This data set contains Official Protraction Diagram (OPD) outlines
in ESRI Arc/Info export and Arc/View shape file formats for the BOEM
Pacific Region. The use of OPD s makes it easier to refer to individual
blocks within a region or planning area. Further information on the SLA and development of this line from baseline points can be found in OCS Report BOEM 99-0006: Boundary Development on the Outer Continental Shelf. https://www.boem.gov/BOEM-Newsroom/Library/Publications/1999/99-0006-pdf.aspx These OPD diagrams
were clipped along the Submerged Lands Act (SLA) boundary and along
lines contained in the Continental Shelf Boundaries (CSB) GIS data files
to show only those blocks or portions thereof within federal
jurisdiction.
Because GIS projection and topology functions can change or
generalize coordinates, these GIS files are NOT an OFFICIAL record for
the exact OPD boundaries. Only the paper OPD or a digital image of
them serve as OFFICIAL records. PDF versions available for printing can be found here: https://www.boem.gov/Oil-and-Gas-Energy-Program/Mapping-and-Data/Pacific.aspx
Official Protraction Diagrams and other 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
will include digital images of BOEM data at the regional, planning area,
Official Protraction Diagram (OPD), and Supplemental Official OCS Block
Diagram (SOBD) levels and digital spatial data in ESRI shape format at the regional or planning area levels.

Coordinates for OCS blocks and projected
boundaries are calculated quantities and have been defined to be correct
to 3 decimal places of a meter. The OPD polygon coverage was
topologically cleaned with Arc/Info s CLEAN command using a fuzzy
tolerance of 0.000002 applied to the coverage in longitude/latitude
coordinates.
All NAD83 Federal Pacific Ocean offshore protraction
diagram (OPD) boundaries are shown.
Official protraction diagram
(OPD) corners are calculated values to 3 decimal places of a meter.
However, GIS functions which build topology, change projection, etc.
may degrade coordinate values. For that reason, these GIS files are
NOT an OFFICIAL record.

Coordinates of the protraction diagram corners were
taken from TIMS.
The source data for the OCS protraction diagram
coverage (OPD) is a theoretical mathematical derivation. In-house
computer programs are used to generate the boundaries for each
diagram. These OPD diagrams were clipped along the Submerged Lands
Act (SLA) boundary and along lines contained in the Continental Shelf
Boundaries (CSB) GIS data files to show only those blocks or portions
thereof within federal jurisdiction.
