This is a Raster data set. It contains the following raster data types:
Horizontal positions are specified in geographic coordinates, that is, latitude and longitude. Latitudes are given to the nearest 0.000000. Longitudes are given to the nearest 0.000000. 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.

This GIS overlay is a component of the H11321 Survey, Rhode Island Sound, GIS database and contains the completed enhanced sidescan-sonar mosaic for the study area. Light tones represent relatively harder returns, higher backscatter, and generally coarser sediments. Dark tones represent relatively softer returns, lower backscatter, and generally finer grained sediments.
National Oceanic and Atmospheric Administration, raw sidescan-sonar data.
