摘要：
Recent years, orienting space platform to construct satellite-ground integrative spatial information network has become a hot topic of information network construction. Conventional information network construction tends to be flow driven to meet the communication requirement between nodes. The construction of spatial information network focuses more on taking tasks in the application business as guide, and pulls from communication resources to optimal recombination and cooperative ser-vice of computing and storage resources. How to form linkage mechanism between application tasks and limited network resources, which can effectively solve the capacity constrained problems of remote sensing data storage, processing and transmission, is the key technical problem to realize the efficient data processing in spatial information network. According to the mechanism of satellite-ground collaborative remote sensing data processing, based on the task driven spatial information network architecture, an approach of spatial information network oriented satellite-ground collaborative computing migration is presented. We build an optimization model of computing migration, propose the implementation technique of computing migration and verify the feasibility of the approach through results analysis of the simulation case. © 2019, Editorial Board of Geomatics and Information Science of Wuhan University.
