Multipurpose Marine Cadastre Map
Viewer
This online interactive map viewer has integrated
submerged lands information consisting of legal,
property ownership (cadastre), physical, biological,
and cultural information from multiple agencies in a
common reference framework. Users can create, view,
and print maps from this free, easy to use viewer,
or can directly link these GIS data layers (web map
services) into their own GIS applications.
Click
on the
Mapping Viewer or
use the left navigation button labeled Map Viewer

OPD, SOBD, CBD, & Lease Map Diagrams
Official Protraction Diagrams (OPDs) and Lease Maps
show the OCS block grids and other boundaries for a
given area. Supplemental Official Block Diagrams (SOBDs)
are created for individual blocks which are
intersected by offshore boundaries. The zip files
may contain both current and historic SOBDs. The
older SOBDs are provided for historical reference,
but all future activities will be based on the most
current SOBDs. Composite Block Diagrams (CBDs) show
NAD 27 lease information portrayed on the NAD 83
cadastre, or show other boundaries that have changed
over time. Not all OPDs have SOBDs or CBDs
associated with them.
Click on the individual Region names:
Atlantic,
Gulf,
Pacific,
Alaska, or use
the left navigation buttons to access the diagrams
for each Region.
