How accurate is a drone survey?

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.

For some applications, like checking crop growth, or construction progress, high relative accuracy is sufficient. For other jobs that also require high absolute accuracy, there are drones equipped with Real-Time Kinematic (RTK) and Post-Processed Kinematic (PPK) capabilities. When paired with a few Ground Control Points, survey-level accuracy can be achieved.
