Atlantic NAD 83 Continental Shelf Boundary (CSB)

Description
This data set contains Continental Shelf Boundary (CSB) lines in ESRI shapefile format for the BOEMRE Atlantic Region. The CSB defines the seaward limit of federally managed OCS lands. This CSB file only includes the lateral boundaries between the United States and Canada, Bahamas or Cuba. That portion of the CSB defined by the 200 nautical mile line is not yet included. The BOEMRE CSB line is similar to, the Exclusive Economic Zone (EEZ) line published by NOAA, but the CSB may have slight differences. For example the CSB line will include intersection points with the BOEMRE OCS blocks. Additional details are available from OCS Report MMS 99-0006 - Boundary Development on the Outer Continental Shelf: http://www.boemre.gov/itd/pubs/1999/99-0006.PDF Because GIS projection and topology functions can change or generalize coordinates, these GIS files are considered to be approximate and are NOT an OFFICIAL record for the exact baseline coordinates. The Official Protraction Diagrams (OPDs) and Supplemental Official Block Diagrams (SOBDs) serve as the legal definition for BOEMRE offshore boundary coordinates and area descriptions.
