- Abstract:
-
This data set contains OCS block outlines in ArcGIS shape file format for the BOEMRE Atlantic 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.boemre.gov/itd/pubs/1999/99-0006.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 BOEMRE offshore boundary coordinates and area descriptions.
- Purpose:
-
These block polygons and other cadastre information the BOEMRE 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 BOEMRE is making its existing cadastre data available at <http://www.boemre.gov/offshore/mapping/>. 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.

Coordinates values have been computed to .00000001 of a degree, but this shapefile is considered to be approximate. Where differences occur between the shapefile and the OPD and SOBD diagrams, the diagrams take precedence. This shapefile was created by extracting the X-Y UTM coordinates from the TIMS database. In order to create this Regional shapefile, which spans multiple UTM zones, all coordinates were re-projected to a single UTM zone (Zone 18). This file was then re-projected to geographic for distribution purposes. This resulted in some distortion (up to 0.009 meters) at the far East and West edges of the shapefile.

-
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 an 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.
