[Abstract]:This project focuses on solving the key technologies of multi-source remote sensing collaborative inversion and multi-scale quantitative remote sensing product generation of global land surface integrated observation, and establishes the quantitative remote sensing product technology system of global land surface integrated observation.Integrated development of a new generation of global integrated observation land surface quantitative remote sensing product production prototype system to form a global high precision, multi-scale generality quantitative remote sensing product production capacity, promote generic quantitative remote sensing products in China mineral, forest, water,The application of resources and environment monitoring, such as grain, provides technical support for the operation of remote sensing monitoring of global resources and environment.With the joint efforts of all personnel, this year the project has made significant progress in the following areas: 1) the preliminary establishment of a common quantitative product production technology system, including the common product production technology system,Generic quantitative remote sensing products production standards and specifications, the global division standard of multi-scale data, etc., etc.) the key technology of normalization processing of multi-source and multi-scale remote sensing data has made a breakthrough, and the geometry of medium and high scale and middle and low scale has been developed.The radiation normalization technology, the spectral normalization technology of various data, the atmospheric correction technology of medium and high resolution data, etc.) the key technology of cooperative high-precision quantitative inversion of multi-source remote sensing has made a breakthrough.The scheme of satellite data networking for several kinds of general quantitative products has been determined. Key technical breakthroughs have been made in the aspects of radiation budget, vegetation structure and growth state, water and heat flux, ice and snow parameters, etc.The software module of part of the products is formed, and the hardware and software environment of the prototype system for the production of general quantitative remote sensing products is preliminarily built, the normalized processing technology of the medium and high resolution remote sensing data is integrated, and the database subsystem is completed.The research and development of transportation management subsystem has completed the integration of 30 m resolution generality quantitative remote sensing product production algorithm.The production capacity of medium and high resolution data processing capacity and 30m resolution generality quantitative remote sensing product is formed. The trial production and application demonstration of generic product are presented. Some common quantitative remote sensing products are produced for the application subject by using the algorithm developed by this subject.A preliminary demonstration of application was carried out in Poyang Lake area. 27 papers were published in academic journals at home and abroad, including 10 SCI papers and 5 domestic invention patents.
