Our team tested a new payload for the Velos Rotors V3 this week. The RIEGL VQ-840-GL is a fully integrated, compact airborne laser scanner for combined topographic and bathymetric surveying. It collects laser range measurements for high-resolution surveying of underwater topography with a narrow, visible green laser beam emitted from a pulsed laser source. Subject to clarity, at this wavelength the laser beam penetrates water enabling measurement of submerged targets.
Applications for this UAV solution include:
- Coastline and Shallow Water Mapping
- Surveying for Hydraulic Engineering
- Hydro-Archaeological-Surveying
- River Surveying
- Repeated Survey of Water Reservoir
We conducted four test flights over two days and flew the same mission every time. The dataset was around 20 GB in size per set.
Additional details about the automatic mission:
- 100 m altitude above ground level
- 60 m line separation distance
- 200.000 sq meters survey area
- 5 km total length of the mission
