As the recognized industry leader in the development and application of bathymetry LiDAR technology, Fugro provides the world’s most operationally reliable and cost-effective ALB survey services.
How does it work
Airborne LiDAR bathymetry systems work by transmitting pulses of energy from a laser source. Infrared energy is quickly absorbed thereby detecting the water surface, while energy in the green spectral band penetrates into the water to map the surface of the seafloor. The delta of the water surface and seafloor measurements provides the water depth. Depending on water clarity, seabed characteristics, and energy output, airborne LiDAR bathymetry is effective in water depths up to 70 meters.
Benefits
- Accurate depth measurement
- Very cost effective over full operational window
- Speed
- Mobility
- Rapid response
- Rapid data assessment: storm damage, grounding, seasonal change
- Completion of surveys in small environmental windows
- Survey difficult or impossible areas
- Safe in dangerous areas
- Simultaneously survey water, structures, and land
- Operates in shallow water regions
- Extends survey over the beach
- Rapid response to new survey areas
- Complimentary with Sonar systems
- The shallow coastal zone is particularly difficult to survey
Applications of the technology:
-
Nautical charting particularly of shallow, remote and hazardous areas
- Survey support to survey vessels
- Coastal zone management, particularly surveys close inshore, including beach surveys
- Rivers, Lakes and Inland Waterways
- Essential Fish Habitat Mapping
- Coral Reef Mapping, in particular for nautical charting or environmental management
- LOS / EEZ Mapping
- Pre-Post Hurricane Mapping
- Support to oil and gas industry, including data to support seismic vessel navigation, planning of pipeline landfalls and surveys for infrastructure planning and development and general operations
- Defense applications
- Pipeline surveys and landing points
- Combine with MBES for optimal efficiency and safety
