This is a Vector data set. It contains the following vector data types (SDTS terminology):
Horizontal positions are specified in geographic coordinates, that is, latitude and longitude. Latitudes are given to the nearest 0.000001. Longitudes are given to the nearest 0.000001. Latitude and longitude values are specified in Decimal degrees.
The horizontal datum used is D_WGS_1984.
The ellipsoid used is WGS_1984.
The semi-major axis of the ellipsoid used is 6378137.000000.
The flattening of the ellipsoid used is 1/298.257224.
Sequential unique whole numbers that are automatically generated.
Coordinates defining the features.
| Value | Definition |
|---|---|
| boulders | Rocky area of the sea floor where avarage gravel exceed 256 mm in diameter |
| bedforms | Large bedforms (sand waves and megaripples) whose relief exceeds 20 cm |
| shell beds | Densely packed, grain-supported, bioclastic layers composed largely of mollusk shells and shell fragments |
