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 |
---|---|
Erosion | erosion or nondeposition characterized by high backscatter in the sidescan-sonar image and clusters of boulders indicating coarser grained sediment reflective of higher energy environments |
Sort_rework | sorting and reworking characterized by moderate backscatter in the sidescan-sonar imagery and the sea floor tends to be relatively smooth |
Cgbt | Coarse-grained bedload transport characterized by bathymetric highs and where there are sand waves |
Deposition | fine-grained deposition characterized by low backscatter in the sidescan-sonar imagery and typically occurring in part of the channel and bathymetric lows |

This data layer is a component of the H11322 Survey, GIS database and represents an interpretation of the sidescan-sonar mosaic for the study area. The interpretation can be used as an overlay for the mosaic image and shows the sedimentary environments of the study area such as erosion or nondeposition, sorting and reworking, deposition, and coarse-grained bedload transport.

Attributes have been visually checked by the compilers.
Navigation was by differential GPS.
Layer is complete as interpreted for these features.
Several shapefiles representing various features identified on the mosaic were combined to create this data layer. The layers were edited and processed in a consistent manner.
