These layers are available in the ArcView shapefile format and contain various interpretive information for the study area. There are four raster image files contained on this disk. Although some programs do not interpret the additional geotiff tags, the image may still be viewed by any program capable of viewing a 'tiff' image. For those software packages that do not process the geotiff tags properly and where the user wishes to georeference the images, a separate georeference report, which contains the necessary information, is available for each image. Supporting metadata and spatial georeferencing information for the individual files are supplied from the additional information column.
Imagery is displayed on white background.
Bathymetry shown in a gradiated pseudo-color table. Bathymetry shown in a stepped pseudo-color table. The purpose of archiving these two images as GRID files was to satisfy ESRI's view of differentiating grids and images. Though both are defined with a raster structure, the grid files are considered 'cell' based. In addition to their spatial location, each grid 'cell' corresponds to a specific characteristic of that site, such as acoustic reflectivity for the sidescan sonar mosaic or depth for the bathymetry.
