How Bathymetric LIDAR Surveys Are Done Using Key Technology for Accurate Depth Mapping

Pinpointing the perfect underwater landscape starts with the right tools and technology. Bathymetric LIDAR surveys are essential for understanding underwater terrain and are commonly used in industries like marine construction, environmental monitoring, oil and gas exploration, and now, floating solar. Lidar’s high-precision data collection has revolutionized these surveys, making it the go-to solution for identifying optimal locations for floating solar anchoring and installation.

What is LiDAR?

LiDAR technology functions like a high-tech tape measure. It emits thousands of laser pulses per second, which bounce off objects and return to the sensor. By measuring the time it takes for each pulse to travel to the object and back, LiDAR determines precise distances. This process creates highly detailed and accurate depth maps of the Earth’s surface. LiDAR systems are often mounted on aerial platforms such as drones, helicopters, or airplanes. This allows for large-scale surveys to be conducted much faster than traditional methods.

One of the standout advantages of bathymetric LiDAR surveys is their ability to collect data in shallow and complex areas. Even in turbid or murky water, LiDAR produces clear, precise data. These surveys are less intrusive, minimizing disturbance to marine life and ecosystems. By combining lidar data with GPS and inertial measurement units (IMUs), surveyors achieve unparalleled accuracy in depth measurements, regardless of the water environment.

LiDAR and Floating Solar Arrays

Floating solar installations depend on accurate water depth data to ensure secure anchoring and long-term stability. Bathymetric surveys using key LiDAR technology provide precise depth measurements and detailed maps of underwater terrain, enabling developers to identify the most suitable anchoring locations. These surveys reveal critical variations in depth and highlight potential obstacles that could affect the structural integrity of floating arrays. By capturing data in shallow or intricate water environments where traditional methods may fall short, LiDAR ensures every anchor point is optimized for stability and resilience. This precise depth mapping minimizes installation risks and ensures floating solar arrays are securely positioned for peak performance. At AccuSolar, we use Helioscope, which offers site-specific insights, allowing us to assess a site thoroughly without the need for a physical visit.

Once the data is collected, it undergoes post-processing to create detailed 3D maps and models. This step involves filtering out noise caused by water turbidity, ensuring only high-quality data is used. Advanced software tools enable surveyors to analyze the data for various applications, from identifying underwater hazards to monitoring changes in sediment patterns. The end result is a clearer understanding of the underwater environment, which is essential for both floating solar installation and environmental monitoring.

LIDAR Bathymetry and LIDAR Technology: The Future

Bathymetric LiDAR technology has transformed the way we approach underwater mapping. It offers an innovative and efficient solution for floating solar projects. By providing accurate depth measurements and high-quality terrain data, LiDAR ensures secure and optimal installation of floating solar arrays. This technology enhances the stability of these systems. It also minimizes environmental impact, making it an invaluable tool in renewable energy development. Lidar bathymetry, with its ability to capture precise underwater data, contributes to the efficiency and success of floating solar installations.
