Utility GIS Mapping from Sentinel USA

Regulatory Compliance for Oil & Gas

Client Services & Regulatory Data Needs Assessments (RDNA)

Numerous sources and types of data form the foundation for High Consequence Area (HCA) analysis. Prior to performing the HCA identification process for our clients, the internal HCA-related data is assessed for completeness, currency, spatial accuracy, and attribute accuracy.

After successful completion of an RDNA, a data migration and conflation strategy is implemented, which includes the creation of a scalable GIS component.

Listed below are some of the key data services and elements included, along with any associated processing efforts.

Aerial imagery acquisition for the base layer for data migration.

Public domain GIS data set acquisition from Federal, State, County, and local government agencies to assist in identifying and classifying structures within the PIR buffer zones.

Geospatially re-align transmission pipeline coordinates with respect to internal GPS control and acquired aerial imagery.

Evaluate the attribute and spatial accuracy of the data to assign appropriate pedigree tolerance factors to account for inaccuracies and uncertainties in the data set.

Apply a standard data model (PODS) to the regulatory data set such that predefined relationships and domain values can be utilized.

HCA Determination Data Sources

Client Internal Data Assessment

Geospatial: Pipeline Centerline Coordinates

Attribute: MAOP and diameter

Public Source/External

Geospatial Data Analysis

Aerial Imagery Acquisition

Federal, State, and County-level GIS Data Sets

Attribute - public domain data sources such as Property Appraisers and Tax Assessors provide attribute data including but not limited to: address, business type (i.e. day commercial, industrial, hospitals churches, schools, day care centers, etc), building footprints

HCA Determination Process Flow
The HCA identification process is divided into six main steps, consisting of

Data Acquisition and Evaluation

Data Migration

Spatial Pedigree

Structure Identification and Attribute Pedigree

HCA Determination

Sentinel USA provides organizations with a variety of GIS related services, from building GIS platforms, optimizing existing GIS applications, or custom programming. In all cases, Sentinel adheres to an “any-to-any” philosophy. By not being tied to any particular format or platform, we have the flexibility to work with and/or deliver solutions to meet our clients requirements.

Whether operating as the mapping department of a One Call Center, Utility Company or providing HCA compliance services, Sentinel has developed unique expertise in building unified seamless land bases and point of interest data sets for large areas or a given clients area of interest,

Assisting O&G clients in compliance with PHMSA’s HCA (High Consequence Area) and DIMP regulations is perhaps the most complex of Sentinel’s offerings. In short, all pipeline operators must notify PHMSA where their pipelines pass under or close by sensitive areas (population or environmental) and have stringent integrity management practices for those areas. This is a challenge for most operators. By fine tuning the process, Sentinel protects utility infrastructure and saves its clients valuable time, resources and money.
