High-density, short-time, low-cost, and safe surveying is possible.
We use a remote-controlled boat for depth measurement to measure water depth with sonar (sound waves). In advance, we discuss the survey area and density, and conduct a field survey as needed.
It is possible to obtain the shapes of the seabed, lakebed, riverbed, etc., as 3D point cloud data.
"Multi-beam bathymetric surveying" uses a "multi-beam echo sounder" that emits sound waves in a fan shape to conduct area-based measurements (swath bathymetry), allowing for the measurement of the seafloor, lakebed, riverbed, etc., as 3D point cloud data, and enables the determination of 3D shapes and changes. It can measure vast areas in a short time, and because it can measure terrains between survey lines that were difficult with single-beam echo sounders, detailed contour maps can be created. 【Features】 - The echo sounder is the "iWBMSH" multi-beam echo sounder manufactured by NORBIT. - The sonar adopts a curved array method, allowing the swath width to be changed arbitrarily between 7° and 210°. - The sonar, motion sensor, and surface sound velocity meter are integrated, making the onboard equipment compact, resulting in fewer wiring connections, reduced installation time, and improved safety during onboard operations. - The bathymetric sonar is mounted on the side of the survey vessel. It can be installed on small outboard motor boats or vessels weighing around 20 tons using single pipe and dedicated fixtures. - A terrestrial 3D laser scanner "iLIDER" is used to simultaneously measure the land portion. *For more details, please refer to the PDF document or feel free to contact us.
