Digital Offshore Cadastre (DOC) - Pacific83 - Baseline Tangent Lines

This data set contains baseline tangent lines and bay closing lines in ESRI Arc/Info export and Arc/View shape file formats for the BOEM Pacific Region. Baseline tangent lines and bay closing lines are used by the BOEM 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.
