TOPODRONE Launches AQUAMAPPER Airborne Bathymetric Surveying Resolution

by DRONELIFE Employees Author Ian M. Crosby

At international mapping present INTERGEO this week, LiDAR gear firm TOPODRONE has launched AQUAMAPPER, a UAV-based resolution for bathymetric surveying and marine development.  Bathymetric surveying is the underwater equal of topographic surveying, mapping the ground of rivers, lakes and oceans.  The brand new multitasking information accumulating machine has been efficiently deployed alongside TOPODRONE LiDAR ULTRA gear for the airborne surveying of a Romanian freeway development undertaking in an effort to present a digital twin of a scanned space.

The brand new AQUAMAPPER {hardware} integrates with different expertise to kind a complete set of photogrammetry, LiDAR and bathymetry surveying options. Upon being mounted to a UAV, AQUAMAPPER presents excessive pace effectivity (as much as 14 km/h) and accuracy. The PPK prepared resolution can be suitable with DJI Matrice 300 RTK. The {hardware} will be deployed for a variety of use instances, together with an open sea bathymetric survey as much as 100m depth, amount survey and calculation of sediments, and periodic upkeep survey of storage swimming pools.

TOPODRONE AQUAMAPPER and LiDAR ULTRA have been deployed in an airborne surveying mission at “Autostrada Sibiu – Pitești, Secțiunea 2: Boița – Cornetu”, a European highway development undertaking. The undertaking seeks to assemble a freeway in one in every of Romania’s most rugged environments, and incorporates 7 tunnels, 24 bridges and 18 viaducts. The drone LiDAR hall and bathymetric survey was performed by Romanian firm GRAPHEIN TOPO SA in an effort to produce correct maps and present data relating to terrain stage, buildings, roads, energy line networks, cadastral boundaries, and rivers. TOPODRPONE’s LiDAR ULTRA was deployed on board a DJI M300 drone, and was utilized to gather laser scanning information from 100 – 120 meters above the forested terrain, overlaying a 32 km lengthy and 400 meters vast hall over the course of 14 flights. On the identical time, AQUAMAPPER {hardware} connected to the identical drone performed a bathymetry survey over 6 river crossings.

“The important thing benefit of the brand new bathymetric gear from TOPODRONE is the power to seize a riverbed with centimeters stage accuracy with excessive pace in absolutely computerized mode and with out utilizing any boat. It permits us to work in laborious to entry and shallow water areas,” stated Andrei Sueran, GRAPHEIN TOPO SA. “The identical drone service can be utilized for each LiDAR & bathymetry surveys. The mixture of an echosounder, GNSS and Inertial measurement system helps to get correct outcomes after information submit processing.”
