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 ImagesA 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. All the SOBDs for a given OPD are zipped into a single file
for downloading. The zip files will contain the most recent version,
but older historic versions may also be included for reference.
For the purpose of future Lease Sales always be sure to use the
most recent version.
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. 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. (If they are compressed they will have a .Z
extension.) If the file transfer process has changed the upper case
Z to lower case z you might need to change it back to upper case Z
before the UNIX uncompress utility will recognize the
file.
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.
