    360 Degree Acoustic Imaging (Sector Scan)

    360-degree acoustic imaging is a great tool to investigate the conditions of the underwater portion of railroad bridge piers.  Also known as a sector scan, these tools can create detailed images in water conditions where there is zero visibility.  By stitching several of the images together, a complete picture of the underwater portion bridge pier, cribbing structure, or cellular structure can be created.  This, in turn, can be combined with above-water digital photography to create a complete image of the entire structure. 

    It is also effective in gathering images of the river bottom to monitor scour conditions by changing the orientation of the survey head.  This is a great tool to use in combination with dive inspections to get the information you need on your critical infrastructure!
