Enable Derived Measure Fields (Location Referencing)

サマリー

Enables fields to store the derived route ID, derived route name, and derived measure fields for the specified LRS event feature class.

使用法

• The fields that will store the derived route ID, derived route name, and derived measure fields need to be available prior to running this tool.

• You can use an empty event feature class or event feature class that has loaded records.

コードのサンプル

EnableDerivedMeasureFields example 1 (Python window)

The following Python window script demonstrates how to use the EnableDerivedMeasureFields tool in immediate mode.

# Name: EnableDerivedMeasureFields_ex1.py
# Description: Enables fields to store the derived network route id, route name and measure fields.
# Requires: ArcGIS Location Referencing

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

# tool variables 
in_feature_class = "c:\\APR.gdb\\LRS\LineEventFeatureClass"
Derived_route_id_field = "DerivedRouteId"
Derived_route_name_field = "DerivedRouteName"
Derived_from_Measure_field = "DerivedFromMeasure"
Derived_to_Measure_field = "DerivedToMeasure"

# Set current workspace
arcpy.env.workspace = "c:\\EnableDerivedMeasureFields\\Py\\APR.gdb\\LRS\\LineEventFeatureClass"

# Execute the tool
arcpy.EnableDerivedMeasureFields_locref(in_feature_class, Derived_route_id_field, Derived_route_name_field, Derived_from_Measure_field, Derived_to_Measure_field)

# Check in license
arcpy.CheckInExtension('LocationReferencing')

EnableDerivedMeasureFields example 2 (stand-alone script)

The following script demonstrates how to use the EnableDerivedMeasureFields tool in a stand-alone Python script.

# Name: EnableDerivedMeasureFields_ex2.py
# Description: Enables fields to store the derived network route id, route name and measure fields.
# Requires: ArcGIS Location Referencing

# Import arcpy module
import arcpy

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

# Local variables:
in_feature_class = r"c:\EnableDerivedMeasureFields\Py\APR.gdb\LRS\LineEventFeatureClass"
Derived_route_id_field = "DerivedRouteId"
Derived_route_name_field = "DerivedRouteName"
Derived_from_Measure_field = "DerivedFromMeasure"
Derived_to_Measure_field = "DerivedToMeasure"

# Execute the tool
arcpy.EnableDerivedMeasureFields_locref(in_feature_class, Derived_route_id_field, Derived_route_name_field, Derived_from_Measure_field, Derived_to_Measure_field)

# Check in license
arcpy.CheckInExtension('LocationReferencing')
