3D and dynamic visualization of green space

Visualization (2D photomontages, 3D virtual reality, viewpoint & walk-through visualizations) have been used by the Scottish, Swiss and Spanish teams as a communication tool to provide information to support the survey and focus groups approaches to eliciting people's true preference for green space attributes. In addition, visualization was applied by the Zurich team as a direct research tool to investigate people�s reaction to issues such as enclosure/safety, management intensity and the inclusion of wind turbines. The application of visualization for green space research is demanding given that it has been combined with GIS and must represent detailed soft features (i.e. vegetation). However, where communication is the goal, results can be achieved with less sophisticated static 3D images.

Thus visualization has been a useful research and communicative tool. The urban parks studied offer the prospect of a greater understanding of human behaviour. It is important to ensure that as reactions to visualization derive from the critical psychological domain and not simply from an aesthetic one. Thus the main substance of the virtual images is not the aesthetic, but instead the capacity to open a discussion or to transmit a message.

From the consideration that knowledge is based on experience, the presentation of a virtual park, can transform an "authentic" experience into an interpretation of multiple and different contexts. The use of information and communication technology not only plays an important role for the representation and for the analysis of urban parks, but also provides potential for the active involvement of citizens in the decision making and in the management of the urban parks.
