Visualization effect and service quality is pivotal for remote sensing data managing and applying. Based on analyzing characteristics of remote sensing data, we studied on data fragmentation and parallel scheduling to improve loading and downloading efficiency of remote sensing data. In this paper, a new method of the visualized management is proposed and used in the visualization management subsystem we developed. The method which is used in distributed storage system utilizes a pyramid model with multi-resolution to make remote sensing data visible and operable. Then, data processed by the visualization management subsystem is submitted to data promoting service subsystem of china manned space engineering for distribution and utilization. In consequence, the data promoting service subsystem accumulates mass of high-precision remote sensing data received from payloads of Tiangong-1 aircraft, Tiangong-2 space laboratory and Tianzhou-1 aircraft. To ensure security and service efficiency, the subsystem enhances identity authentication, authority management and database management on the basis of some previous work. Moreover, data exchange module, GIS-based visual data retrieval module and FTP-based file download tool are increased in the subsystem to meet the diverse requirements of scientists for remote sensing data sharing.
