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.

The strengths of LiDAR technology in a hydrographic context are the collection of seamless data sets that span the land/water interface, enabling the survey of topography both above and below the water surface.

In coastal environments, Airborne LiDAR Bathymetry (ALB) is used for highly efficient mapping of large areas as well as for detailed underwater surveys in applications like survey of archaeological sites or for the detection of floating objects. Applications in inland water environments include natural habitat monitoring of rivers and lakes, as well as survey of artificial waterways.

RIEGL provides a product range of compact ALB sensors for different platforms and different use cases. Prepared for optional integration with high-precision IMU/GNSS systems and digital cameras, RIEGL ALB systems are configured tailored to carrier platform and application scenario.

The low weight and compact design of the topo-bathymetric airborne laser scanners RIEGL VQ-840-G and RIEGL VQ-840-GL allow for integration of these systems on smaller aircraft and UAVs – ideal for detailed data acquisition in smaller-scale applications that need to be carried out at shorter intervals, such as coastal erosion monitoring, surveying port infrastructure or rivers at risk of flooding. These scanners provide 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.

The RIEGL VQ-840-GE topo-bathymetric scanner – further reduced in weight and providing up to 2 Secchi depths – is the ideal solution for integration with drones.

For integration with crewed helicopters, fixed-wing aircraft and larger UAVs with appropriate payload capacity, the RIEGL VQ-860-G is RIEGL’s latest ALB system with an even enhanced water penetration capability of 2.5 Secchi Depths. Used in flight altitudes from 75m to 300m, the VQ-860-G meets the requirements of challenging survey mission while at the same time offering high productivity.

Additionally, to provide even higher resolution for the landscape on shore or any features above the water surface, topo-bathymetric data can be merged with LiDAR data acquired by terrestrial laser scanning or mobile laser scanning. RIEGL Mobile Laser Scanning Systems are designed to be easily installed on any vehicle on land or water. Their millimeter precision paired with high grade IMU/GNSS units enables precise point cloud geo-referencing. Complementing bathymetric data with high resolution scan data of terrain or structures above the water extends the usability of the results for a variety of applications, like for example infrastructure maintenance, harbor development, or erosion monitoring.
