- Abstract:
-
These GIS data show the location of the location of an electric supply cable from Hyannis, Cape Cod to Nantucket Harbor on Nantucket Island in Nantucket Sound, Massachusetts. It is the western portion (National Grid Nantucket Electric Cable No. 2) of what are two 46kV cable lines routed from Cape Cod to Nantucket, Massachusetts installed by National Grid. The line feature was created using hardcopy geographic coordinates provided by National Grid in the form of the drawing "Nantucket Cable Project Submarine Cable Hyannis to Nantucket Marine Route Plan" dated February 2005. A marine survey was performed by Ocean Surveys Inc. on June 26 to July 4th and August 10 to August 12, 1994 to represent conditions.
- Purpose:
-
This dataset was created for reference and display of proposed energy facilities in Massachusetts coastal waters, and originally developed by National Grid to provide a record of as-built conditions. Component of Massachusetts Office of Coastal Zone Management Human Uses database.

- Logical_Consistency_Report:
-
Point data were plotted as X,Y coordinates based on tabulated hardcopy values. Subsequent testing of the data was not performed.
- Completeness_Report:
-
All displayed features were mapped based upon a set of hardcopy MA State Plane Island - Fipszone 2002 NAD 83 easting and northing coordinates supplied by National Grid. Coordinates of start, end, and angles were tabulated on drawing no. H-77900-0. The tabulated coordinates on the hardcopy drawing were used to derive the completeness of the cable route.
