A good understanding of the principles of LiDAR scanning will enable you to obtain high quality LiDAR scans.
The parameters governing LiDAR scanning are described below
The concept of frequency setting is illustrated below
Point density is a function of the following parameters
The figures below show the relationship of point density to the frequency setting, platform speed and flight altitude (AGL)
Statistical Deviation from GCP’s
Actual accuracy is dependent on GPS processing options (RTK, PPK, WAAS), ionospheric conditions, satellite visibility, flight altitude (AGL) and other factors
The Cross Profile Shows a Standard Deviation of < 5cm in Altitude
