This is a Raster data set. It contains the following raster data types:
Planar coordinates are encoded using row and column
Abscissae (x-coordinates) are specified to the nearest 10.000000
Ordinates (y-coordinates) are specified to the nearest 10.000000
Planar coordinates are specified in meters
The horizontal datum used is North American Datum of 1983.
The ellipsoid used is Geodetic Reference System 80.
The semi-major axis of the ellipsoid used is 6378137.000000.
The flattening of the ellipsoid used is 1/298.257222.

2.0 meters. Please see text of Miscellaneous Field Investigation MF-2393.
According to the Pelagos report, the Raytheon echo sounder used had an accuracy of 0.06 meters (0.2 feet) and their digitizing system had an accuracy of 0.08 meters (0.25 feet). Their field calibration steps were designed to meet or exceed the manufacturer's stated accuracy, bringing accuracy of depth measurements to within than 0.15 meters (0.5 feet).
The ArcInfo GRID was generated from digitized contours of the hard-copy maps and not the actual 29,650 survey points. Therefore, the accuracy of the ArcInfo GRID relies upon the original cartography work done by Pelagos and the data processing performed thereafter. Additional information can be found in the text of Miscellaneous Field Investigation MF-2393.
