以信息的获取、处理和应用为主线,把"数字地球"技术系统分为数据获取与更新子系统、数据处理与存储子系统、数据与信息传播子系统、应用子系统(应用模型库)、标准化和其它相关子系统,并讨论了每个子系统的信息基础设施和核心支撑技术.
In the whole process of acquiring, disposing and applying information, the 'Digital Earth' technical system is divided into several subsystems such as data acquiring and refreshing subsystem, data disposing and memorizing subsystem, data and information transferring subsystem, application subsystem (application model base), standards and other related subsystems.
