"Progress in LiDAR sensor technology - chance and challenge for DTM generation and data administration";
Talk: Photogrammetric Week, Suttgart (invited); 2007-09-03 - 2007-09-07; in: "Proceedings of the 51th Photogrammetric Week", D. Fritsch (ed.); Herbert Wichmann Verlag, (2007), ISBN: 978-3-87907-452-5; 159 - 169.

Airborne laser scanning - also referred to as LIDAR - became a standard method for the acquisition of topographic data.
However, since the first commercial flights in 1994 a significant development in the sensor technology can be observed.
These developments lead to a high increase in data volume due to a significant higher number of determined echoes as
well as due to an increased number of information stored per echo.
Next to a short presentation of the current sensor developments this paper focuses on the current challenges in
management of ALS data including the storage of additional information provided by full-waveform ALS sensors.
Furthermore, advanced procedures for DTM generation integrating geometric criteria with these additional attributes
per echo are discussed.
