In their insightful article on Hydro International, Łukasz Janowski, Paweł Tysiąc, and Gottfried Mandlburger delve into the immense potential of airborne bathymetric LiDAR and RIEGL technology to revolutionize hydrographic surveying. They explore its applications in coastal zone management, floodplain analysis, and navigation safety, underscoring its indispensability in modern hydrographic surveys.

RIEGL is proud to highlight the transformative technological capabilities of the VQ-840-G airborne bathymetric LiDAR system, which is setting new standards in hydrographic surveying. Utilizing a pulsed green laser, our systems penetrate water surfaces to deliver precise data on underwater terrain, essential for environmental management, infrastructure planning, and disaster preparedness.

Our advanced LiDAR technology ensures minimal absorption and scattering in clear water, enabling accurate measurement of submerged features. The integration of a laser scanner, GNSS, and IMU in our systems guarantees high-resolution, geospatially accurate datasets.
