Digital Earth [1] refers to the concept proposed by former US vice president Al Gore in 1998, which is described as a virtual representation of the Earth that is spatially referenced and interconnected with the world's digital knowledge archives. Digital Earth promises to make the unified representative and recognition about the real earth and related phenomenon. Specifically it based on computing technology, multimedia technology and large-scale storage technology, interconnected with broadband network, the use of vast amount geo-referenced information to present earth in three-dimensional description of multi-resolution, multi-scale, multi-dimensional and multi-species, the use of information technology to process the entire planet's natural and social activities of various aspects, maximize the use of geo-information resources, and take it as a tool to transform nature and society, to promote the development of human civilization. Digital Earth is considered to be the best way of integrated use of shared data and information resources available, and the main and core body in the process of sustainable development with information resource. Digital Earth will play important role in

Digital Earth has raised the attention of governments, around support for "Digital Earth" concept and the development of key technologies, and set off a new round of information technology infrastructure and applications development boom on a global scale. Increasingly it has formed a lot of strategic directions, such as Digital China, Digital Government, Digital City, Digital Transportation, Digital Agriculture, Digital Meteorology, etc. National information infrastructure, national spatial data infrastructure and a large number of high-tech project started, and Digital Earth related computing science, large-scale storage, high-resolution satellite images, broadband network, spatial information technology, interoperability and metadata, visualization, and virtual reality, etc. technologies achieved breakthrough progress, and shown great potential for innovation.

With the concept of Digital Earth and Digital China in-depth development and popularization, continue to promote the theory and technology, accelerating the pace of project construction, the concept of Digital Railway gradually formed in the railway
