Here’s a free sample chart that shows how we use side-scan sonar to map out part of the Elbow in federal waters.
We use high-resolution side-scan sonar data to search for cool structure. When we find something, we mark the spot, give it a name, and then trace out the structure with simplified lines. Then we convert these lines and points into electronic chart files that can be downloaded directly into your boat’s GPS.
This free preview is only available in Google Earth KMZ format. For GPS/Chartplotter formats, check out our full Elbow chart.
