This project focuses on the key technologies for multi-scale (MSc) remote sensing (RS) production and multi-source(MSu) remote sensing synergic inversion using remote sensing data with global terrestrial observing capability. The technologies will be integrated into a prototype software system with the guidance of quantitative RS production technical specifications and the software will be able to produce the global terrestrial quantitative RS products including radiation budget, vegetation,water and heat fluxes, and snow&ice related products. The success of this project will popularize the application of quantitativeRS products on forestry, agriculture, mining, and ecology. Several progresses have been made as follows: (1)Initiated tocompose technical specification on quantitative RS production, including production technical hierarchy, technical specification,and global gridding criteria. (2)MSu and MSc RS data normalization technologies have been making progress, including thegeometric correction technologies for moderate to low and moderate to high RS data, spectra normalization technology,atmospheric correction technology for moderate to high RS data. (3)MSu RS synergic inversion of terrestrial products were making progress, including defining the satellite networking schemes for different types of quantitative RS products and the software modules for radiation budget, vegetation, water and heat fluxes, and snow and ice related products. (4)Constructed the hardware and software environment for quantitative RS production software system research and development. Finished the normalization technologies integration for moderate to high resolution RS data. Finished the development of database subsystem and operational management subsystem. Finished the integration of quantitative RS production for 30 m resolution. (5)Produced some quantitative RS products for other projects and started an application at Poyang Lake area. (6)Published 27 papers including 10 SCI papers. Applied for 5 national invention patents.
