摘要
空间数据集成是解决异构网络环境信息系统间空间数据交换、传输和共享、数据互操作的有效方法。笔者在分析生态环境数据特征和生成机理以及集成原理基础上 ,提出了生态环境空间数据的空间多尺度集成方法 ,并构建了基于面向应用目标的生态环境空间数据集成系统框架和运行过程机制。
Spatial integration is a powerful approach to spatial data exchange,transformation,data sharing,and interoperability between network based heterogeneous environmental information systems.Multi scale spatial data integration methods,associated with eco environmental spatial data,were characterized based on the identification of characteristic of eco environmental spatial data and integration mechanism.An application oriented integration architecture of eco environmental spatial data was presented.In addition,operational procedure of integration was also outlined.
