Pacific NAD 83 Official Protraction Diagram (OPD) Images

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.
