Description:
Abstract:
This data set contains Supplemental Official OCS Block Diagram (SOBD) images in Adobe pdf format for areas within the BOEM Alaska Region. Each SOBD describes a single block within an Official Protraction Diagram (OPD)
and shows the lines (Submerged Lands Act, Limit of "8(g) Zone", maritime boundaries and/or marine sanctuaries) which occur within that block and divide it into different areas. The SOBD contains additional coordinates and area calculations for an individual block. These data are scanned images of the official paper SOBDs produced by the BOEM. Note that not all OPDs have boundaries cutting through them, so not all OPDs will have SOBDs generated for them.  All current leasing activities will be done using  the most current SOBDs. Historical (outdated) SOBDs can be obtained by  contacting the Mapping and Boundary Branch.  Further information on the historic development of  OPDs can be found in OCS Report MMS 99-0006: Boundary Development on the Outer Continental Shelf:
http://www.boem.gov/BOEM-Newsroom/Library/Publications/1999/99-0006-pdf.aspx. Also see the metadata for each of the individual GIS files used to create these SOBDs. The Official Protraction Diagrams (OPDs) and Supplemental Official Block Diagrams (SOBDs), serve as the legal definition for BOEM offshore boundary coordinates and area descriptions.
Purpose:
These SOBDs 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.
Supplemental_Information:
The BOEM is making its existing cadastre data available at http://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.

Process_Description:
In house programs were used to protract offshore blocks OPD by OPD,
on a UTM grid for the offshore areas, and to intersect them with various
offshore boundaries.  The resulting points were then stored in the TIMS
database.  Other in-house program were used to create these diagrams
from the data stored in the TIMS database.
