Following are the source area estimates and the preliminary GIS area estimates. Please note that the Marine Protected Area database was created for general mapping planning and policy applications. The GIS was created utilizing the best source data available. The accuracy of this database has yet to be assessed, and no claim is made regarding its correctness. Neither the RSRU ,the University of California Santa Barbara, California Sea Grant College, nor the University of California Cooperative Extension Program shall be held responsible for improper uses or inadequate findings as a result of the use of this database.
Differences could be due
to;
*Lack of clearly defined source data, including inaccurate boundary descriptions
and unintelligible legal descriptions.
* Unavailability of metadata such as county zoning records.
* Errors introduced by interpolation and extrapolation from general sketches.
*Unknown methods used for original source area estimations. In many cases the
method used by the sources to manually measure areas is not known, or the original
projection that they used is not known. Also, the legal boundary interpretation
is not known at many sites (e.g. , many ASBS boundaries are described as to
the 1000' or 100' Isobath, whichever is greater. In these instances we used
the greater distance which was always the 100' Isobath).
