Geo-MMS LiDAR Mapping Principles

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) 


 

Flight Configuration

Flight Coverage

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
