摘要：This paper presents various limitations of the current remote sensing data distribution models and proposes a new concept called the location-based instant satellite image service for a new generation of remote sensing image distribution *** essential feature of the service is that customers can subscribe to data based on the location of interest and satellite image data received by antenna will be distributed to customer’s terminal devices instantly after imaging over the subscribed *** workflow,architecture,and key technologies of the new generation data distribution system are *** system is composed of four parts:data comprehensive processing component,data management component,product distribution component,and data display *** on this,a prototype system is developed,which demonstrates the promising service model with great potential for increased usage in many applications.
