In this overview paper the principles of laser scanning systems are presented.This includes a survey of different range measurement principles as well as differentmechanisms for the deflection of the emitted laser beam. Furthermore, the usage of thelaser scanning (LS) principle at different platforms (airborne (ALS), terrestrial (TLS),satellite) is discussed. Additionally, typical sensor parameters of currently commerciallyavailable sensor systems are presented. Furthermore, the technique of full-waveform LSis introduced and georeferencing of ALS data for improved precision is presented. Theusage of LS data in different applications will be presented in an overview.
