Applying DTMs derived from laser scanner data yields major advantages for modeling flood risk areas. To meet the exceptionally high accuracy requirements as stated by hydrologists, careful application of advanced DTM technology is inevitable. Below, the following points are addressed:
. Geo-referencing airborne laser scanner data,
. Interpolation of DTMs taking into consideration break line information - semiautomatically extracted from the laser scanner data by means of mathematical snake curves,
. Deriving models of buildings and of vegetation models - to serve in taking into consideration surface roughness influencing the runoff of the water,
. Elevation accuracy of laser scanner DTMs, and position accuracy of the border of the flooded area as predicted for floods,
. Supporting documents for flood management.
