Update Measures From LRS (Location Referencing)

Mit der Location Referencing-Lizenz verfügbar.

Zusammenfassung

Populates or updates the measures and route ID on Utility Network (UN) features such as pipes, devices, and junctions or on features in other non-UN or non-LRS feature classes.

This tool finds appropriate routes from the LRS Network parameter, gets the measures from that route, and populates or updates the measure and route attributes for the features in the non-LRS feature class.

Hinweis:

The ArcGIS Pipeline Referencing for Server extension is required to use this tool.

Verwendung

  • The input layer and LRS Network parameter layer must be from an LRS-enabled feature service.

  • The field properties of the Input Features and LRS Network parameters must match.

  • The spatial reference, x,y resolution, and x,y tolerance of the Input Features and LRS Network parameters must match.

  • A text log is written locally that states that the tool was executed and contains the following:

    • Information on any input features that failed validation
    • The route ID and measure values for the updated input features from before and after the update

  • The Input Features must be exactly coincident to the LRS Network features.

    The following diagrams and tables demonstrate how line and point features from the non-LRS Input Features that are coincident to Route1 in the LRS Network will be updated:

    The line feature's geometry has a geometric match with the LRS network.

    The point feature is coincident with the route on the LRS Network.

    Line

    The line feature's geometry is not coincident with the input network. No information is returned.

Syntax

UpdateMeasuresFromLRS(lrs_network, lrs_date, in_features, route_id_field, from_measure_field, {to_measure_field})
ParameterErklärungDatentyp
lrs_network

The feature service layer that contains the routes, route IDs, and measures.

Feature Layer
lrs_date

The date used to define the temporal view of the network for collecting the route and measure values.

Date
in_features

The layer that includes route ID and measure fields that will be updated based on feature geometry relative to routes in the LRS Network parameter.

Feature Layer
route_id_field

The field in the Input Features layer that contains the route ID value.

Field
from_measure_field

The field in the Input Features layer that contains the From measure value for polyline features.

Field
to_measure_field
(optional)

The field in the Input Features layer that contains the measure value for point features or the To measure value for polyline features.

Field

Abgeleitete Ausgabe

NameErklärungDatentyp
out_details_file

The output log file that lists the updated features in the Input Layer. This log file will include the before and after values for the route ID, From measure, and To measure fields for each updated feature.

Text File
out_features

The updated feature service layer.

Codebeispiel

UpdateMeasuresFromLRS example1 (Python window)

This code sample demonstrates how to use the UpdateMeasuresFromLRS function in the Python window.

# Name: UpdateMeasuresFromLRS_Sample1.py
# Description: This will populate the Route ID and measures in the input layer based on overlapping routes from the network layer. 
# The output is the input layer with the updated Route ID and measure values, and a .csv file with information on the updated features and errors.

# Requires: ArcGIS Pipeline Referencing
 
## Variables are supported from feature service only. Signing into Portal is required to access the feature service.
arcpy.SignInToPortal('https://yourdomain.com/portal', 'username', 'password')

# Initialize variables

# Map the lrs network from the feature service. Here, 8 corresponds to the lrs route network.
lrs_network_url =  r"https://yourdomain.com/server/rest/services/FeatureServiceName/FeatureServer/8"
lrs_network = arcpy.MakeFeatureLayer_management(lrs_network_url, "networkLayer")

# Map the input feature layer from the same feature service. Here, 18 corresponds to the input feature layer.
in_features_url = r"https://yourdomain.com/server/rest/services/FeatureServiceName/FeatureServer/18"
in_features = arcpy.MakeFeatureLayer_management(in_features_url, "inputFeaturesLayer")

lrs_date="10/8/2019"
route_id_field = "ROUTEID"
from_measure_field = "FROMMEASURE"
to_measure_field = "TOMEASURE"

# Execute the tool
arcpy.locref.UpdateMeasuresFromLRS(lrs_network, lrs_date, in_features, route_id_field, from_measure_field, to_measure_field)
UpdateMeasuresFromLRS example2 (stand-alone script)

This code sample demonstrates how to use the UpdateMeasuresFromLRS function as a stand-alone Python script in a feature service.

# Name: UpdateMeasuresFromLRS_Sample2.py
# Description: This will populate the Route ID and measures in the input layer based on overlapping routes from the network layer. 
# The output is the input layer with the updated Route ID and measure values, and a .csv file with information on the updated features and errors.
# Requires: ArcGIS Pipeline Referencing
 
# Import arcpy module

# Check out any necessary licenses
arcpy.CheckOutExtension("LocationReferencing")

## Variables are supported from feature service only. Signing into Portal is required to access the feature service.
arcpy.SignInToPortal('https://yourdomain.com/portal', 'username', 'password')

# Initialize variables

# Map the lrs network from the feature service. Here, 8 corresponds to the lrs route network.
lrs_network_url =  r"https://yourdomain.com/server/rest/services/FeatureServiceName/FeatureServer/8"
lrs_network = arcpy.MakeFeatureLayer_management(lrs_network_url, "networkLayer")

# Map the input feature layer from the same feature service. Here, 18 corresponds to the input feature layer.
in_features_url = r"https://yourdomain.com/server/rest/services/FeatureServiceName/FeatureServer/18"
in_features = arcpy.MakeFeatureLayer_management(in_features_url, "inputFeaturesLayer")

lrs_date="10/8/2019"
route_id_field = "ROUTEID"
from_measure_field = "FROMMEASURE"
to_measure_field = "TOMEASURE"

# Execute the tool
arcpy.locref.UpdateMeasuresFromLRS(lrs_network, lrs_date, in_features, route_id_field, from_measure_field, to_measure_field)
