Delete Routes (Location Referencing)

Disponible avec la licence Location Referencing.

Résumé

Deletes routes and associated data elements from the LRS Network.

Utilisation

• An LRS dataset is required to run this tool. To create an LRS dataset, add the calibration point, centerline, and redline layers to a feature dataset; then run the Modify LRS tool with the geodatabase as the input.

• As part of deleting routes, the Delete Routes tool also does the following:

  • Delete all Centerline Sequence records that have the routeId of deleted routes.
  • Delete all records in the lrs_edit_log table related to deleted routes.
  • Optionally delete associated centerlines, calibration points, and events.

    Attention :

    Running Delete Routes without using Delete associated centerlines, Delete associated calibration points, and Delete associated events may result in those centerlines, calibration points, and events not referencing to any route.

• The input must be a network feature class registered with an LRS Network.

• Select routes that need to be deleted before running the tool. Selection on an LRS Network feature class can be performed using the Select tool or definition queries.

• If no routes have been selected in the LRS Network feature class, the tool will fail.

• Selected route records with the same routeId will be deleted across time.

• If a route is selected in a Line Network, all routes in the same line are deleted across time.

• If the Delete associated calibration points check box is checked, calibration points associated with the routes will be deleted across time.

• If the Delete associated events check box is checked, all events registered with the network that have the same routeId of a deleted route will be deleted across time.

• If the Delete associated centerlines check box is checked, centerlines associated with the selected routes will be deleted. If centerlines are shared between networks, those common centerlines will not be deleted.

• It is recommended that you not run this tool on the default version of a database.

• If Delete Routes is run in an edit session, the deleted routes can be undone.

Attention :

If the Delete Routes tool is run outside an edit session, the deleted routes cannot be undone.

• In the case of routes that have a null routeId or lineId, the tool will run but records will not be deleted.

• The Delete Routes tool cannot be run on network layers in ArcGIS Pro when a time filter is turned on.

Syntaxe

DeleteRoutes(in_route_features, {delete_associated_calibration_points}, {delete_associated_events}, {delete_associated_centerlines})

Paramètre	Explication	Type de données
in_route_features	The route feature class registered with the network.	Feature Layer
delete_associated_calibration_points (Facultatif)	Specifies whether calibration points associated with the deleted routes will be deleted. DELETE_CALIBRATION_POINTS —Calibration points associated with the routes will be deleted. NO_DELETE_CALIBRATION_POINTS —Calibration points associated with the routes will not be deleted. This is the default.	Boolean
delete_associated_events (Facultatif)	Specifies whether events associated with the deleted routes will be deleted. DELETE_EVENTS —Events associated with the routes will be deleted. NO_DELETE_EVENTS —Events associated with the routes will not be deleted. This is the default.	Boolean
delete_associated_centerlines (Facultatif)	Specifies whether centerlines that are exclusively associated with the deleted routes will be deleted. DELETE_CENTERLINES —Centerlines exclusively associated with the selected routes will be deleted. If centerlines are shared between networks, those common centerlines will not be deleted. NO_DELETE_CENTERLINES —Centerlines will not be deleted. This is the default.	Boolean

Sortie dérivée

Nom	Explication	Type de données
updated_route_features	Updated LRS Network feature class.	Feature Layer

out_derived_route_features	The updated derived route feature layer.	Feature Layer

Exemple de code

DeleteRoutes example 1 (Python window)

The following Python window script demonstrates how to use the DeleteRoutes function in immediate mode.

# Name: DeleteRoutes_ex1.py
# Description: Delete routes and associated data elements from LRS Network.
# Requires: ArcGIS Location Referencing

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

# Tool variables
in_route_features= "PipelineNetwork"

# Set current workspace
arcpy.env.workspace = "C:\Data\UPDM.gdb"

# Execute the tool
arcpy.locref.DeleteRoutes('PipelineNetwork', 'DELETE_CALIBRATION_POINTS', 'DELETE_EVENTS', 'DELETE_CENTERLINES')

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

DeleteRoutes example 2 (stand-alone script)

The following stand-alone script demonstrates how to use the DeleteRoutes function.

# Name: DeleteRoutes_ex2.py
# Description: Delete routes and associated data elements from an LRS Network.
# Requires: ArcGIS Location Referencing

# Import arcpy module
import arcpy

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

# Provide the path of database
arcpy.env.workspace = r"C:\Users\Desktop\PipelineReferencing.gdb\LRS\LineNetwork"

# Convert network feature class to layer
arcpy.MakeFeatureLayer_management("LineNetwork", "networklyr")

# Process: Select Layer By Attribute
arcpy.SelectLayerByAttribute_management("networklyr", "NEW_SELECTION", "RouteID = '11316262800'")

# Run Delete Routes tool
arcpy.DeleteRoutes_locref("networklyr", "DELETE_CALIBRATION_POINTS", "DELETE_EVENTS", "DELETE_CENTERLINES")

print("Successfully deleted the selected route...")

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

DeleteRoutes example 3 (stand-alone script)

The following stand-alone script demonstrates how to use the DeleteRoutes function in a feature service.

# Name: DeleteRoutes_Pro_Ex3.py
# Description: Delete routes in stand-alone mode using a feature service. It is recommended to work in a version and post it into the default version.
# Requires: ArcGIS Location Referencing

# Import arcpy module
import arcpy

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

# Set tool variables
delete_associated_calibration_points = "DELETE_CALIBRATION_POINTS"
delete_associated_events = "DELETE_EVENTS"
delete_associated_centerlines = "DELETE_CENTERLINES"

# Input LRS route network is in a feature service. Sign into portal is required to access the feature service.
arcpy.SignInToPortal('https://yourdomain.com/portal', 'username', 'password')

## Make a layer of the LRS route network from the feature service for applying selection. Here, 1 corresponds to the LRS route network
in_route_layer = arcpy.MakeFeatureLayer_management("https://yourdomain.com/server/rest/services/FeatureServiceName/FeatureServer/1", 'route_layer')

## Process: Select Layer by attribute as required
arcpy.SelectLayerByAttribute_management(in_route_layer, "NEW_SELECTION", "RouteID = 'routeid1'")

# Process : Delete Routes
arcpy.DeleteRoutes_locref( in_route_layer, delete_associated_calibration_points, delete_associated_events, delete_associated_centerlines)

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