We're adding drone mapping. How do we tie it into our total station and GNSS work?

Treat drone data as one more dataset that needs control and checks [1]:

  • Ground control points measured with GNSS or a total station, spread across the site and at different elevations.
  • Independent checkpoints, not used in processing, to report real accuracy [1].
  • The same datum and units as the conventional survey.
  • Know its limits: vegetation, steep faces and hard edges such as curbs often need conventional shots.
  • Merge thoughtfully: combine drone surfaces with field-surveyed breaklines and features.
  • Document: accuracy statements, processing reports and which areas came from which method.

Drones are excellent for volumes, open-site topography and imagery. For boundary evidence and precise hardscape, keep conventional methods in the mix [2].
