In the view of the global resources and environment monitoring requirements, this task will integrate and make a breakthrough on a number of key technologies that have been achieved within ＂The first phase＂ such as Remote sensing satellite database distributed networking technology, Multi--scale remote sensing data assimilation and authenticity inspection technology, and Remote sensing data fusion processing and generating technology towards application~ And furthermore, this task will play an important role in the project named the second phase comprehensive ＂Satellite--Aerospaceplane--Groundstation＂ quantitative remote sensing system and application. In the above problems, we would pay attention to do some key breakthroughs in the process of building a multi--source remote sensing common production system and develop a comprehensive ＂Satellite--Aerospaceplane--Groundstation＂ quantitative remote sensing data fusion processing and general production system. The main research contents in this year are as follows： （1）More than 6 remote sensing satellite data centers will be connected together, in the meanwhile, virtual network distributed satellite data service system will be established based on some research results achieved in ＂The first phase＂ project. （2）Related technologies will be researched such as multi--source remote sensing data normalization of radiation, geometry normalization, quantitative remote sensing inversion, ＂Satellite--Aeroapeeplane-- Groundstation＂ observation data assimilation, seamless integration and space--time multi--scale real validation. Another important job is how to integrate Virtual network distributed satellite data service system, Multi--source remote sensing data normalization of radiation system, Multi--source remote sensing data geometry normalization system, Multi--source data fusion of quantitative remote sensing products production system, Multi--source data fusion products production system, Temporal continuous assimilation system common products, Quantitative remote sensing product authenticity test system, and Multi--center collaborative the massive remote sensing data processing support system. Among them, the top--level design, system demand analysis, and system general design would be included.
