Create LRS Event From Existing Dataset (Location Referencing)

Résumé

Registers an existing feature class as an LRS event.

Utilisation

• 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

Syntaxe

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})

Paramètre	Explication	Type de données
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 (Facultatif)	The to measure field in the event feature class. This parameter is required for line events.	Field
event_spans_routes (Facultatif)	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 (Facultatif)	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 (Facultatif)	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 (Facultatif)	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 (Facultatif)	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
