Abstract
Recently, the technology of 3D-GIS (Geography Information System) has developed. And, three-dimensional modeling of the city structure had proceeded rapidly. Furthermore, it became possible that a three-dimensional space can be analyzed by the combination with the attribute information of the three-dimensional model. And, it is easy to express the result of the analysis.
In this research, we studied about an electric wave route for satellite simulation system based on the development of 3D-GIS technology. Then, we must consider electric wave route being blocked by structures. Moreover, we verified the result of this system.
