A laska Cadastral Data

Geographic Information System (GIS) Data and Maps

Regional Mapping Data

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), 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

SOBD Images

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.

CBD Images

Composite Block Diagrams (CBDs) show NAD 27 lease information portrayed on the NAD 83 cadastre, or show other boundaries that have changed over time. Not all OPDs have CBDs associated with them.

SOLD Images

SOLD’s identify areas within a block or several adjacent blocks that have been combined into a single bidding unit for a specific lease sale. The diagram includes boundary intersections, baseline arc centers, and areas. Not all OPDs have SOLDs associated with them.

Image File Formats

OPDs SOBDs, CBDs, and SOLDs may be viewed and downloaded from the list below. OPDs are offered in Adobe (.pdf) format. OPDs completed after 1996 are also available in Arc/Info Graphics File (.gra) format. SOBDs, CBDs, and SOLDs are available as Adobe (.pdf) files that have been compressed with PKZIP. The free pkunzip utility may be used to uncompress them. Adobe (.pdf) files may be viewed with the free Adobe Acrobat reader.

GIS Files

The various boundaries are also offered as GIS files in both Arc/Info export (.e00) format, and as Arc View shapefiles. Shapefiles can be viewed with the free Arc Explorer viewer. The shape files have been zipped with Pkzip. Some .e00 export files have been compressed with the UNIX "compress" command. (If they are compressed they will have a .Z extension.) Use the UNIX "uncompress" utility or the free uncomp.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, CBDs, and SOBDs constitute an Official Record for offshore coordinate values.

Note: OPDs have not yet been published for for all Alaska offshore areas and only the current versions of published OPDs are available from this site. Please contact the Alaska Region if you are looking for NAD 27, or older superseded NAD 83 versions.

All coordinates are in NAD 83. Alaska Region leases and cadaster data from before 1994 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:

The files below may also be ordered on CD. Contact Bob Johnson, or call (303) 275-7186.
