Hydrographic

Geodime regularly undertakes lake and river bed, and inshore hydrographic surveys for such purposes as reserve estimates for underwater aggregate deposits, volume calculations for dredging operations and beach profiling.

We routinely use bathymetry derived from SONAR and topography derived from photogrammetry or LIDAR, to provide highly accurate combined models of water bodies and the surrounding terrain.

We have a variety of craft at our disposal equipped with differential GPS and SONAR, enabling the fast and accurate mapping of underwater bathymetry, with plans to Ordnance or Chart Datum and in any format including HEC-RAS.

Our surveyors hold the RYA Powerboat Level 2 qualification, and are highly experienced in the different challenges that accompany the monitoring of water bodies.
