Summary
Description
This data set contains Official Protraction Diagram (OPD) outlines in ESRI Arc/Info export and Arc/View shape file formats for the BOEM Pacific Region. The use of OPD s makes it easier to refer to individual blocks within a region or planning area. Further information on the historic development of OPD s can be found in OCS Report BOEM 99-0006: Boundary Development on the Outer Continental Shelf. Because GIS projection and topology functions can change or generalize coordinates, these GIS files are NOT an OFFICIAL record for the exact OPD boundaries. Only the paper OPD or a digital image of them serve as OFFICIAL records.
