Bathymetry with drones

Depth models and inspection of basins and small bodies of water

The outstandingly economical measurement of small bodies of water. Determination of the bed course through sediments - even in inaccessible places.

Benefit immediately:

Lowest costs compared to alternative measurement methods
Can be used quickly on site, no preparatory work necessary
Area-wide and centimeter-accurate depth models
Even in inaccessible areas such as reed beds
Direct determination of sediment inputs without zero measurement or plans

Remote-controlled sensors for efficient water measurement

From the air: depth measurement

Sediment surfaces in inaccessible places

From the air: sounding

Water bed in inaccessible places

On the water: sonar measurement

Area-wide measurement of the sediment surface

On the water: sounding

Area-wide measurement down to the river bed

In the water: depth measurement

Spot depth measurement of the sediment surface

From the shore:
Sounding

Spot measurement down to the water bed

The measurements from all sensors are documented to the nearest cm via GNSS/GPS-RTK and consolidated, checked for plausibility and further processed in a shared database

Project examples

Complete survey of rainwater retention systems (Hesse)

Along federal highways, 11 facilities were completely recorded with orthophoto, 3D model, 2D CAD site plan, sediment determination and video overview
