"Potential of Terrestrial and Airborne LiDAR in Geomorphology - A Geomorphological Perspective";
Poster: EGU 2009, Vienna; 2009-04-19 - 2009-04-24; in: "Geophysical Research Abstracts", 11 (2009), Paper ID EGU2009-6188, 1 pages.

The number of studies using Terrestrial or Airborne LiDAR, also referred to as laser scanning, in geomorphology
is significantly increasing. Both techniques can deliver high resolution digital terrain models (DTM) or digital
surface models (DSM) but on different scales. Whereas resolution and accuracy for Airborne LiDAR are currently
in the submeter range, respective values for Terrestrial LiDAR are at centimeter scale. Especially, the high
resolution DTM provides a sound basis for geomorphological mapping, process modeling and subsequently for
hazard assessments. Multitemporal laser scanning can significantly improve the monitoring of geomorphological
processes.
Applications of the LiDAR techniques are available in all geomorphological fields (e.g. for studying glacial,
periglacial, fluvial and aeolian processes, landslides and soil erosion). A review is given on the use of Terrestrial
and Airborne LiDAR in geomorphology based on common technologies. Since LiDAR technology is progressing
and new techniques and data is already available (e.g. full-waveform LiDAR systems) and are expected to become
operational in the near future, geomorphological perspectives resulting from these technological developments are
addressed.
Furthermore, beside the potential of Terrestrial and Airborne LiDAR, the specific limitations are discussed as well
as the benefits which arise when both techniques are combined.
