CASANC is a polygon coverage showing the offshore boundaries of the national marine sanctuaries (NMS) off central California: Monterey Bay NMS, Cordell Bank NMS, and Gulf of the Farallones NMS and the adjacent coastline.
This is one of a collection of digital files of a geographic information system of spatially referenced data related to the USGS Coastal and Marine Geology Program "Monterey Bay National Marine Sanctuary Project" <http://walrus.wr.usgs.gov/mbms>. The data were collected and analyzed between 1994 and 2000.

This is a Vector data set. It contains the following vector data types (SDTS terminology):
Planar coordinates are encoded using coordinate pair
Abscissae (x-coordinates) are specified to the nearest 103.9406942649
Ordinates (y-coordinates) are specified to the nearest 103.9406942649
Planar coordinates are specified in Meters
The horizontal datum used is North American Datum of 1983.
The ellipsoid used is GRS1980.
The semi-major axis of the ellipsoid used is 6378137.0.
The flattening of the ellipsoid used is 1/298.257.
The polygons in the coverage CASANC are identified
in the attributes SANC_ID and SANC_NAME:
SANC_ID is a 2-letter code for sanctuary polygons
cb = Cordell Bank
fi = Gulf of the Farallones
mb = Monterey Bay
SANC_NAME is the full sanctuary name
Cordell Bank National Marine Sanctuary
Gulf of the Farallones National Marine Sanctuary
Monterey Bay National Marine Sanctuary
The lines in the coverage CASANC are identified in
the attribute LTYPE:
LTYPE = 'coast' for coastline arcs; 'sanc' for sanctuary boundary
