DATA: imagery and vector information


This CD-ROM contains archives of the GLORIA sidescan sonar mosaic and it's geologic interpretation.  The data on this disk are stored either in raster or vector forms.  Raster data are stored in geotiff format to ease importing of the raster imagery into various GIS software and/or image analysis software.  The vector data consist of line information (bathymetry contour lines), point data (Gulf of Mexico features names), and polygon coverages of the geologic interpretion.  These data layers are stored in ESRI's ArcView shapefile format.
