[Abstract]:According to the requirement of global resource and environment monitoring, as a part of the project of "Satellite and ground Integrated quantitative remote Sensing system and Application demonstration (Phase II)", this project will integrate and break through the distributed network technology of satellite database formed in "Phase I" research. The key technologies such as multi-scale remote sensing data assimilation and authenticity verification, application oriented remote sensing data fusion processing and generation technology, and so on, are emphasized to break through a series of related technologies in the construction of operational multi-source remote sensing common product production system. A system of satellite-earth integrated observation quantitative remote sensing data fusion and common product production is developed. Based on the related technical achievements of the first phase of the project, the capability of connecting more than 6 satellite data centers is preliminarily realized, the distributed satellite data service system based on virtual networking is established, and the radiation normalization and geometric normalization of multi-source remote sensing data are studied. Quantitative remote sensing product inversion, satellite and earth observation data assimilation, space-time seamless fusion and multi-scale reality verification are applied to the distributed satellite data service system, the multi-source remote sensing data radiative normalization system, and so on. Multi-source remote sensing data geometric normalization system, multi-source data fusion quantitative remote sensing product production system, multi-source data fusion product production system, time continuous generality product assimilation system, quantitative remote sensing product authenticity testing system, Eight subsystems of multi-center mass remote sensing data collaborative processing support system are designed, including top-level design, requirement analysis and summary design.
