Abstract
In this study, we made a landscape visualization system that enables virtual experience in a planned landscape including vegetation on Google Earth. The applicability of the system to the landscape design was quite powerful. The planning system generates KML (Keyhole Markup Language) and VRML. KML file is visualized on Google Earth and VRML file can be visualized on stand alone computer. Plants were automatically placed on a terrain based on the data of GIS or Excel by using the system developed in this study. With the system, we made models of Koishikawa Korakuen Garden based on measured data. Performance of walk-through simulations was quite good. We proved that landscape visualization and simulation with Google Earth was possible and that the system can be used as a practical and low cost landscape simulation tool.
Highlights
Google Earth is broadly used by seeing the aerial view and it is used to show the three dimensional scenery
Because many realistic architectures are placed on city area, virtual experience of walking through streets is possible in some area in the big cities But there are few vegetation models on the Google Earth and it is difficult to experience walk-through in parks
By using the developed landscape visualization system, a KML program was made from collected data and the performance of the system was evaluated
Summary
Google Earth is broadly used by seeing the aerial view and it is used to show the three dimensional scenery. Because many realistic architectures are placed on city area, virtual experience of walking through streets is possible in some area in the big cities But there are few vegetation models on the Google Earth and it is difficult to experience walk-through in parks. We have been studying the walk-through simulation in the landscape with the system that used VRML (Virtual Reality Modeling Language) (Honjo and Lim [3], Lim and Honjo [4], Lim et al.[5]). Visualization on Google Earth, which uses KML (Keyhole Markup Language), is achieved with same method in the system of VRML. By using Google Earth or VRML, walk-through simulation is made possible. We used this modeling technique of plants for the visualization of forests and parks
