How accurate is drone mapping in construction?
Surveying drone solutions can produce different degrees of accuracy, depending on the requirements of the project.
In an independent study by DroneDeploy, the DJI Phantom 4 RTK achieved 2cm relative vertical accuracy and 1.20cm relative horizontal accuracy.
An accuracy report with heliguy™ client Terra Drone Europe also showed that the DJI Phantom 4 RTK can achieve 3cm-4cm accuracies without needing to lay any ground control points.
