    • Alaska NAD 83 Composite Block Diagram (CBD) Images

    Metadata Updated: October 29, 2023

    This data set contains Composite Block Diagram (CBD) images in Adobe pdf format for areas within the BOEM Alaska Region. Each CBD describes a single block within an Official Protraction Diagram (OPD) and shows the lines (Submerged Lands Act, Limit of "8(g) Zone", maritime boundaries and/or marine sanctuaries), NAD 27 leases, and NAD 27 boundaries which occur within that block and divide it into different areas. The CBD contains additional coordinates and area calculations for an individual block. These data are scanned images of the official paper CBDs produced by the BOEM.
