SPH Engineering has launched a new product to make bathymetric surveys of inland and coastal water.
The system — an unmanned aerial vehicle (UAV) integrated with an echo sounder — is time- and cost-efficient. It is suitable for mapping, measuring and inspecting tasks as well as environmental monitoring.
The system allows field workers to collect data with high accuracy quickly. It is easily transported, quickly deployed and twice as cost-efficient as traditional methods.
The UAV/echo sounder system can be operated in hard to reach locations, and unsafe or hazardous environments. Locations not reachable by foot or that are dangerous for a human (steep coasts, mining pits, contaminated waters, terrain obstacles, etc.) as well as waters of ponds, lakes, and canals can be reached by the drone.
“Since autumn 2018 we have been getting bathymetry-related requests,” said Lexey Dobrovolskiy, CTO of SPH Engineering. “Analyzing about 150 inquiries, we have come to the conclusion that a drone-based solution could open a new business opportunity for drone service companies to do bathymetry surveys of coastal and inland water, especially those for industrial needs.
“Compared with a standard approach using a boat or an unmanned surface vehicle, a drone could save a lot for its user,” Dobrovolskiy said. “An echo sounder itself could be integrated into a client’s drone with no need to purchase additional equipment. Moreover, it is small and easy to transport and operate. At the same time, such research method guarantees data accuracy and employee safety.”
