Topo-bathymetry services

Once again thanks to our R&D at Datadron, we have developed a new technology which allows to correct for refraction error caused by the air/water interface while using photogrammetry and producing point clouds which include a submersed portion of the survey.

We have developed a full workflow which comprehends from that data acquisition phase to the data processing and final refraction error correction induced by the water column. We must say that this technology only works if the water is clear enough to see the seabed and the environmental conditions are calm enough. But if requirements are fullfill then we have managed to penetrate down to 8 – 10 m with an averaged error of less than 10 cm.
