With the release of Pro 2.7, ArcGIS Pipeline Referencing includes many enhancements to its software and documentation.
Support for vertical route geometries has been added. Additional support has been added for 3D in LRS calculations for LRS data in geographic coordinate systems, and when the x,y spatial reference units are different from the z-units of measure.
At ArcGIS 10.8.1 with ArcGIS Pro 2.6, notable updates were made to the Pipeline Referencing information model.
LRS Feature Dataset Requirement
A feature dataset is a collection of related feature classes that share a common coordinate system. Feature datasets are used to facilitate creation of controller datasets (sometimes also referred to as extension datasets), such as topology, utility network or pipeline referencing. Feature classes that are to be included in an extension dataset are first organized into a feature dataset.
To support service-based editing of your data in Pipeline Referencing, certain feature classes in the LRS data model must reside in a feature dataset in your geodatabase. If the feature classes and tables are modeled in advance, the following feature classes must be contained in a feature dataset: Centerline, Calibration Points, Redline, Networks, Events, and Intersections.
When a feature dataset is created, you must define its spatial reference. This includes the coordinate system, either geographic or a specific projection, as well as coordinate units and tolerances for x-, y-, z-, and m-values. All feature classes in a feature dataset must share a common coordinate system, and the x,y coordinates of their features should fall within a common spatial extent. When you create a feature class in an existing feature dataset, the coordinate system is inherited from the feature dataset.
Since measures and their precision are critical to the accuracy of any linear referencing method (LRM), the spatial reference, tolerance, and resolution settings for all these feature classes must align. This ensures that geometry and measures for routes, events, and intersections are correct in a linear referencing system (LRS) and remain in alignment. If any of the centerline, calibration point, redline, network, event, or intersection feature classes are modeled before they are registered with the LRS, ensure that the tolerance and resolution settings match.
If you use the Create LRS geoprocessing tool to create your LRS and minimum schema items, these required feature classes are automatically placed in a feature dataset.
If the LRS was created using ArcMap or ArcGIS Pro 2.5 or earlier, you need to move these feature classes into a feature dataset and run the Modify LRS geoprocessing tool to edit the LRS in ArcGIS Pro 2.6 or later. Additional modifications to the schema and/or APR re-configuration may be needed as part of this upgrade process.
The Gas and Pipeline Enterprise Data Management ArcGIS solution follows the LRS information model requirements with required features in the UtilityNetwork feature dataset. The Gas and Pipeline Enterprise Data Management is a unified solution for both networked and linear referenced pipelines based on ArcGIS Pro 2.6, ArcGIS Enterprise 10.8.1, UPDM 2020, and Utility Network Release 4.
The PODS 7.0 is also compatible with the LRS information model requirements with required features in the Features feature dataset.
APR implementations on versions of ArcGIS Pro 2.5 or older allowed for features to be outside a single dataset. When upgrading to ArcGIS Pro 2.6, the GIS administrator will be prompted to run the geoprocessing tool to Modify LRS. The following Error 130159 will be seen if the data model is not modified per the dataset requirements discussed above.
At ArcGIS Pro 2.6, you can now configure LRS intersection feature classes as well as generate and update intersections. The example below shows intersection of an LRS route with railroad layer.
The required fields for LRS intersection class are listed in the following table.
The name of the intersection ID field.
The name of the intersection.
The unique ID of the route.
The unique ID of the intersecting feature.
Feature Class Name
The name of the intersection point feature class.
The date the network became active.
The date the network was retired.
The measure on the dominant route where the intersection is located.
Here is a sample attribute table for the intersection of an LRS route with railroad layer.
In this session you will learn the best practice approaches for moving your geodatabase with your LRS from traditional to branch versioning to support the new feature service-based network editing and conflict prevention capabilities in ArcGIS Pipeline Referencing/ArcGIS Roads and Highways
Learn how ArcGIS Pipeline Referencing can be used to manage and edit pipeline networks event data on a spatial linear referencing system (LRS). This session will provide a product overview with demonstrations to orchestrate linear referenced pipeline data management and data editing work such as data loading, pipe replacements, linear referenced event behaviors, the REST API to extend LRS capabilities across the Enterprise, and web-based event editing with the Event Editor.
Learn how ArcGIS Roads and Highways can be used to manage and edit roadway network centerline data, roadway characteristic and asset data on a spatial linear referencing system (LRS). This session will provide a product overview with demonstrations of supported roadway data editing workflows, linear referenced event behaviors, tools to detect measure errors in data, the REST API to extend LRS capabilities across the enterprise, web-based event editing with the Event Editor, and web-based roadway network reporting with the Roadway Reporter.
Learn how ArcGIS Pipeline Referencing can be integrated with a Utility Network to support linear referencing and network connectivity on a pipe system. This session will provide an overview of the configuration of Pipeline Referencing and a Utility Network together, the enhancements to LRS Network editing activities, and support for maintaining measures on Utility Network assets like devices and junctions.
In this session we will demonstrate the new features and capabilities in ArcGIS Roads and Highways in the ArcGIS Pro 2.5 and 2.6 releases, including Roads and Highways Desktop, Roads and Highways Server, and the Event Editor.
While the Pipeline Referencing Dev Summit demo theater couldn't be given in person in Palm Springs, the session was recorded and is available for anyone interested in the Location Referencing REST API and how your organization can utilize it.
ArcGIS Pipeline Referencing (APR), an extension for ArcGIS, provides advanced linear referencing capabilities to manage pipeline data. APR is being used by transmission pipeline operators, vertically integrated gas utilities and midstream gathering organizations. Esri offers a 2-day instructor led training to get you started on the application capabilities including real-world examples.
Hands-on training includes topics such as:
Getting started with ArcGIS Pipeline Referencing
ArcGIS Pipeline Referencing concepts
Learn to configure, administer and mange linear referencing networks and events
Learn common pipeline workflows such as rerouting, retirement, splitting and merging of centerlines and event editing/maintenance
Streamline organization specific workflows and best Practices
