【 摘 要 】

The characteristics of remote sensing data are large amount, multi-source, heterogeneous and distributed storage, which have caused the difficulty of data integration and greatly restricts its application. Based on the characteristics of metadata information of remote sensing data, this paper constructs the distributed remote sensing metadata integration criterion and realizes the unified format conversion of multi-source remote sensing metadata. Secondly, it designs amulti-source satellite data fast access method based on XML to improve the capability of rapid updating of data resources of satellite data application system in a single direction; Finally, the feasibility and practicability of the research results are verified by taking the integrated water resources management and emergency demonstration system in the river basin as an example.
