Abstract

Using GIS to build the history of a pipeline
Track: Pipeline and Gas Utilities

PHMSA saw benefits in using GIS to track the history of acquisitions and attribute changes for regulated pipelines. Previously, changes to pipelines were tracked only by operator name, not geospatially by pipe segment. Custom GIS tools were built to detect changes between an operator's required submissions of GIS data from one year to the next, building a history for changes to a pipeline segment. This will allow PHMSA to better isolate pipe-centric issues from operator-centric issues.
