Introduction of the current research team in the newest volume of "Kennis voor Klimaat - Decision Support Tools", page 7
The aim of this project is to make fast and effective simulation and visualization tools for integrated water management policy development and planning. Within this project, the results of the investigation can be evaluated on the basis of practical problems, and usability of the tools can be examined.
As a first result of this project, a prototype software system has been developed for interactive 3D visualization of very large 3D geographic data sets. Raw laser scan data and photographs from the new "Actual Height Database of the Netherlands" (AHN2) are used, in which both the landscape and structures such as vegetation and buildings are included in great detail. Without the need for manual 3D modelling, the visualization shows a realistic and complete picture of the landscape in 3D. The specific data and software structure can guarantee a smooth image on the screen, which allows interactive navigation through the 3D landscape. An initial integration with numerical flooding models such as Sobek produces 3D images of static water levels, e.g. due to extreme rainfall.
The software system is suitable for large-screen stereo projection for increased the visual impact and spatial insight. Also, a mobile stereo projection setup was built for demonstrations and case studies. The first results of static flooding scenarios have been frequently demonstrated, including the "Deltas in Times of Climate Change" conference held in Rotterdam. Also, a first evaluation of the system and visualization was performed in an emergency exercise with the Waterboard of Delfland, the City of Delft, and local emergency services, in November 2010.
The context of our work is a combination of two projects: First, the scientific program is Knowledge For Climate (Kennis voor Klimaat (KvK)), and within this we work in Theme 8: Tools for Adaptation Strategies,Workpackage 4: Visualization and simulation of impacts and strategies, and project 4.3: Interactive simulation and 3D visualization for water protection policy development. Second, more practical concerns and cases are performed in the context of the 3Di Water management project.
