摘　　要：遥感技术快速发展带来了数据的多源异构问题。本文基于遥感数据的元数据信息,综合应用了当前数据集成中的多种技术手段,设计并实现了适合于不同环境的数据集成模型。通过选用本体模型解决了集成中的数据冲突问题;通过预先设置元数据的筛选条件,提供了智能化的快速数据查询机制。最后,以应急灾区遥感数据快速集成系统为例,验证了本文研究成果的可行性和实用性。Aiming at the problem of multi-source heterogeneous data brought about by rapid development of remote sensing technology, this article listed the current main available data integration technology, and then designed several integration frameworks under different individual condition. Based on the metadata information of the remote sensing data, it used the integration framework to solve the conflicts, at the same time combined the specific applications of remote sensing data, as a result of the above process, it provided an intelligent mechanism under the set of filtering criteria. After all, it took the integration framework of remote sensing data in emergency disaster-stricken as an example to indicate the feasibility of the research.
