RIEGL Topo-Bathymetric Airborne Laser Scanners

Especially developed for coastline and shallow water mapping and river surveying, RIEGL’s topo-bathymetric airborne laser scanners, the VQ-840-G and the VQ-840-GL, offer up to 2 Secchi depths water penetration. The lightweight VQ-840-GL is especially suited for UAV integration.

In 2024 the portfolio of RIEGL topo-bathymetric laser scanners has been further enlarged.

The RIEGL VQ-860-G High Performance Topo-Bathymetric Airborne Laser Scanner offers enhanced depth penetration in surveying inland and near shore waters for even more efficiency in bathymetric applications. The compact system offers a large operational envelope with typical flight altitudes from 75 m to 300 m above the water surface, while providing high spatial resolution resulting from measurement rates of up to 100 kHz and a high scanning speed of up to 100 scans/sec. It is ideal for integration into large drones or manned helicopters.

Additionally, the RIEGL VQ-840-GE – with its compact and robust design and further reduced in weight – is especially prepared for integration into UAVs. The sensor can optionally be offered with an integrated and factory-calibrated IMU/GNSS system and an optional camera.
