Study On System Of Management And Release Of Remote Sensing Image Based On Multiple Layer Architecture

With the rapidly developing of technology of computer network and database, the shares of information has been the inevitable trend of times developing. How to make the advanced technology of computer serve for remote sensing and geography information system better has been the times missions of survey researcher.In this paper, considering the requirement of shares of national basis information resource and management and release of remote sensing image, How to make use of large database桹racle to store and manage remote sensing image data is discussed. Combining oracle application server, A system of management and release of remote sensing image based on multiple layers architecture in oracle is put forward.First, multiple layers architecture and its characters are analyzed in the article.Second, the status quo of frames in image database currently is summarized, the methods are presented to utilize oracle and oracle interMedia subassembly to store and manage remote sensing image data through studying at length, then based on the studying on the frame and characters of Oracle application server(Oracle9i AS), the system frame of management and release of remote sensing image is put forward on a basis of oracle database > oracle interMedia subassembly and oracle application server.At last, several critical problems in the system have been described in detail. First, the technology of Java in oracle is analyzed. The method of oracle JDBC is implemented. Then, the technology of advanced image processing is discussed emphatically. The capability of Java advanced imaging(JAI) API functions is proved to be effective in practice, which provide important methods and means for showing and processing of remote sensing image in internet/intranet.
