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. 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.
Please acknowledge NOAA and the NOAA Ship RUDE as the originators of the data from which this data set was derived.

This GIS overlay is a component of NOAA Survey H11320, Rhode Island Sound GIS database and contains the completed sidescan sonar mosaic for the study area. This image has been enhanced for better viewing. 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.

An associated TIF world file was then created using LINUX 'vi'.
