Zusammenfassung |
Estimating flood risks and managing disasters combines knowledge in
climatology, meteorology, hydrology, hydraulic engineering, statistics,
planning and geography – thus a complex multi-faceted problem. This study
focuses on the capabilities of multi-source remote sensing data to support
decision-making before, during and after a flood event. With our focus on
urbanized areas, sample methods and applications show multi-scale products
from the hazard and vulnerability perspective of the risk framework. From
the hazard side, we present capabilities with which to assess flood-prone areas before an
expected disaster. Then we map the spatial impact during or after a flood and
finally, we analyze damage grades after a flood disaster. From the
vulnerability side, we monitor urbanization over time on an urban footprint
level, classify urban structures on an individual building level, assess
building stability and quantify probably affected people. The results show a
large database for sustainable development and for developing mitigation
strategies, ad-hoc coordination of relief measures and organizing
rehabilitation. |
