What is a Bathymetric LiDAR?

Bathymetric Lidar, or bathymetric Light Detection and Ranging, is a technology used for measuring underwater topography and mapping the depth of water bodies. Lidar systems typically involve sending laser pulses from an airborne or terrestrial platform and measuring the time it takes for the light to return after hitting the Earth's surface. Bathymetric Lidar specifically focuses on the mapping of underwater features, making it a valuable tool for coastal zone mapping, hydrographic surveying, and marine applications.

Here's how Bathymetric Lidar generally works:

  1. Laser Emission: A laser emits pulses of light towards the water surface.

  2. Surface Interaction: The laser pulses penetrate the water and interact with the seafloor or underwater features.

  3. Return Signals: The reflected light (backscattered signal) is detected by the Lidar sensor.

  4. Data Processing: The time taken for the laser pulses to travel to the seafloor and back is used to calculate the depth of the water at different points.

Embark on a revolutionary journey with the YellowScan Navigator, an innovative bathymetric LiDAR solution designed for unmanned aerial vehicles (UAVs). This state-of-the-art technology redefines mapping capabilities by effortlessly capturing water surfaces and underwater topography with a single-button operation. The Navigator's compact design ensures versatility across various UAV platforms without compromising its ability to penetrate water effectively. Explore shorelines, rivers, and ponds with unparalleled ease, obtaining simultaneous land and underwater topography for comprehensive surveying. Welcome to a new era of precision mapping with YellowScan Navigator.

Diverse Water Environments

Intended for aerial use on drones, the system covers various water areas such as shorelines, rivers, lakes, estuaries, ponds and gravel pits. Navigator is user-friendly and adaptable for a wide range of applications, from hydrographic surveys to underwater resource management.

44° FOV for High Precision

Our bathymetric system, with a 44-degree field of view, prioritizes precision over a broader angle. This decision is based on the fact that 44° is the maximum angle for a green laser to perform effectively underwater. Beyond this angle, the laser’s penetration depth in water is significantly affected, limiting the system’s overall performance.
