Description:
Abstract:
This ArcView GIS layer is a 25 m version of the completed SeaMARC 1A 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:
Two sets images of the 25 m SeaMARC1A sidescan sonar data are available for the study area. One image set has been radiometrically enhanced for better viewing, and the other set has not been enhanced. This set is available for user's who wish to apply their own enhancements. Additionally, the images are available in both GEOTIFF and JPEG formats.

The individual individual swath files were processed using the Woods Hole Image Processing Software (WHIPS). The individual strips were processed to apply geometric (i.e. slant-to-ground range corrections) and radiometric corrections (i.e. beam correction shading).

Process_Description:
The SeaMARC 1A files that comprised the eastern half of the survey were transferred to the Woods Hole Field Center's MicroVAX-II computer system. This portion of the survey consisted of mostly straight line segments and were to be digitally mosaicked on this system. (The western portion were done a few months later with developing software). The MicroVAX-II computer system contained the Mini-Image Processing System (MIPS) software that was needed to map and digitally mosaic the data. To begin processing, the WHIPS data files were all converted to MIPS format.

Process_Step:
Process_Description:
As the individual swaths were mapped, they were geo-referenced to the base image, stenciled and mosaiced to the base. (The base was one swath that had been mapped and was selected as the master which everything would be registered with.) Control points were selected interactively to match features on the adjacent lines and a rubber sheeting procedures were applied to the mapped swaths to better align the images. Once registered, a stencil line was interactively drawn around the area of the line to be added. This stencil area was critical as it not only eliminated the unwanted area that was overlapping the adjacent lines but defined the area to be kept. Finally the registered, transformed and stenciled image was added to the base. These steps were repeated for each swath until the eastern mosaic was completed.

The SeaMARC 1A files that comprised the western half of the survey were mapped using the WHIPS software. This area of the survey consisted of several survey line segments. This software could handle curved line segments. The files were projected and mapped with a Mercator project and a Clarke 1866 spheroid to match the eastern portion.

Process_Description:
The converted WHIPS mapped swaths were stenciled and mosaicked with the MIPS software. This procedure is similar to the one outlined for the eastern portion of the survey. Control points were selected interactively to match features on the adjacent lines and a rubber sheeting procedures were applied to the mapped swaths to better align the images. Once registered, a stencil line was interactively drawn around the area of the line to be added. This stencil area was critical as it not only eliminated the unwanted area that was overlapping the adjacent lines but defined the area to be kept.
