Ven-Tech Subsea proudly offers cutting-edge UAV bathymetric LiDAR mapping services, delivering high resolution, accurate, and efficient survey data for coastal, marine, and inland waterway applications. Our aerial LiDAR system captures detailed seafloor and submerged topography data with the precision and speed required for engineering, environmental, and infrastructure projects.
Green Laser Bathymetry: Can penetrate water and map submerged terrain continuously, delivering both above-water topography and underwater bathymetry in one pass.
High Precision & Accuracy: 3 cm precision (≈1.2 in), with similar accuracy; field-tested performance ensures reliable results for engineering and survey grade needs.
Extended Flight Autonomy: Up to ~45 minutes of flight time per battery, enabling large area coverage with fewer takeoffs/landings.
High Shot Density & Rapid Scanning: Up to 20,000 shots per second, scanning at ~50 Hz; multiple echoes (up to 10 per shot); 40° field of view.
Multi-Platform Compatibility: Designed for drones (multirotor or helicopter UAVs) via quick-release adapters; lightweight (~3.7 kg excluding battery) to support versatility
Our bathymetric UAV LiDAR service is perfect for:
Coastal & Shoreline Mapping — monitoring erosion, mapping intertidal zones, beach replenishment projects.
River, Lake & Reservoir Surveys — measuring depth, sediment buildup, shoals, and hydraulic structure condition.
Submerged Structure Inspections — dams, intakes, water treatment infrastructure.
Dredging & Marine Works — pre/during/post dredging bathymetric profiles, scour detection.
Environmental & Habitat Studies — mapping aquatic vegetation, benthic habitats, underwater archaeology.
Floodplain & Hydraulic Modeling — acquiring data in shallow water areas where boat surveys are costly or difficult.

Bathymetric LiDAR & UAV Seafloor Mapping Services
Safety and regulatory adherence are foundational to our operation:
-Fully certified pilots/operators (UAV regulatory compliance) and mapped with safety planning for water operations
-Operate in daylight, favorable weather and water clarity (typically water clarity up to ~2 Secchi depths for effective penetration)
-Laser classification and safety protocols in place (Class 3B laser systems, ocular hazard zone considered)
-Environmental protection: minimal disturbance, no waterborne vessels required for many surveys.
