This data set contains Official Protraction Diagram (OPD) outlines
in ESRI shapefile format. Atlantic Region OPDs are approximately 2
degrees wide by one degree high. OPDs are further subdivided into blocks
that are 4800 x 4800 meters on a UTM plane (but this file does not include
those blocks - only the OPD outline). Where the OPD hits the UTM
zone boundary, that zone boundary will be a geodesic line - which will
appear slightly curved on the UTM plane. OPDs are numbered using the
United Nations International Map of the World Numbering System, and
are generally named for land or hydrographic features contained within
the limits of the diagram. These OPD outlines were clipped along the
Submerged Lands Act Boundary (3 mile line), Continental Shelf Boundary
(international boundaries), and the dividing line between the Gulf and
Atlantic Regions. Further information on the historic development of
OPD's can be found in OCS Report MMS 99-0006: Boundary Development on
the Outer Continental Shelf: https://www.boem.gov/BOEM-Newsroom/Library/Publications/1999/99-0006-pdf.aspx
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 OPD coordinates or areas. The Official
Protraction Diagrams (OPDs) and Supplemental Official Block Diagrams (SOBDs),
available on the web in pdf format, serve as the legal definition for BOEM
offshore boundary coordinates and area descriptions.
Cadastre information the BOEM produces are generated in accordance with 30 Code of Federal Regulations (CFR) Part 556.8 Subpart A, (formerly Part 256.8 Subpart A (2010)) to support Federal land ownership and mineral resource management.
The BOEM is making its existing cadastre data available at https://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.

BOEM Offshore Cadastral Data
The file is believed to be free of topologic errors.
Clipped outlines for all Atlantic OPDs are included.
Coordinates values have been computed to .00000001 of a degree, but this shapefile is considered to be approximate. Where differences occur between the shapefile and the OPD and SOBD diagrams, the diagrams take precidence.
This shapefile was created by extracting the X-Y UTM coordinates from the TIMS database. In order to create this Regional shapefile, which spans multiple UTM zones, all coordinates were re-projected to a single UTM zone (Zone 18). This file was then re-projected to geographic for distribution purposes. This resulted in some distortion (up to 0.009 meters) at the far East and West edges of the shapefile.

TIMS
Coordinates and attributes for OPD polygons.
In house programs were used to protract offshore blocks OPD by OPD,
on a UTM grid for the offshore areas. Additional boundaries, including
the Submerged Lands Act boundary, the Continental Shelf boundary, and
others were also computed and intersected with the OPD blocks. The
resulting points were then stored in the TIMS database. Other in-house
programs were used to create an ArcInfo Coverage from the data stored
in the TIMS database. That coverage was converted into a shapefile
(AT_SUBBLK.SHP) using ArcGIS. Portions of blocks outside federal
jurisdiction were removed, and the shapefile was further "dissolved"
to yeild just the clipped OPD outlines.
