Visualization as Element of Decision- and Action-Space

The process of rationalizing decisions by visualization in different qualities is outlined. 3D-visualization is – not yet – the standard instrument to work with, such as the 2D-planning of the development of cities. For the planning and development of a new part of the city “Hennef ” in Germany, the concept of a long-term study on 10 years is defined. The methodology uses a standard geoinformation system as an online-tool to visualize in three dimensions the discussions on the future design during the session in the city hall. Both the simple procedure of block-modelling and the resulting final product in animated 3D-visualizations are presented, technical support is discussed and the resulting benefit is previewed
