摘要
综合数字地球平台优势的空间分析功能是空间信息应用领域内的新需求,也是数字地球平台向专业级应用发展中必须解决好的重要问题。研究针对空间信息数据海量、异构、分布性等特征,结合实际应用中综合多样化数据源、跨平台数据共享的需求,提出了一种基于多源数据聚合机制的空间分析功能模块的设计思路和实现方法,同时提出了一套适用于跨平台分析结果共享的描述语言规范和共享机制,一定程度上填补了现有数字地球平台上空间分析功能的不足,为数字地球平台专业化应用做出了探索与尝试。研究在提出理论架构的基础上,依照设计思路实现了部分基础分析功能,并在实践中验证了其可行性与优越性。
The spatial analysis function with the digital earth platform advantages is the new demands of spatial information applications; it is also the problem which must be solved in the development process of professional-level application of digital earth platform. These research is considered the characteristics of the data in the massive, heterogeneous and distributed, and cater to the actual application requirements of diverse data sources and cross-platform data sharing. Then it puts forward the design and realization methods of the spatial analysis module, which is based on the multi-source data aggregation mechanism. It also proposes a set of markup language standard and sharing mechanism applied to cross-platform sharing of the results of the analysis. It fills the lack of existing digital earth platform on the spatial analysis functions, and contributes to the professional-level application of digital earth platform. This study has achieved a part of the basic analysis functions based on the theoretical framework, then to verify its feasibility and superiority in practice.
