Research and implementation of the massive remote sensing image storage and management technology

Aiming at the requirement of satellites massive remote sensing image data storage and management,this paper discussed the key technical questions at massive remote sensing image data management.By the study,it put forward a quick indexing mechanism which is an image pyramid structure model based on a linear quad-tree technical way,and carried out the integrated management between remote sensing image data and metadata by the relational database technology.At the end of paper,it analyzed the technical ways of building a system of massive remote sensing image data management,and proved the practicality of that way through an experimental data test.
