Geographic
Information System (GIS)
Data and Maps
The MMS Mapping & Boundary Branch performs mathematical
offshore boundary location computations and prepares Official
Protraction Diagrams (OPDs),
and Supplemental Official OCS Block Diagrams (SOBDs)
depicting OCS Block information, the Submerged Lands Act Boundary (aka -
State Seaward Boundary), Limit of "8(g) Zone", the Continental Shelf Boundary
(CSB) which marks the limit of U.S. jurisdiction for offshore mineral development, and corresponding area
measurements. The analytical procedures employed and the computer
programs utilized to perform various offshore boundary geometric
computations are described in
OCS Report MMS
99-0006.
OPD Images
A standard OPD is 1 degree in latitude by 2 degrees in
longitude (at lower latitudes: 0 - 48 degrees). At higher latitudes (48 - 75 degrees) such as
Alaska and northern Washington, OPDs are 3 degrees wide.
OPD limits usually approximate
the standard 1:250,000 scale U.S. Geological Survey topographic map series.
The OPDs are numbered using the United Nations International Map of the World Numbering System.
OPD names usually coincide with standard topographic sheet names when diagrams include land areas.
OPD sheet names relate to land features, or to hydrographic features contained within the
limits of the diagram. Shoreline planimetric detail is shown when it falls within the limits
of a diagram. Older OPDs were prepared on mylar with manual cartographic methods and then
scanned into Adobe .pdf files. Newer OPDs were prepared electronically and converted to Arc Info
.gra files and Adobe .pdf files
A Supplemental Official OCS Block Diagram (SOBD) is prepared for each block intersected
by an offshore boundary (Submerged Lands Act Boundary, Limit of "8(g) Zone", National
Marine Sanctuaries, etc.). Note that not all OPDs contain such boundaries, therefore not
all OPDs have SOBDs associated with them.
Image File Formats
The most current approved revision for each Pacific Region OPD and SOBD may be viewed and
downloaded from the list below. OPDs are offered in both Arc/Info Graphics File (.gra) format,
and Adobe (.pdf) format. SOBDs are available as Adobe (.pdf) files that have been compressed
with PKZIP. Free decompression utilities may be downloaded
here. Adobe (.pdf) files may be viewed with the free
Adobe Acrobat reader.
The various boundaries are offered as GIS files in both Arc/Info export (.e00) format
and as Arc View shapefiles. Shapefiles can also be viewed
with the free Arc Explorer viewer.
The shape files have been zipped with Pkzip. The .e00 export files have been compressed with the
UNIX "compress" command. Use the UNIX "uncompress" utility or the
free
gzip.exe dos utility.
Note: The precise coordinates of a GIS file can be altered slightly by various GIS functions.
For that reason, these GIS files are not an Official Record for MMS offshore boundaries. Only the
coordinates shown on Official OPDs and SOBDs constitute an Official Record for offshore
coordinate values.
All coordinates are in NAD 83. Pacific Region leases and cadastre data from before 1997 were done on
the North American Datum of 1927 (NAD 27). These new NAD 83 files do not represent a conversion, but rather a complete regrid.
For further details see: Project Plan for Implementing NAD 83 in the Minerals Management Service
Part I: Responsibilities and Timeframes,
Part II: Technical Aspects of Implementation, and
Summary Status Report.
The files below may also be ordered on CD. Contact
Bob Johnson, or call (303) 231-3033.
