Webinar | Advanced methods of bathymetric data collection with UAV

Bathymetry is the measurement of the depth of water in oceans, rivers, or lakes. The standard measurement tool for bathymetry is echo sounding, and the survey process involves the use of a ship, boat, or unmanned surface vehicle (USV) as a platform for the sensor.

Sometimes, the use of a boat can be complicated, especially in the case of small or hard to reach rivers and lakes. The use of USV is not feasible in every situation either.

  • Firstly, it is necessary to have a good point of entry to the water for deployment/recovery.
  • Secondly, it may be impossible to use USV in shallow lakes with lots of seaweed.
  • Last but not least, in many cases, USV should be big enough to resist the waves and a big car may be necessary to transport it.

An alternative is to fly a drone (UAV) to carry the echo sounder. A drone is compact and easy to transport and deploy. Drones also have a high precision of following planned survey lines and can be used in any place where there is at least a small area for take-off and landing near the surveyed water surface.

During the webinar, we cover

  • Benefits and drawbacks of using echosounder with a drone
  • Demonstration of all components of the bathymetric UAV system
  • Bathymetric survey mission planning and simulation
  • Data processing using Eye4Software Hydromagic.
