National Pipeline Mapping System


Location: U.S. Department of Transportation, Pipeline and Hazardous Materials Safety Administration (USDOT, PHMSA)

The U.S. Department of Transportation, Pipeline and Hazardous Materials Safety Administration (USDOT, PHMSA) is charged with ensuring the reliable and safe transport of hazardous liquid and gas commodities through a vast nationwide network of pipelines. PHMSA uses GIS as an asset management tool for this network and as a means to disseminate critical data. The foundation of this GIS is the National Pipeline Mapping System (NPMS) geospatial data repository, which Michael Baker has managed under contract with PHMSA since 1998. The NPMS is a seamless geospatial, linear referencing system database that contains data submitted by transmission pipeline, liquefied natural gas plant, and breakout tank operators. NPMS data is used by federal, state, and local government agencies in analysis of pipeline vulnerability to potential disasters and for planning, safety, and emergency response efforts. As the primary contractor for all GIS support to PHMSA, Michael Baker fulfills ad hoc mapping requests, performs spatial analysis, and processes the incoming NPMS data submissions. To help assure the quality of the data, Michael Baker maintains data standards to which pipeline submissions must adhere. When the pipeline-related submissions are received, Michael Baker performs a series of quality control checks to ensure compliance with the data standards. The NPMS website was developed and is maintained by Michael Baker. Additionally, Michael Baker developed and maintains five web map viewers, which are accessible from the NPMS website; each map viewer has a unique purpose in disseminating and updating pipeline data. The NPMS website also contains online data request and access request forms that Michael Baker developed; these forms both standardize and ease the request process. The NPMS system is a public facing system that must adhere to all federal and NIST security criteria. Formal security testing is done periodically by Michael Baker although the system is monitored continually for threats.
