Modify LRS Event (Location Referencing)

サマリー

Modifies properties of a linear referencing system (LRS) event.

使用法

• Modified fields should have the properties outlined in the ArcGIS Pipeline Referencing events data model and in the ArcGIS Roads and Highways events data model.

• This tool can be used to add or remove the following properties from an event:

  Present Event for a Continuous Network

  Event type	Supports route name	Supports spanning routes
  Line	No	N/A
  Line	Yes	N/A
  Point	No	N/A
  Point	Yes	N/A

  Modified Event for a Continuous Network

  Event type	Supports route name	Supports spanning routes
  Line	Yes	N/A
  Line	No	N/A
  Point	Yes	N/A
  Point	No	N/A

  Present Event for an Engineering Network

  Event type	Supports route name	Supports spanning routes
  Line	No	No
  Line	Yes	No
  Line	Yes	No
  Line	Yes	Yes
  Point	No	N/A
  Point	Yes	N/A

  Modified Event for an Engineering Network

  Event type	Supports route name	Supports spanning routes
  Line	Yes	No
  Line	No	No
  Line	Yes	Yes
  Line	Yes	No
  Point	Yes	N/A
  Point	No	N/A

ModifyLRSEvent example 1 (Python window)

The following script demonstrates how to use the ModifyLRSEvent tool in a Python window for the events to span routes.

# Name: Modify_LRS_Event_ex1.py
# Description: Modify an event registered to a network so that it spans routes.
# Requires: ArcGIS Location Referencing

# Check out license
arcpy.CheckOutExtension("LocationReferencing")

# Tool variables
in_feature_class = "c:/data.gdb/LRS/Event1"
event_id_field = "EventID"
route_id_field = "FromRouteId"
from_date_field = "FromDate"
to_date_field = "ToDate"
loc_error_field = "LocationError"
measure_field = "FromMeasure"
to_measure_field = "ToMeasure"
event_spans_routes = "SPANS_ROUTES"
to_route_id_field = "ToRouteId"
store_route_name = "STORE_ROUTE_NAME"
route_name_field = "FromRouteName"
to_route_name_field = "ToRouteName"

# Set current workspace
arcpy.env.workspace = "c:/data.gdb"
 
# Execute the tool
arcpy.ModifyLRSEvent_locref(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,

ModifyLRSEvent example 2 (stand-alone script)

The following script demonstrates how to use the ModifyLRSEvent tool in a stand-alone Python script so that the events span routes.

# Name: Modify_LRS_Event_ex2.py
# Description: Modify an event registered to a network so that it spans routes.
# Requires: ArcGIS Location Referencing

# Import arcpy module
import arcpy

# Check out license
arcpy.CheckOutExtension("LocationReferencing")

# Local variables:
in_feature_class = r"C:/data.gdb/LRS/Event1"
event_id_field = "EventID"
route_id_field = "FromRouteId"
from_date_field = "FromDate"
to_date_field = "ToDate"
loc_error_field = "LocationError"
measure_field = "FromMeasure"
to_measure_field = "ToMeasure"
event_spans_routes = "SPANS_ROUTES"
to_route_id_field = "ToRouteId"
store_route_name = "STORE_ROUTE_NAME"
route_name_field = "FromRouteName"
to_route_name_field = "ToRouteName"
 
# Process:  Modify LRS Event From Existing Dataset
arcpy.ModifyLRSEvent_locref(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)
