How a Unified Data Model made NPMS Readiness Possible
In Brief
A Clear Path to a PHMSA-Compliant Pipeline Data System
Preparing a first-time National Pipeline Mapping System (NPMS) submission is challenging when pipeline information exists across CAD files, engineering drawings, and legacy GIS layers. To build a compliant, unified pipeline data model, an Alaskan-based oil and gas operator partnered with Resource Data. Together, the teams implemented Esri’s Gas and Pipeline Referencing Utility Network Foundation and the Utility and Pipeline Data Model (UPDM).
The result was the operator’s first accurate, centralized, and NPMS-ready geospatial pipeline dataset and a modern geospatial foundation to support ongoing regulatory reporting and operational use.
The Challenges
Scattered Data Blocked Reliable Reporting and Readiness
The Pipeline and Hazardous Materials Safety Administration (PHMSA) rely on accurate geospatial pipeline data to support emergency responses, operations, and regulatory compliance. However, our client’s data was scattered across multiple locations and file types. This includes CAD files, spreadsheets, ground survey data, engineering drawings, and various GIS layers, making it difficult to maintain a clear consistent view of the network or generate PHMSA-compliant reports.
Building their first Esri UPDM system was essential for accurately managing data and producing a compliant NPMS ready data model. Without a compliant data model, the operator risked NPMS submission failure, regulatory penalties, and delays to future pipeline development.
The Solution
Centralized UPDM Framework for Pipeline Network Visibility and Compliance
To meet NPMS requirements and establish a compliant geospatial data pipeline, Resource Data implemented Esri’s Gas and Pipeline Referencing Utility Network Foundation, which includes the UPDM. The UPDM provides the standardized geodatabase structure used to organize pipeline information in ArcGIS Pro and deploy it into the client’s environment.
The model was first structured to represent key pipeline assets such as pipes, valves, and fittings that use subtypes for clear organization. Resource Data then configured domain lists, including approved pipe materials and valve types, to ensure consistent attribute entry. Once the structure was in place, the team digitized assets to create accurate geospatial features and attributes for each asset and added the required NPMS metadata, including primary, technical, and public contacts.
After building the model, it was deployed into the client’s ArcGIS Enterprise environment. This created a unified, compliant pipeline data system ready for our clients’ first NPMS submission and ongoing operational use.
Features
Inside the Framework: The Architecture Behind Accuracy
-
Centralized Geospatial Data Eliminates Scattered Records
Pipeline data and attributes from CAD files, engineering drawings, spreadsheets, and legacy GIS layers were merged into a single authoritative data model, eliminating scattered and inconsistent records.
-
Configured Editing Workflows for Ongoing Data Maintenance
Esri’s built-in ArcGIS Pro tasks and validation tools were configured to guide staff through data entry, editing, and quality checks, ensuring consistent updates across engineering, GIS, and operations teams.
-
Standardized Attribute Details Supports Reliable Reporting
The UPDM geodatabase captures essential attributes such as pipe material, valve type, diameter, installation year, and component classifications, providing consistent, structured information that supports operational workflows and NPMS reporting.
-
Detailed Component Representation Improves Network Visibility
Each pipeline element, including pipes, valves, fittings, and other components, was modeled as precise geospatial features with complete attribute details. This gives the operator a clear digital representation of the entire pipeline system.
“Resource Data has supported the NPMS submission processes for more than 5 north slope oil and gas operators and several in the lower 48.”

Results
A Fully Compliant, Enterprise-Ready Pipeline Data Model
With the UPDM and Utility Network in place, the operator is successfully prepared to submit its pipeline data to the National Pipeline Mapping System (NPMS) for the first time. The centralized model replaced scattered files with a clear, compliant pipeline model that meets PHMSA’s reporting requirements.
