Abstract

For the past decade, SHOALS (Scanning Hydrographic Operational Airborne Lidar Survey) has proven to be an efficient and cost-effective means for large-area coastal mapping projects. However, its capabilities in the rapid reconnaissance of small underwater obstructions have been less appreciated, despite a demonstrated history of successful detection and spatial identification. This paper discusses SHOALS‘ object detection capabilities in light of the recent developments in object detection algorithms, with multiple situation studies to illustrate its overall performance and latest enhancements. Various aspects of object detection using airborne bathymetric lidar are discussed to highlight the challenges and advantages of using SHOALS for rapid reconnaissance of small underwater obstructions.
