一种支持数据发现及服务集成的遥感影像元数据模型设计

A RS Image Metadata Model Design Supporting Data Search and Service Integration

针对数据共享模式发展的要求,在分析遥感影像元数据模型研究现状的基础上,将传统静态的数据集元数据与动态的数据服务元数据相结合,提出了一种适用于计算机动态发现数据并集成数据服务的遥感影像元数据模型。基于该模型进行了"Machine to Machine"模式的遥感影像数据共享实验,验证了模型的合理性和有效性。

Based upon the analysis of the remote sensing image metadata model research, the possibility of combining the traditional static metadata of dataset and the dynamic metadata of data service together to cater for the requirement of data sharing model development was pointed out. A remote sensing image metadata model supporting automatic data search and service integration via computer has been raised. The model was applied on RS image data sharing experiment with the pattern of ＂machine to machine＂. The result demonstrated that the model was reasonable and feasible.
