Description:
Abstract:
This map layer shows official protraction diagram (OPD) and leasing map boundaries covering areas of the Outer Continental Shelf (OCS) within Federal jurisdiction. They are generated in accordance with 30 Code of Federal Regulations (CFR) 256.8 to support Federal land ownership and mineral resource management. Leasing Maps are irregularly shaped areas developed early in the offshore program for near-shore areas in the Gulf of Mexico. Elsewhere, OPD's were developed on a Universal Transverse Mercator (UTM) grid and are approximately one degree in latitude by two degrees in longitude, except in northern areas where they are three degrees in longitude. This map layer shows existing and planned OPD limits. Actual limits of Federal jurisdiction are defined by various international and maritime boundaries not presently depicted. Lease Map and OPD boundaries in the Gulf of Mexico were historically cut at the Submerged Lands Act (SLA) boundary, while in other areas the full OPD boundary is shown and therefore may include non-OCS lands within the rectangularly shaped OPD boundary. While the Gulf of Mexico Region uses the North American Datum of 1927, for this map layer those coordinates have been transformed to the North American Datum of 1983 to coincide with the OPD's in the other Minerals Management Service regions. This file updates the September 2000 map layer by including the OPD boundaries for Puerto Rico and the U.S. Virgin Islands.

Purpose:
These data are intended for geographic display and analysis at the national level, and for large regional areas. The data should be displayed and analyzed at scales appropriate for 1:2,000,000-scale data. Other sources must be used if exact coordinates are required for legal purposes. No responsibility is assumed by the Minerals Management Service or the National Atlas of the United States in the use of these data.

Coverages were created in Arc/INFO version 7.2.1 on a Sun Ultra Sparc Station 10 running Solaris 2.6


Data_Quality_Information:
Logical_Consistency_Report:
Coordinates for the original OPD and leasing map boundaries are calculated quantities and have been defined to be correct to 3 decimal places of a meter or foot. Coverages were topologically cleaned with the Arc/INFO command CLEAN using dangle length = 0 and fuzzy tolerance = 0.000002.
Completeness_Report:
All Federal OPD and Leasing Map boundaries in NAD83 coordinates are shown. The map layer covers the conterminous United States, Alaska, Hawaii, Puerto Rico, and the U.S. Virgin Islands.

Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report:
Individual OPD and Leasing Map corners are calculated values, shown to 3 decimal places of a meter (non-Gulf of Mexico) or foot (Gulf of Mexico). For precise coordinates, always use the files for an individual OPD or Leasing Map.

Process_Description:
The source data for the OPD and Leasing Map map layer is a theoretical mathematical derivation. In-house computer programs were used to generate the boundaries for each diagram. Leasing Maps and OPDs in the Gulf of Mexico were converted from NAD27 to NAD83, and the individual OPD's and Leasing Maps were then appended into one data set. For the purposes of this map, Atlantic Region OPD's south of 27 degrees North latitude were clipped to eliminate the appearance of overlap with Gulf of Mexico OPD's. The file was output in shapefile format for inclusion in the National Atlas of the United States.
