Abstract: This paper put forward an integrated management method of marine remote sensing data by integrating the technologies of WebGIS, spatial database and network communication. A realtime publication of marine remote sensing data was designed and realized which integrates the function of data browsing, data querying, data downloading, automatic batch uploading remote sensing data to database, automatic longdistance data distribution and so on. The network communication technology and the efficient and safe data transmission that is combination of the encryption and verification technology were discussed. The mechanism of doubleeffect database connection pool was also analyzed. The strategy was proposed that marine remote sensing data is visualized by integrating the technology of creating data files dynamically with the technology of visualization cache. Finally, the application results show the system can manage marine remote sensing data efficiently.
