Bridging the gap between land and water with precision hydrographic surveying! This set-up is running a Trimble R10 GNSS and TSC7 controller paired with an external sonar system to capture real-time, centimeter-level bathymetric data. This integrated process ties every depth reading to the precise survey datum, generating highly accurate underwater surface models (DTMs) in Trimble Access and TBC. It’s the ultimate workflow for marine construction, volumetric analysis, and infrastructure inspecti
