Design And Implementation Of Remote Sensing Thematic Production In Operational Processing Control And Resource Allocation

Remote sensing thematic data production system for remote sensing space information technology topics production applications, which surrounds the topic of satellite remote sensing data products and processing requirements to achieve various topics application of remote sensing data for the purpose. At present, China’s remote sensing application system has taken shape, remote sensing applications have formed a certain scale, but still faces many problems, one of the main problems is currently no good thematic remote sensing image data production system, which not only limits the Remote Sensing data production scale, but also limits the application and promotion of earth observation and information technology. Dissertation topic of key technologies ecological production systems of remote sensing business management subsystem operation in the development and realization of the process involved in the research base, a comprehensive summary of the research work of domestic and foreign remote sensing data products, production systems, analysis of remote sensing data products demand business processes and functional requirements and trends related technology systems, remote sensing ecological environment around topics product processing, production, combined with the system upgrading research and development work, design and implementation of the sub-themes of remote sensing data production systems business operations management system, and ultimately the ecological thematic products business, large-scale production.Firstly, the manufacturing processes and production systems of remote sensing data system function remote sensing data products proposed research purposes and research background combined task: to design and implement a distributed cluster environment, to complete business processes on-demand, event-driven proactive service, large-scale production of ecological remote sensing thematic products business operation and management subsystem. By analyzing the business processes, combined with remote sensing data products business production model, implemented based on different thematic processing algorithms can be combined in a logical order according to the function of workflow technology to support multi-task design method of production, after a detailed description of the system design process given two business production process instance.Secondly, in-depth study of the on-demand business processes, business process organization management and resource scheduling of key technologies, and the corresponding solutions through problem analysis. After the system test showed that: design method is feasible and effective solution to the remote sensing data products in the production process curing systems, operational production level is not high, low data production efficiency.Finally, in the realization of the basic operation of the system, the summary of the current research results and shortcomings, and the prospect of further research work.
