Studies on Distributing Geo-information Sharing System
遥感地学信息的分布式共享系统研究

Remote sensing image contains plenty Geo-information. Issuing the Geo-information on the Internet is a basic component of sharing RS Image's Geo-information. The most important of issuing the information is to organize and manage RS image data efficiently according to their characteristics and peculiar Geo-information it them. According to the properties of multi.sensor, multi-resolution, multi-spectrum and multi-epoch of RS image data and their peculiar Geo-information. This paper has constructed a solid index mechanism of "Pyramid, Block, Layer, Epoch" according to the properties of RS image data and established corresponding logic relation databases for RS image data. The Geo-information of RS image data is reorganized via the solid index mechanism and logic database. Finally, the above ideas are used in setting up an image database system to provide query and search for Geo.information on the Internet.
