How accurate is LiDAR?
LiDAR is one of the most accurate surveying technologies.
To help achieve accuracy on airborne laser sensors, they are paired with IMU (inertial motion unit) and a GNSS receiver. This helps to achieve a high relative accuracy of 1-3cm. With the addition of ground control points (GCPs), higher absolute accuracies can be achieved.
If additional GNSS positioning accuracy is needed, PPK and RTK can be used.
