Resource Abstract:
- description: This data set contains Official Protraction Diagram (OPD) outlines in ESRI shapefile format. Atlantic Region
OPDs are approximately 2 degrees wide by one degree high. OPDs are further subdivided into blocks that are 4800 x 4800 meters
on a UTM plane (but this file does not include those blocks - only the OPD outline). Where the OPD hits the UTM zone boundary,
that zone boundary will be a geodesic line - which will appear slightly curved on the UTM plane. OPDs are numbered using the
United Nations International Map of the World Numbering System, and are generally named for land or hydrographic features
contained within the limits of the diagram. This file also includes the dividing line between the Atlantic Region and the
Gulf of Mexico Region in the area of the Florida Keys. Further information on the historic development of OPD's can be
found in OCS Report MMS 99-0006: Boundary Development on the Outer Continental Shelf: https://www.boem.gov/BOEM-Newsroom/Library/Publications/1999/99-0006-pdf.aspx
Because GIS projection and topology functions can change or generalize coordinates, these GIS files are considered to be approximate
and are NOT an OFFICIAL record for the exact OPD coordinates or areas. The Official Protraction Diagrams (OPDs) and Supplemental
Official Block Diagrams (SOBDs), available on the web in pdf format, serve as the legal definition for BOEM offshore boundary
coordinates and area descriptions.; abstract: This data set contains Official Protraction Diagram (OPD) outlines in ESRI shapefile
