Integration of Digital Earth and physics engine for spatial simulation

The spatial simulation such as one of the landslide may play an important part for research, decision-making or forecast of spatial variation. Digital Earth (DE) can be become a very useful platform for the spatial simulation. Google Earth, very successful use case for DE, is very useful platform for visualizing geo-referenced data, but limited for the spatial simulation. In the paper, a method for integration of DE and a physics engine was proposed. The proposed method simulates a spatial change by the local physics engine and combines the simulation result with images of DE on online. The paper presents simple landslide simulation by the simple integration software, implemented by the proposed method.
