RIEGL – Topo-Bathymetric Airborne Laser Scanners and Systems

RIEGL is a leading provider of cutting-edge Waveform-LiDAR technology in airborne, mobile, terrestrial, and UAV-based laser scanning.

For the hydrographic context, there is a range of airborne as well as boat-based RIEGL systems for high resolution surveying of on-shore topography or any infrastructure and vegetation above the water surface.

For airborne combined topo-bathymetric applications, RIEGL offers the fully integrated laser scanning systems VQ-880-G II and VQ-880-GH. Providing a water penetration of 1.5 Secchi depths, they are ideally suited for efficient large-area coastline and shallow water mapping, river bed profiling, measurement of aggradation zones, hydro-archaeological surveying, etc.

These turnkey surveying systems include a high-end IMU/GNSS unit and up to two cameras (e.g., RGB and IR) and are fully calibrated off-factory. The integrated infrared laser scanner complements the data from the green laser scanner and supports the detection of the water surface. The compact and robust housing is compliant with typical aircraft hatches and stabilized platforms. The VQ-880-GH’s form factor with reduced height is specifically optimized for helicopter integration.

Especially to be used with both manned and unmanned carrier platforms with limited payload capacity, the compact RIEGL VQ-840-G Topo-Bathymetric Airborne Laser Scanner provides more than 2 Secchi depths water penetration and high spatial resolution due to a measurement rate of up to 200 kHz and selectable laser beam divergence. It’s operational versatility and straightforward integration options make this system the ideal companion for complex, high-detail surveys.

The RIEGL VQ-840-GL Topo-Bathymetric Airborne Laser Scanner now comes in a new design. Maintaining the proven form factor, internal redesign and the additional use of lightweight structural components enable a weight reduction of 20 % to 9.8 kg (20 lbs). That makes the sensor even more suitable for UAV integration and UAV-based applications.

RIEGL Mobile Laser Scanning systems are designed to be easily integrated to moving platforms, so also on boats. Their millimeter precision paired with high grade IMU/GNSS units enables precise point cloud geo-referencing for a variety of shipborne surveying applications, such as mid-range shoreline mapping as well short-range applications that result in feature-rich digital twins of e.g., harbor infrastructure, bridge structures or river banks.
