Summary
Abstract: This GIS layer shows the Hubline, an approximately 29.5 mile natural gas pipeline constructed primarily in the ocean along the coast of Massachusetts between Beverly and Weymouth. The route travels in a southerly direction through the communities of Salem, Beverly, Marblehead, Swampscott, Lynn, Nahant, Winthrop, Boston, Hull, Quincy, and Weymouth. This dataset represents an as-built location of the pipeline. Original survey for the bottom position of the pipeline was established by a combination of surface position of the installation vessel using DGPS, diver's surveys, multibeam surveys, and sidescan surveys. The project was surveyed in accordance with the USACOE's minimum standards and techniques as defined in the engineering manual EM 1110-2-1003.

Purpose: The data were developed to support the requirements of both the Federal Energy Regulatory Commission and the U.S. Coast Guard, that a post construction survey be completed. Component of Massachusetts Office of Coastal Zone Management Human Uses database.

SUPPLEMENTAL INFORMATION: None.

Quality ATTRIBUTE ACCURACY REPORT: These is no assignment of attributes to these data.

LOGICAL CONSISTENCY REPORT: A georeferenced line CAD file was submitted as source data. Subsequent testing of the data was not performed.

COMPLETENESS REPORT: The line feature was converted into the ESRI shapefile format from a georeferenced engineering CAD file. This line file was used to derive the completeness of the pipeline route.

HORIZONTAL POSITIONAL ACCURACY REPORT: An accuracy report was not conducted on the data although the location of the converted and projected shapefile file was checked for consistency by overlaying it on the original electronic CAD file.

VERTICAL POSITIONAL ACCURACY REPORT: n/a
