Online_Linkage: https://doi.org/10.3133/ofr00352 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.

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.

(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.
