Description:
Abstract:
From October 22 to November 22, 1985 the U.S. Geological Survey (USGS) conducted a single to survey to ensonify the Cayman Trough. The survey took place over the coastal region of the spreading ridge and along one line to the eastern extremity of the Trough. As in earlier EEZ reconnaissance surveys, the USGS utilized the GLORIA (Geological LOng-Range Inclined Asdic) sidescan-sonar system to complete the geologic mapping. The collected GLORIA data were processed and digitally mosaicked to produce continuous imagery of the sea-floor. Two digital mosaics of a 2 degree by 2 degree area with a 50-meter pixel resolution were completed for the Cayman Trough south of the Cayman Islands.
Purpose:
This remote sensing image of the sea-floor is a reduced-resolution (250-meter) composite mosaic of the 2 mosaics created from the Cayman Trough GLORIA sidescan-sonar data.

Process_Description:
Using the PCI Geomatics tool GCPworks, the 2 individual 50-meter mosaics were combined to create a composite overview of the Cayman Trough GLORIA data at a resolution of 250-meters. The individual full-resolution GLORIA mosaics with the white flood-filled background were mosaiced together to create a single reduced-resolution composite mosaic for the Cayman Trough. Individual mosaics were "dropped" into the composite database. No rubber sheeting or geometric corrections were applied to the mosaics. However, some mosaics were radiometrically enhanced to reduce the effect of the individual square boundaries and produce a more uniform overview image. The individual 23 mosaics were combined using a bi-linear resampling mode to reduce noise and blockiness.

Overview_Description:
Entity_and_Attribute_Overview:
There are no attributes associated with a GeoTIFF image. Image pixel values contain acoustic reflectivity values normalized to an 8-bit data range (0-255). Low-backscatter is represented by dark tones (low values) and high-backscatter is represented by bright tones (high values). These data have NOT been radiometrically enhanced.
