Bathymetry & Marine Survey
See below the surface. No boat needed.
We map the bottom of reservoirs, lakes, rivers and coastal areas with a drone-mounted echo sounder. Accurate depths, sediment volumes and 3D models, even in shallow or hard-to-reach water.

What you get
Depth maps and contoursBottom surface maps with depth contours at the scale you need.
3D bottom models and DEMUnderwater terrain as a 3D model, merged with the shoreline from LiDAR.
Cross-sectionsProfiles across the water body for design and engineering.
Sediment volumesSediment layer thickness and quantities for cleaning and dredging.
Dredging monitoringRepeat surveys to compare before and after and verify the works.
Survey reportHydrographic report with volumes and coverage, ready to submit.
Why drone bathymetry
Faster, safer and closer to the shore.
A drone carries the echo sounder over the water, so there is no boat to launch and no crew in the water. We reach shallow zones, areas near breakwaters and closed reservoirs where boats cannot go.
Lower cost than traditional surveys, minimal impact on the water and aquatic life, and data you can act on right away.
