This is a Raster data set. It contains the following raster data types:
The map projection used is Mercator.
Planar coordinates are encoded using row and column
Abscissae (x-coordinates) are specified to the nearest 250.000000
Ordinates (y-coordinates) are specified to the nearest 250.000000
Planar coordinates are specified in meters
The horizontal datum used is D_Clarke_1866.
The ellipsoid used is Clarke 1866.
The semi-major axis of the ellipsoid used is 6378206.400000.
The flattening of the ellipsoid used is 1/294.978698.
Public domain data from the U.S. Government are freely redistributable with proper metadata and source attribution. The U.S. Geological Survey (USGS) must be referenced as the originator of the dataset in any future products or research derived from these data.

There are no attributes associated with the GeoTIFF image.
Primary navigational control for this survey was by Loran-C supplemented by satellite navigation. Accuracy of location of the navigation fixes is estimated to be better than 100 meters.
All available imagery were used to create this mosaic. Data were acquired during a single cruise using the 6.5 kHz GLORIA sidescan-sonar system and a 45 km total swath width.
