QTCView is used with an incorporated depthfinder to create a sonar map of the bottom to the west of the Charles Island, in Long Island Sound in Connecticut waters. Two maps are created, one at 50 kHz and one at 200 kHz to compare the results. Video is being used to groundtruth the bottom type classifications identified by the sonar.
