The total drone surveying workflow
Creating a topographic survey with a drone is a completely different process compared to a terrestrial survey with the boots on the ground.
A topographic surveyor models the outside world by measuring as few points and lines as possible, while surveying with a drone requires flightplanning, piloting, an entire logistic operation and photogrammetry.
Another big challenge is that the orthophotos, elevation models and point clouds coming out from the photogrammetry process differ completely from what the engineers expect the surveyor to deliver. Civil or mine engineers want a lightweight but meaningful CAD model that they can load directly in their CAD design software packages.
Drone mapping at kardia mine
The Kardia mine in West Macedonia saves big bucks with more accurate volume measurements using drone surveying. The surveying team operates the following workflow on a monthly basis:
- Flight planning with eMotion software.
- Drone flight with the eBee RTK from SenseFly.
- Photogrammetry with Pix4Dmapper software.
- Removal of conveyors, measurement of volumes and drawing of breaklines with Virtual Surveyor software.
- Constructing future excavations with Anadelta Tessera software.
