Description:
Abstract:
This data set contains baseline tangent lines and bay closing lines in ESRI Arc/Info export and Arc/View shape file formats for the MMS Atlantic Region. Baseline tangent line segments and bay closing lines are used by the MMS to calculate the Submerged Lands Act (SLA) boundary line and the Limit of '8(g) Zone' boundary line. These lines may also be used to calculate other offshore boundary lines. A second file containing baseline points is also available.
Purpose:
Baseline tangent lines 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.

Process_Step:
Process_Description:
The source data for the baseline tangent lines 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 and tangent lines contribute to the various projected lines MMS uses.
