English abstract:
The last decade has seen an increasing demand for high-resolution and
high-accuracy digital terrain and surface model data in various
Airborne Laser Scanning (ALS) is a suitable technique for acquiring
spatial data with a high point density. Commercial ALS systems could
deliver only the first and last echo of a laser beam. However, this is not
for many applications, especially in areas with dense canopy cover or high
housing density.
The newest generation of scanners, recording the full waveform of the
reflected laser pulse, make a high density data acquisition possible in
this type of regions. For echo detection and quantification, a
sophisticated signal analysis is required which is being developed and not
yet standardized. In this paper, the principle of full-waveform (FWF) ALS,
methods of data processing and some application examples are presented.
The range of applications includes flood control measures and
environmental monitoring as well as archaeology and tectonic
