Create LRS Event (Location Referencing)

Resumen

Creates line or point events for an existing LRS Network.

Uso

• The output of the tool is a feature class.

• Derived networks cannot be used as parent networks.

• The event feature class fields have properties outlined in the ArcGIS Pipeline Referencing events data model and in the ArcGIS Roads and Highways events data model.

• The following event behavior rules are set by default:

  Activity	Rules
  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

Sintaxis

CreateLRSEvent(parent_network, event_name, {geometry_type}, 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})

Parámetro	Explicación	Tipo de datos
parent_network	The network to which the event is registered.	Feature Layer
event_name	The event to be registered.	String
geometry_type (Opcional)	The geometry type of the output event. POINT —The geometry type of the event is Point. This is the default. LINE —The geometry type of the event is Polyline.	String
event_id_field	The event ID field available in the event feature class.	String
route_id_field	Name of the route ID field if it is a point event that does not span routes, or from route ID field if the event_spans_routes parameter is set to SPANS_ROUTES.	String
from_date_field	The from date field available in the event feature class.	String
to_date_field	The to date field available in the event feature class.	String
loc_error_field	The location error field available in the event feature class.	String
measure_field	Name of the measure field if it is a point event or from measure field if it is a line event.	String
to_measure_field (Opcional)	Name of the to measure field. Required only for Line events.	String
event_spans_routes (Opcional)	Specifies whether the event records spans routes. SPANS_ROUTES —The event records span routes. NO_SPANS_ROUTES —The event records do not span routes. This is the default.	Boolean
to_route_id_field (Opcional)	Name of the to route ID field. Required only if the geometry_type parameter is set to LINE and the event_span_routes parameter is set to SPANS_ROUTES.	String
store_route_name (Opcional)	Specifies whether the route name should be stored with the event records. STORE_ROUTE_NAME —Stores the route name with the event records. NO_STORE_ROUTE_NAME —Does not store the route name with the event records. This is the default.	Boolean
route_name_field (Opcional)	The route name field if it is a point event that does not span routes, or the from route name field if it is a line event that spans routes. Required if STORE_ROUTE_NAME is set.	String
to_route_name_field (Opcional)	The to route name field for line events that span routes. Required if STORE_ROUTE_NAME is set.	String

Salida derivada

Nombre	Explicación	Tipo de datos
out_feature_class	The updated event feature layer.	Feature Layer
