At the US Department of Transportation’s Pipeline and Hazardous Materials Safety Administration (PHMSA) our mission is to protect people and the environment from the risks of hazardous materials transportation. To do this, we establish national policy, set and enforce standards, educate, and conduct research to prevent incidents. We also prepare the public and first responders to reduce consequences if an incident does occur.
The National Pipeline Mapping System (NPMS) includes a linear referenced (LRS) geospatial database containing hazardous liquid trunk lines and low-stress pipelines, as well as gas transmission pipelines. PHMSA builds and maintains the NPMS by collecting GIS data submissions and updates from over 1000 pipeline operators every year. These pipeline operators are responsible for meeting the NPMS submission standard; however, creating a single LRS database from over 1000 different data sources still poses a unique set of challenges and opportunities. Some of these opportunities include the ability to track the history of a pipeline through acquisitions and divestitures, and the spatial integration of other PHMSA databases and records. During this presentation we will review some of our standards for operator GIS submissions, customized tools and how PHMSA disseminates information from the NPMS to support our mission to protect people and the environment.
Leigha Gooding provided contractual support for NPMS data maintenance and analysis since 2006, until joining PHMSA in 2011 as their GIS Specialist. She held an integral role in designing and coordinating the NPMS’s transition into a linear referenced database, including the development of customized tools and mapping applications, and conducting outreach, GIS education and data interoperability. Leigha is a 2006 geography graduate from the University of Pittsburgh at Johnstown and currently resides in Washington, DC.
