Description:
Abstract:
This data set contains OCS block outlines (clipped) 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 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.

Acknowledgement of the FWC-FWRI (Florida Fish and Wildlife Conservation Commission-Fish and Wildlife Research Institute) as the data source, and the originator BOEM, would be appreciated in any products developed from these data, and such acknowledgment as is standard for citation and legal practices for data source is expected by users of this data. Please cite the original metadata when using portions of the record to create a similar record of slightly altered data, such as reprojection. If any data are modified or adjusted, please share the edited information with FWC. Users should be aware that comparison with other data sets for the same area from other time periods may be inaccurate due to inconsistencies resulting from changes in mapping conventions, data collection, and computer processes over time.

Process_Step:
Process_Description:
In house programs were used to protract the blocks on a UTM grid for the offshore areas, and to intersect those blocks with various boundaries including the SLA and CSB boundaries. The resulting points were then stored in the TIMS database. Other in-house programs were used to create ArcInfo Coverage from the data stored in the TIMS database. That coverage was converted into a shapefile using ArcGIS, and any portions of blocks landward of the SLA boundary or seaward of the CSB boundary were removed. The shapefile was further "dissolved" to remove any other internal boundary lines, leaving only the block outlines.
