These shapefiles contain only the calculated turning points for these geodetic lines. These lines may need to be densified before projecting from geographic to other coordinate systems. The precise coordinates in this file are preliminary, pending final review. Purpose: These boundaries will provide the basis for more accurate delineation of OCS planning areas; assist in determining “affected state” status under the Coastal Zone Management Act and OCS Lands Act; and assist in the section 18 comparative analysis to determine “an equitable sharing of developmental benefits and environmental risks among regions.” For further information please see the Federal Register Notice from January 3, 2006. See: http://edocket.access.gpo.gov/2006/pdf/05-24659.pdf 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 include digital images of MMS diagrams at the regional, planning area, Official Protraction Diagram (OPD), and Supplemental Official OCS Block Diagram (SOBD) levels and digital spatial data in Arc/Info export or Arc/View shape format at the regional or planning area levels.

Completeness_Report: All Gulf of Mexico Federal OCS Administrative Boundaries are included. They have been clipped at the approximate SLA boundary and Continental Shelf Boundary (CSB) which marks the limit of U.S. jursdiction for offshore mineral development. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: Coordinates for points forming the Federal OCS Administrative Boundaries were calculated in CARIS to 0.001 meter resolution. Note however that these are geodetic lines and may need to be densified before projecting to other coordinate systems in order to preserve the proper shape between turning points.

Process_Step: Process_Description: The National Baseline points for the Gulf Coast of Florida were obtained from NOAA, and input to the MMS Technical Information Management System (TIMS) (an Oracle Database). TIMS only stores coordinates to 8 decimal places for a degree, so this process rounded the National baseline points from 9 to 8 decimal places. The National Baseline points were then processed with the fixed baseline points for Texas, Louisiana, Mississippi and Alabama. (Technically for Texas and Louisiana it is the SLA boundary that is fixed, but fixing the boundary also fixes the baseline by default.) The National Baseline is published on NOAA nautical charts. The maritime boundaries of the U.S. and metadata, which describe NOAA’s National Baseline processes, are available from http://nauticalcharts.noaa.gov/cdsl/mbound.htm The combined baseline file was reformatted as required for input into the CARIS Limits and Boundaries Program. Equidistant lines were then projected by CARIS using the EQUIDISTANT LINE tool. Coordinates for these lines were export from CARIS to ascii files which were reformatted as needed for input to ArcInfo with the GENERATE command. PROJECTDEFINE was used to define the coordinate system, and BUILD was used to build topology. Finally the ARCSHAPE command was run to convert to a shape file.
