Use of accurate digital surface models generated from digital aerial photogrammetry for urban flood modelling

Due to climate change and an expansion of urban catchment, urban flooding is becoming a major environmental hazard and can cause very costly damages to properties and assets around Australia. The insurance industry is in real need of accurate information for their use in risk analysis and urban flood vulnerability.

 

Innovation and technologic improvement in the acquisition technics and the processing of digital elevation models can make it economically feasible to gather large and accurate 3D information of natural and urban areas.
