摘要
Over the past years,a wide spectrum of disciplines covering geoscience,space science and information science and technology have made rapid progress with great social and economic benefits.With the advances of these digital techniques and their broad applications in the very fabric of modern life and society,the demand has been raised for combining and distributing this information about these enormous and dynamic,multi-resolution and three dimension description data sets.Digital earth is the ideal way to integrate,utilize and share data and information resources,the principal part of information resources in achieving sustainable development,and the important area to develop global service.It can be expected that the raised emphasis and pursuit of global technology groups,enterprise groups and government groups on digital earth must result in the predominant development in human being’s history as digital earth.
