature class.	Field
route_id_field	The route ID field if the feature class is a point event or the from route ID field if the feature class is a line event and event_spans_routes is set to SPANS_ROUTES.	Field
from_date_field	The from date field in the event feature class.	Field
to_date_field	The to date field in the event feature class.	Field
loc_error_field	The location error field in the event feature class.	Field
measure_field	The measure field if the feature class is a point event or the from measure field if the feature class is a line event.	Field
to_measure_field (optional)	The to measure field in the event feature class. This parameter is required for line events.	Field
event_spans_routes (optional)	Specifies whether the event records will span routes. NO_SPANS_ROUTES —The event records will not span routes. This is the default. SPANS_ROUTES — The event records will span routes.	Boolean
to_route_id_field (optional)	The to route ID field for events that span routes. This parameter is required if the in_feature class parameter geometry type is polyline and event_spans_routes is set to SPANS_ROUTES.	Field
store_route_name (optional)	Specifies whether the route name will be stored with the event records. NO_STORE_ROUTE_NAME — The route name will not be stored with the event records. This is the default. STORE_ROUTE_NAME —The route name will be stored with the event records.	Boolean
route_name_field (optional)	The route name field if the feature class is a point event that doesn't span routes or the from route name field if the feature class is a line event that spans routes. This parameter is required if store_route_name is set to STORE_ROUTE_NAME.	Field
to_route_name_field (optional)	The to route name field for line events that span routes. This parameter is required if store_route_name is set to STORE_ROUTE_NAME.	Field
