Description:

Abstract:: This data set contains the Limit of '8(g) Zone' line in ESRI shapefile; format for the BOEM Atlantic Region. The '8(g) Zone' lies between the; Submerged Lands Act (SLA) boundary line and a line projected 3 nautical; miles seaward of the SLA boundary line. Within this zone, revenues are; shared with the coastal state(s).; Because GIS projection and topology functions can change or generalize; coordinates, these GIS files are considered to be approximate and are; NOT an OFFICIAL record for the exact Submerged Lands Act Boundary. The; Official Protraction Diagrams (OPDs) and Supplemental Official Block; Diagrams (SOBDs) serve as the legal definition for offshore boundary; coordinates and area descriptions.
Purpose:: The Limit of '8(g) Zone' boundary line 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. These data include; Official Protraction Diagrams (OPDs), and Supplemental Official OCS Block; Diagrams (SOBDs) in pdf format, and digital spatial data in ArcGIS; shapefile format.

Data_Quality_Information:

Logical_Consistency_Report:

The file is believed to be free of topologic errors.

Completeness_Report:

The entire NAD83 Limit of '8(g) Zone' boundary line in

the BOEM Atlantic Region is shown.

Positional_Accuracy:

Horizontal_Positional_Accuracy:

Horizontal_Positional_Accuracy_Report:: Coordinates for points forming; the Limit of '8(g) Zone' boundary line are calculated to 3 decimal; places of a meter in the TIMS database. However, GIS functions which; build topology, change projections, etc. may alter coordinate; values. Furthermore, most of the Limit of '8(g) Zone' boundary; consists of true arcs, but has been approximated by these shapefiles; with straight line segments. For these reasons, these shapefiles are; considered to be approximate and are NOT an OFFICIAL record.
