This data set contains Official Protraction Diagrams (OPDs) in Adobe PDF
format. Pacific 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. 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. 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:
Also see the metadata for each of the individual GIS files used to create
these OPDs.
The Official Protraction Diagrams (OPDs) and Supplemental Official Block
Diagrams (SOBDs), serve as the legal definition for BOEM offshore boundary
coordinates and area descriptions.
These OPDs 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.
NOTE: OPDs offshore of Oregon and Washington that show the Submerged Lands Act and Section 8(g) Zone boundaries do not reflect post-2010 shoreline changes. The Submerged Lands Act and 8(g) Zone boundaries offshore of California were permanently immobilized by the U.S. Supreme Court on December 15, 2014.
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.
