Description:
Abstract:
This data set contains the Submerged Lands Act (SLA) boundary line (also
known as State Seaward Boundary (SSB), or Fed State Boundary)
in ESRI  shapefile formats for the BOEM Atlantic Region.  The SLA boundary
defines the seaward limit of a state's submerged lands and the landward
boundary of federally managed OCS lands.  In the BOEM Atlantic Region it
is projected 3 nautical miles offshore from the baseline.  Further
information on the SLA and development of this line from baseline points
can be found in OCS Report MMS 99-0006: Boundary Development on the Outer
Continental Shelf  http://www.boem.gov/uploadedFiles/BOEM/Oil_and_Gas_Energy_Program/Mapping_and_Data/99-0006.pdf.
Due to slight differences in process and purpose, NOAA's 3 nautical mile line depicted on its charts may differ in some areas from the SLA boundary depicted on BOEM maps and OPDs and should not be confused with the SLA boundary.  Therefore this boundary is the only boundary that should be used to depict state/federal seperation of jurisdiction for submerged lands.
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 Submerged Lands Act Boundary. The
Official Protraction Diagrams (OPDs) and Supplemental Official Block
Diagrams (SOBDs) serve as the legal definition for offshore boundary
coordinates and area descriptions.
Purpose:
The Submerged Lands Act boundary line and other cadastre
information the BOEM produces are generated in accordance with 30 Code of
Federal Regulations (CFR) 256.8 to support Federal land ownership and
mineral resource management.
Supplemental_Information:
The BOEM is making its existing cadastre data available at
http://www.boem.gov/Oil-and-Gas-Energy-Program/Mapping-and-Data/Index.aspx.  These data include Official
Protraction Diagrams (OPDs), and Supplemental Official OCS Block
Diagrams (SOBDs) in pdf format, and digital spatial data in ArcGIS
shapefile format.

Data_Quality_Information:
Logical_Consistency_Report:
The file is believed to be free of topologic errors.
Completeness_Report:
The entire SLA boundary line in the BOEM Atlantic Region is shown.
Positional_Accuracy:
Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report:
Coordinates for points forming the SLA boundary line are calculated
to 3 decimal places of a meter in the TIMS database.  However, GIS
functions which build topology, change projections, etc. may alter
coordinate values.  Furthermore, most of the SLA  boundary consists
of true arcs, but has been approximated by these shapefiles with
straight line segments.  For these reasons, these shapefiles are
considered to be approximate and are NOT an OFFICIAL record.
