  • Bathymetric Profiling Services

    The basic principle behind bathymetry is the use of acoustic waves (in the range 30 to 250kHz) to measure the water depth. A complete bathymetry system includes a vessel, an echo-sounder (analogue or digital) and a positioning system (DGPS or RTK). The depth information is geo-referenced in real time and recorded on a portable computer on-board ...
