- Abstract:
-
This data set contains the Submerged Lands Act boundary line (also
known as State Seaward Boundary (SSB) and Fed State Boundary) in ESRI
Arc/Info export and Arc/View shape file formats for the MMS Alaska
Region. The SLA defines the seaward limit of a state's submerged lands
and the landward boundary of federally managed OCS lands. In the MMS
Alaska it is projected 3 nautical miles offshore from the baseline. The
digital SLA line is shown only in areas where an official baseline has
been established. Further information on the SLA and development of
this line from baseline points can be found in OCS Report MMS 99-0006:
Boundary Development on the Outer Continental Shelf.
Because GIS projection and topology functions can change or
generalize coordinates, these GIS files are NOT an OFFICIAL record for
the exact Submerged Lands Act Boundary.
- Purpose:
-
The Submerged Lands Act boundary line and other cadastre
information the MMS produces are generated in accordance with 30 Code of
Federal Regulations (CFR) 256.8 to support Federal land ownership and
mineral resource management.
- 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
will include digital images of MMS data 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.

- Logical_Consistency_Report:
-
Coordinates for OCS blocks, baseline, and
projected boundaries are calculated quantities and have been defined to
be correct to 3 decimal places of a meter.
- Completeness_Report:
-
The NAD83 Submerged Lands Act (SLA) boundary line in the
MMS Alaska Region is shown where it was projected from official baseline
points.

-
Coordinates for points forming
the Submerged Lands Act boundary line are calculated values to
3 decimal places of a meter in the TIMS database. However, GIS
functions which build topology, change projections, etc. may degrade
coordinate values. Furthermore, most of the SLA boundary consists of
true arcs, but has been approximated in these GIS files by straight
line segments. For these reasons, these GIS files are NOT an OFFICIAL
record.

From the GIS Coverages section of the website
html page, click on the Arc/Info .e00 Export file you wish to
download. The downloaded file will need to be uncompressed. In a
UNIX environment use 'uncompress filename'. In a DOS environment
use 'gzip -d filename'. The resulting file will be an Arc/Info
export data file (filename.e00).
