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_Step:

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.
