PHMSA migrates 510,917-mile NPMS database to PODS
PHMSA has completed the migration of the 510,917-mile National Pipeline Mapping System (NPMS) Database to PODS. This large dataset is visible to the general public via the Public View application on www.npms.phmsa.dot.gov.
By utilizing the PODS Data Model, PHMSA is now able to track attributes in a pipe-centric, rather than operator-centric, manner. This enables PHMSA to research changes to a pipe segment through the years, differentiate operator performance from pipeline performance, detect changes between an operator's current submission and previous NPMS submissions, and to query the database for either the current derived layer, or for historic data.
