Drone surveying and 3D scanning of sites and buildings

A drone is a tool that can make a surveyor's job easier. On a large site it can be faster, while for a small plot a conventional survey is often more practical.

Which method to choose

Task Method Result
Plot of up to a few thousand m² Conventional (GNSS, total station) Site plan / topographic plan
Large or hard-to-reach land Drone (photogrammetry) Orthophoto, digital terrain model, contour lines
Volumes: quarry, landfill, excavation Drone Volume calculations
Façades, interiors, reconstruction 3D laser scanning Point cloud, 3D model, 2D drawings
Cadastral boundaries Conventional + on-site checks Accurate boundary points
A drone surveying the site; alongside, an orthophoto and a 3D terrain model

What to watch out for

  • In cadastral procedures a drone is an auxiliary tool; boundaries are confirmed by measurement on the ground.
  • Drone flying is subject to rules and no-fly zones (airports, military sites). Complying with them is the contractor's responsibility.
  • Before hiring, check the required accuracy and whether ground control points are planned.
