Summary
Abstract: This data set contains Official Protraction Diagram (OPD) outlines in ESRI Arc/Info export and Arc/View shape file formats for the MMS Atlantic 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 MMS 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.

Purpose: Official Protraction Diagrams and other cadastre information the MMS 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 MMS is making its existing cadastre data available at http://www.mms.gov/ld/Maps.htm and on CD-ROM. These data will include digital images of MMS ... View entire text

Quality LOGICAL CONSISTENCY REPORT: Coordinates for OCS blocks and projected boundaries are calculated quantities and have been defined to be correct to 3 decimal places of a meter. The OPD polygon coverage was topologically cleaned with Arc/Info's 'CLEAN' command using a fuzzy tolerance of 0.000002 applied to the coverage in longitude/latitude coordinates.

COMPLETENESS REPORT: All NAD83 Federal Atlantic Ocean offshore protraction diagram (OPD) boundaries are shown.

HORIZONTAL POSITIONAL ACCURACY REPORT: Official protraction diagram (OPD) corners are calculated values to 3 decimal places of a meter. However, GIS functions which build topology, change projection, etc. may degrade coordinate values. For that reason, these GIS files are NOT an OFFICIAL record.
Access Constraints ACCESS CONSTRAINTS: None. The Block and Boundary data is in the public domain.
