Abstract:
This image is a 250m version of the composite Gulf of Mexico GLORIA sidescan sonar mosaic.
Purpose:
This GIS overlay is a component of the U. S. Geological Survey, Woods Hole Field Center's, Gulf of Mexico ArcView GIS database. 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.
Supplemental_Information:
The images, compos.jpg and compos.tif, have a black background surrounding the sidescan sonar mosaic.
The images, composw.jpg and composw.tif, have a white background surrounding the sidescan sonar mosaic.  For some display purposes, these images may be more suitable than images with a black background described above.
The Gulf of Mexico GLORIA sidescan sonar data were collected during 3 separate field cruise

    Raw imagery of GLORIA data may be retrieved from this CD-ROM. The user must note the number of pixels (samples) and lines contained in the data set to convert the raw imagery to a useable image format. The information can be found in the 'lbl' file associated with the image file.
    Process_Step:
    Process_Description:
    The 16 individual 50m GLORIA GEOTIFF images for the Gulf of Mexico were re-sampled to 250m and combined to create an overview digital mosaic of the Gulf of Mexico. Utilizing the PCI Remote Sensing software, an empty 'pix' file was defined. This file included the maximum extents of the GLORIA Gulf of Mexico survey area at a 250 m resolution. The images original projection (Albers Equal Area) and datum (Clarke 1866) was used to define the new image file. Utilizing the georeferencing information contained in the GEOTIFF images, the individual 50 m mosaic were placed in their proper geographic location in the new image via GCPworks. A bilinear resampling was applied to the image pixels to create the sub-sampled GLORIA mosaic.
