Precision underwater terrain mapping using single-beam and multi-beam sonar systems for lakes, rivers, canals, estuaries, and coastal waters. Florida's extensive waterway network demands accurate sub-surface data for dredging design, flood control modeling, sediment management, and marine construction — we deliver it with survey-grade accuracy.
A bathymetric survey measures and maps the depth and underwater topography of a water body. Using acoustic transducers (sonar), our survey vessel transmits sound pulses and records the return time to calculate depth at thousands of points per minute. Combined with precise GNSS positioning, every depth measurement is georeferenced and integrated into a continuous underwater terrain model.
EA Mapping integrates bathymetric surveys with terrestrial topographic data to create seamless above-and-below-water surface models — essential for flood routing, hydraulic modeling, dredging volume calculations, and coastal infrastructure design.
