| Zusammenfassung |
| Digital terrain models form the basis for distributed hydrologic models as
well as for two-dimensional hydraulic river flood models. The technique used
for generating high accuracy digital terrain models has shifted from
stereoscopic aerial-photography to airborne laser scanning during the last
years. Since the disastrous floods 2002 in Austria, large airborne
laser-scanning flight campaigns have been carried out for several river
basins. Additionally to the topographic information, laser scanner data
offer also the possibility to estimate object heights (vegetation,
buildings). Detailed land cover maps can be derived in conjunction with the
complementary information provided by high-resolution colour-infrared
orthophotos. As already shown in several studies, the potential of airborne
laser scanning to provide data for hydrologic/hydraulic applications is
high. These studies were mostly constraint to small test sites. To overcome
this spatial limitation, the current paper summarises the experiences to
process airborne laser scanner data for large mountainous regions, thereby
demonstrating the applicability of this technique in real-world hydrological
applications. |
