EdgeTech, the leader in high resolution sonar imaging systems and underwater technology, mapped St. John’s Harbor in record time during the recent Canadian Hydrographic Conference.
During the on-water demonstrations, EdgeTech’s recently introduced 6205 Bathymetry System collected co-registered bathymetry and side scan sonar data in less than 3 hours. The processed data created a stunning bathymetric map of the complete harbor and the “Narrows” entrance to the harbor.
Traditional multi-beams used to map the harbor previously had taken considerably more time due to their narrow swath coverage. Multi-beam systems in their design are inefficient in shallow water due to the narrow 3 to 4 times water depth coverage.
Additionally, traditional multi-beam systems do not produce true side scan sonar data nor do they operate at simultaneous dual frequencies.
