Abstract


Current domestic and international roaming Internet-based system is very large, but they are created for a particular purpose , use objects are professionals in the field of remote sensing , it developed a set of figures on a regional basis to expand the area of ??software applications are very targeted significance . The amount of remote sensing data , but with the new sensing technology, remote sensing images of the time , space, and spectral resolution continues to improve, is growing at a rate exponentially . Meanwhile , Internet technology allows the rapid development of remote sensing image data through the network sharing has become a reality . But the massive image data sharing between the network has limited bandwidth constitutes a sharp contradictions . This software platform developed digital area is an Internet-based remote sensing image roaming system , massive remote sensing image compression and transmission problems affecting the image became a key factor in roaming performance . Software platform combined with the characteristics of the digital area , a good solution to mass remote sensing image compression and transmission problems and improve system performance is roaming aim of this study lies. In this paper, Organization of massive image data management and sharing of research based on the development of the proposed and implemented software solutions. Which uses a new generation of still image compression standard JPEG2000 compressed image , using the image dynamic compression combined with static compression , but based on C / S (Client / Server) mode to transfer remote sensing image data, providing the client with the server to the storage area roaming remote sensing images and other operations . In remote sensing image data compression before storage , but also took a picture of the image data block and pyramid model for processing, image compression, and conducive to further facilitate the transmission through the network show , in addition , the client also designed and implemented based on multi-threaded cache mechanisms to improve performance. Final adoption papers relevant test data analysis of the program 's feasibility , final submission software infrastructure platform digital region realize results.
