Today our #3DMonday feature takes us to a drone-based resources management project in Canberra, Australia:Sketchfab link
The project in the words of its creator:
“4D Surveying was asked to be the auditing surveyor for the quarterly volumes of the new zone cell 1 on site. As part of that survey, I was requested to do an overall flight of the whole tip site which I 3D modeled in Pix4Dmapper. 28 GCP’s were placed, 866 images calibrated (100%) with an RMS of 0.021m. This data will be used as a benchmark for further flights to be compared against.
Building on my Land Surveyor skills and experience, I specialise in Drone Surveying for large-scale mapping. I got a Pix4Dmapper with my purchase of the eBee from Sensefly and I love its ease of use and haven’t needed to try anything else.” Peter Williams, Managing Director at 4D Surveying.
