Highly accurate hydrographic surveys are of particular importance when it comes to monitoring and managing data of deep sea construction work, rivers or the effects of changing sea-levels, flooding, or coastal damage due to natural disasters. Leica Geosystems’ range of products like HawkEye III, Chiroptera and LiDAR Survey Studio represent the new generation of state-of-the-art airborne bathymetry.
HawkEye III: It is a combined airborne bathymetric and topographic multi sensor LiDAR system. With its high resolution and accuracy, HawkEye is the perfect tool for mapping, planning, maintaining and managing all national waters and coastal regions. It can do nautical charting of near shore and coastal zones and characterisation and mapping prior to infrastructure and constructional work.
The HawkEye III delivers full seafloor search. Point densities are easily configured by optimising survey altitude and airspeed. The survey parameters are easily adapted to the requirements of the survey and local water conditions.
CHIROPTERA: This airborne LiDAR system meets the highest demands for near-shore and coastal zone mapping. It is an integrated unit delivering harmonised land and sea data. With its high resolution and accuracy, it is the perfect tool for mapping, planning and managing the near-shore region. It can model sea level rise and global warming effects over time.
The Chiroptera delivers a point density of up to 1-2 points per square meter in the bathymetric channel and 10-30 points per square meter in the topography channel. The survey parameters are easily configured in the system settings and by selecting optimal flight levels and airspeed.
It is a cost-efficient sensor system for developing harmonised land and sea geographic datasets. In addition, combined LiDAR data can be used for simulation and studies of low-level land flooding and the effects of sea-level raise.
LiDAR Survey Studio: It is a state-of-the-art software tool for point-cloud generation and cleaning of raw LiDAR data acquired by the HawkEye and Chiroptera systems.
It provides an extensive software toolbox for processing of multiple missions and simultaneous review of data from all sensor channels. This allows review of the deep bathymetry, the shallow and the topographic LiDAR data, which at the same time including reviewing the image taken at the same location as the point cloud data.
Together, HawkEye III, Chiroptera and LiDAR Survey Studio represent the next generation of state-of-the-art airborne bathymetry.
