Leica Lidar Sensor Improves Bathymetry
The new Leica Chiroptera-5 is a high-performance airborne bathymetric lidar sensor for coastal and inland water surveys.
Offered by Leica Geosystems, Chiroptera-5 provides 40% higher point density, a 20% increase in water-depth penetration, and improved topographic sensitivity for generating more detailed hydrographic maps.
The technology increases the depth penetration, point density and topographic sensitivity of the sensor compared to previous generations. It delivers high-resolution lidar data supporting applications such as nautical charting, coastal infrastructure planning, environmental monitoring and landslide and erosion risk assessments.
Chiroptera-5 combines airborne bathymetric and topographic lidar sensors with a four-band camera to collect seamless data from the seabed to land. With a higher pulse repetition frequency (PRF), the new technology increases point density by 40% compared to the previous generation system, collecting more data during every survey flight.
Improved electronics and optics increase water-depth penetration by 20% and double the hydrographic sensitivity to capture larger areas of submerged terrain and objects with greater detail. The high-performance sensor is designed to fit a stabilizing mount, enabling more efficient area coverage, which decreases the operational costs and carbon footprint of mapping projects.
