数字地球中海量信息汇聚调度的应用实现

构建数字地球需要融合海量地理信息、高程信息、航拍信息、标注信息和其他用户自定义业务信息。如何汇聚调度这些海量数据是实现数字地球软件平台的关键问题。针对这一问题，本文分析了数字地球平台的信息汇聚实施网络拓扑结构、信息处理软件架构，研究信息分类调用与汇聚模块设计及全球海量影像数据的调度策略。基于上述研究成果，初步在项目中实现数字地球平台。

Application and implementation of massive information aggregation scheduler in Digital earth

Constructing digital earth needs to fusion mass geographic information, elevation information, aerial information, label information and other user-defined business information. How to aggregation scheduler these massive data is the key problem to realize the digital earth platform. Aiming at this problem, this paper analyzes network topology implementation information processing software architecture of the digital earth platform for information gathering, researches information classify calls, convergence module design and the global mass image data scheduling strategy. Based on the results above, in the project realized the digital earth platform initially.
