Description:

Abstract:

This data set contains OCS block outlines (unclipped) to the GOM Planning Area Boundary in ArcGIS shape file format for the BOEM Gulf of Mexico Region. OCS blocks are used to define small geographic areas within an Official Protraction Diagram (OPD) for leasing and administrative purposes. These blocks have not been clipped along the Submerged Lands Act (SLA) boundary and along the Continental Shelf Boundaries. Additional details are available from: <http://www.boem.gov/uploadedFiles/BOEM/Oil_and_Gas_Energy_Program/Mapping_and_Data/99-0006.pdf> Because GIS projection and topology functions can change or generalize coordinates, and because shapefiles cannot represent true arcs, these GIS files are considered to be approximate and are NOT an OFFICIAL record for the exact block coordinates or areas. 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:

Block and Boundary data are generated to define areas on the OCS in support of the Federal offshore leasing program.

Supplemental_Information:

Prior to July 1, 2004, the Fish and Wildlife Research Institute (FWRI) was known as the Florida Marine Research Institute (FMRI). The institute name has not been changed in historical data sets or references to work completed by the Florida Marine Research Institute. The institute name has been changed in references to ongoing research, new research, and contact information.These data were obtained for use in the FMSAS. These data are maintained by the Bureau of Ocean Energy Management. All requests for these data should be made directly to BOEM.
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.
