Common Questions About Drone Surveys - Bathymetric
Everything you need to know about our managed bathymetric survey service
Modern drone bathymetric systems achieve depth accuracy of less than 2cm using RTK GPS positioning and calibrated echo sounders. Dual-frequency sonar ensures reliable readings across various water conditions.
Echo sounder systems can measure depths up to 200 meters. Bathymetric <Link href="https://hiredronepilot.uk/services/drone-lidar-mapping" className="text-orange-600 hover:text-orange-700 underline">LiDAR</Link> is most effective in shallow waters up to 10-15 meters depending on water clarity.
Echo sounders work effectively in all water clarities. LiDAR performance depends on water transparency, but sonar-based systems are unaffected by turbidity.
Deliverables include 3D point clouds, contour maps, cross-sections, volumetric calculations, and GIS-compatible formats (DXF, DWG, SHP, XYZ).
Dual-frequency <Link href="https://hiredronepilot.uk/services/drone-sonar-survey" className="text-orange-600 hover:text-orange-700 underline">sonar</Link> differentiates between vegetation and solid bottom. We provide both surface and sub-vegetation depth measurements for comprehensive analysis.
Yes. We merge bathymetric data with <Link href="https://hiredronepilot.uk/services/drone-photogrammetry-survey" className="text-orange-600 hover:text-orange-700 underline">aerial photogrammetry</Link> to create seamless above and below water 3D models in a single dataset.
