Paper Abstract

Digital Earth (DE) is a virtual presentation of the planet based on geographic coordinate, and is an information system with tremendous amount of multiple resolutions and multiple scales data as shown in multiple dimensions. Since the exact description about DE has not completed, most experts have their own understanding of DE, so there are a lot of various digital earth prototype system was developed, such as the Alexandria digital earth modeling system developed by the UCSB, digital earth prototype developed by the NASA, and earth simulator developed by the Japan and so on. Each of them has their own infrastructure and characteristics in developing process. Besides, there are still many commercial digital earth software popularly, such as the famous Google earth, word wind, skyline, and blue link and so on. They have the one biggest common that is all of them were based on the vast remote sensing image and represented by virtual reality technology. But when we reviewed the current situation of digital earth research presented from the outcomes of the International Symposium on Digital Earth four times, and investigated most of these digital earth system and software, we found the studies on digital earth system have some shortcomings. Therefore, facing this situation, in this paper, firstly, we will review the situation and the development of the Digital Earth research. Then, we will emphasize on how to construct the Digital Earth Prototype and develop its system from some new perspectives by the most prevalent techniques.
