The Gulf of Mexico GIS database is intended to organize and display USGS held data and provide on-line (WWW) access to the data and/or metadata. Purpose: This GIS data layer is a 250 m version of the composite Gulf of Mexico GLORIA sidescan sonar image mosaic that is in a geographic projection using the WGS84 datum. The GLORIA imagery was collected during 1982 and 1985 and covers 490,563 km2 of the Gulf of Mexico in water deeper than approximately 300 m. A discussion of these data can be found in EEZ Scan 85 Scientific Staff (1987).

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 been radiometrically enhanced for better viewing.
