Modify LRS Event (Location Referencing)

概要

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:

パラメーター説明データ タイプ
in_feature_class

The input feature class or feature layer for the event.

Feature Layer
event_id_field

Name of the event ID field.

Field
route_id_field

Name of the route ID field.

Field
from_date_field

Name of the from date field.

Field
to_date_field

Name of the to date field.

Field
loc_error_field

Name of the location error field.

Field
measure_field

Name of the measure field if it is a point event or from measure field if it is a line event.

Field
to_measure_field
(オプション)

Name of the to measure field. Required only for line events.

Field
event_spans_routes
(オプション)

Determines if the event records will span routes.

  • AS_ISNo change to the property. This is the default.
  • NO_SPANS_ROUTESThe event records do not span routes. Applicable only for line events.
  • SPANS_ROUTES The event records may span routes. Applicable only for line events.
String
to_route_id_field
(オプション)

Name of the to route ID field. Required only if it is a line event and it spans routes.

Field
store_route_name
(オプション)

Determines if the event records will store the route name.

  • AS_ISNo change to the property. This is the default.
  • STORE_ROUTE_NAMEStores the route name with the event records.
  • NO_STORE_ROUTE_NAMEDoes not store the route name with the event records.
String
route_name_field
(オプション)

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.

Field
to_route_name_field
(オプション)

Name of the to route name field. Required if it is a line event, and store_route_name and SPANS_ROUTES are set.

Field

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,
                            store_route_name, route_name_field, to_route_name_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)
