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:

ParámetroExplicaciónTipo 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.

  • POINTThe geometry type of the event is Point. This is the default.
  • LINEThe 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_ROUTESThe event records span routes.
  • NO_SPANS_ROUTESThe 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_NAMEStores the route name with the event records.
  • NO_STORE_ROUTE_NAMEDoes 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
