    • OCS Protractions - Alaska Region

    Metadata Updated: September 17, 2024

    This data set contains a Alaska OCS Region scale spatial footprint of the outer boundaries of the Bureau of Ocean Energy Management’s (BOEM’s) Official Protraction Diagrams (OPDs). These polygons are clipped to the Submerged Land Act Boundary and Continental Shelf Boundaries. It is updated as needed. OPDs are mapping products produced and used by the BOEM to delineate areas available for potential offshore mineral leases, determine the State/Federal offshore boundaries, and determine the limits of revenue sharing and other boundaries to be considered when leasing offshore waters. The OPDs serve as the legal definition for BOEM offshore boundary coordinates and area descriptions. This dataset shows only the outline of the maps that are available from BOEM. Only the most recently published paper or pdf versions of the OPDs should be used for official or legal purposes. Further information on the history of the development of OPDs can be found in OCS Report MMS 99-0006: Boundary Development on the Outer Continental Shelf.This data was created in the applicable NAD83 UTM Projection and re-projected to WGS84 Geographic. Because GIS projection and topology functions can change or generalize coordinates, these GIS files are NOT an OFFICIAL record for the exact boundaries. These files are to be used for Cartographic purposes only. This data should not be used to calculate area.
