- Description:

- Abstract:
-
This data set contains baseline points in ESRI Arc/Info export and
Arc/View shape file formats for the BOEM Pacific Region. Baseline points
are used by the BOEM to calculate the Submerged Lands Act (SLA) boundary
line and the Limit of 8(g) Zone boundary line. These points may also
be used to calculate other offshore boundary lines. A second file
containing bay closing lines and other tangent lines is also available.
- Purpose:
-
Baseline points and other cadastre information the BOEM 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 BOEM is making its existing cadastre data
available at <http://www.boem.gov/Oil-and-Gas-Energy-Program/Mapping-and-Data/Index.aspx> and on CD-ROM. These data
will include digital images of BOEM 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.

-
- Process_Description:
-
The source data for the baseline points are
generally NOAA nautical charts, topographic sheets and hydrographic
surveys. Where the source was on NAD27, the latest version of NADCON
was used to transform the coordinates to NAD83. Additionally, if
available, HARN adjustments are made. Points along the coastline and
offshore islands and offshore rocks which may contribute to the
baseline are selected and their location digitized and placed in the
TIMS Block and Boundary database. Points are selected using
criteria from the Law of the Sea and various U. S. Supreme Court
decisions. Points are based on mean lower low water (MLLW) if shown
on the NOAA source. In the absence of the MLLW line, the mean high
water line was used. The elevations of offshore rocks awash are
indicated if known. Field reconnaissance was conducted on other
rocks awash to determine if they were bare at predicted low tide.
In-house computer programs are used to determine which points
contribute to the various projected lines BOEM uses.
