With the release of Esri's ArcGIS Pipeline Referencing (APR) in early 2017, Memphis Light, Gas & Water (MLGW) identified the extensions as desirable tools to manage their gas transmission assets. The key driver for MLGW was the ability to utilize software within the Esri stack for editing linear referenced pipelines, viewing and reporting. This presentation will focus on MLGW’s APR implementation and include elements around the hardware/software architecture, Utility Pipeline Data Model, data migration across multiple sources, implementation of the Esri software and creation of a viewing/reporting application within Web App Builder.

• Ability to program and configure against one location
• Streamlined integration points
Standardized Architecture
• Clarity for the User Community
• Regulatory Reporting, Asset Views, Mileage, Summaries
• No need to compare and/or combine data from multiple
locations for reporting
• MAKE OUR GIS A DECISION MAKING TOOL
Why UPDM?

15. Project Overview
Utility Pipeline Data Model
• Schema Extensions, RDMS/SDE &
Database Implementation
Data Migration
• Linearly Reference Transmission (GL-
ID)
• ArcGIS Gas Distribution Model

Desktop

17. Project Overview
oBenefits:
• Complete 10.5 Esri Architecture Up and Running
• Desktop, Server & ArcGIS Pro
• Allows Gas Distribution/GIS/IT to review, evaluate and plan for
next technology phase
• Transmission Data will remain in UPDM model and Dist Data
will ultimately be merged

18. ArcGIS Pipeline Referencing (APR)
Early Adopters

19. Early Adopters
First companies on board, including MLGW, find UPDM
appealing since both the distribution and transmission gas
assets can be stored within the same enterprise
geodatabase
•Operators seeing the benefit of Esri out of the box tools
versus third party software products for core pipeline
management
• ArcGIS Pipeline Referencing – Centerline & Event
Management
• Pro – Distribution

20. Early Adopters
With PODS Next Generation on the horizon and the
perceived jump from APDM to UPDM, we’ve found that
pure transmission operators are road-mapping and
planning prior to making the move
• Integration points to current PODS or APDM model
• Application compatibility (HCA/Class, Risk,
MAOP/MOP and Alignment Sheet Generation)
• Migration and Esri Version Upgrade Planning

21. ArcGIS Pipeline Referencing (APR)
Data

22. Data, Data, Data
How are pipeline routes being stored in the new model?
• Past models, stored pipelines and systems in
StationSeries and LineLoop/LineLoopHierarchy tables.
• UPDM…review existing systems hierarchy and make
key decisions for modeling the pipeline LRS networks
Do you still need historical stationing?
• Simply utilize continuous network and manage true
pipeline length/location?

23. Data, Data, Data
Data Mapping Phase
• Example: GasMain -> UPDM.P_Pipes
UPDM Database Extensions
• Where is data duplicated?
• Where can we consolidate?
• Between both source datasets or within the same
• What fields are truly needed to support GIS asset and integrity
management

24. Data, Data, Data
Data Migration
Establish Empty UPDM Schema
• Transmission vs Distribution
• Shared Features (P_Pipes, P_Fittings, P_Valves)
Configure APR
• LRS Networks, LRS Events, Event Response
• Centerline, Routes, Centerline Sequence

25. Data, Data, Data
Don’t discount the APR Toolbox!
• Streamlined Workflows
• GIS Centric
• Makes data loading a non-DBA task
• Append Events (Location Referencing Tools)
• Generate shapes and Event GUIDs
• Add, Retire or Replace

29. Licensing & Deployment
ArcGIS Pro Location Referencing Extension –
• Extension is part of the Pro Install!
• Named User versus Single Use?
• Single Use License: Provision APR as a single use on the same
machine

30. Licensing & Deployment
ArcGIS Pro Location Referencing Extension –
• Named User License: Use Pro License and the APR License
• Much easier to manage/implement
• Use Pro from any machine and utilize named user account for
authentication

31. Centerline & Data Loading
Migrate core features and LRS tables
• Follow Esri Documentation!
• The features/data that are migrated (outside the core) will assume
the LRS Network properties and users can proceed with using the
APR applications.

32. Centerline & Data Loading
Append Events – Location Referencing Toolbox
• Your new best friend!
• Event GUIDs
• Create shapes from source data in a tabular
format
• ROUTEID, M Value (From/To)
• Add, Retire or Replace
• Field Mapping – Visual Representation of
Mapped Columns
