Service Description: Outer Continental Shelf Lease Blocks are used to assist in leasing on the Outer Continental Shelf. Blocks are numbered areas depicted on the OPDs or Leasing Maps. Most are of a uniform size according to the projection and type of map on which they are depicted, but many are of non-uniform size and shape due to their proximity to an adjacent map, projection zone, or boundary. Blocks should always be referred to with their parent protraction name or number since block numbers repeat from one protraction to the next.
Outer Continental Shelf (OCS) lease blocks serve as the legal definition for BOEM offshore boundary coordinates used to define small geographic areas within an Official Protraction Diagram (OPD) for leasing and administrative purposes. OCS blocks relate back to individual Official Protraction Diagrams and are not uniquely numbered. Only the most recently published paper or pdf versions of the OPDs or LMs or SOBDs should be used for official or legal purposes. The pdf maps can be found by going to the following link and selecting the appropriate region of interest within the OPD/SOBD table. http://www.boem.gov/Oil-and-Gas-Energy-Program/Mapping-and-Data/Index.aspx
