Update Measures From LRS (Location Referencing)

Доступно с лицензией Location Referencing.

Сводка

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.

Примечание:

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

Использование

• 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:

  

  Input Layer	Feature Type	Route ID	From Measure	To Measure	Comments
  Non-LRS input layer	Line	Route1	11	18	The line feature's geometry has a geometric match with the LRS network.

  

  Input Layer	Feature Type	Route ID	From Measure	To Measure	Comments
  Non-LRS input layer	Point	Route1	21		The point feature is coincident with the route on the LRS Network.

  

  Input Layer	Feature Type	Route ID	From Measure	To Measure	Comments
  Non-LRS input layer	Line				The line feature's geometry is not coincident with the input network. No information is returned.

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 Location 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.
