Abstract


In recent years, multi-spectral , high spatial resolution the SPOT5 satellite remote sensing data is widely used in the monitoring of the ecological environment . Explore the theory and technology of remote sensing monitoring of the actual needs of the forestry production and ecological environment , especially to improve the accuracy of remote sensing data, small class area estimation , the current problems to be solved . In this paper, the characteristics of SPOT5 remote sensing data , according to the needs of the Tianjin sandstorm source project monitoring 2.5m , 10m resolution the SPOT5 satellite remote sensing images as a source of information , depth SPOT5 remote sensing data preprocessing , small class area in Estimating vegetation monitoring coverage , in an attempt to provide a scientific basis and technical support for SPOT5 remote sensing data in Beijing and Tianjin sandstorm source monitoring . The main results : ( 1 ) for the engineering characteristics of Beijing and Tianjin sandstorm source , ecological environment monitoring use of SPOT5 remote sensing data preprocessing methods . (2) interpretation of remote sensing models based on SPOT5 remote sensing data spectral structure information and historical survey data mining , and Yanqing County, Beijing and Tianjin sandstorm source projects in small classes the boundary extracted and area estimation . ( 3) The depth of vegetation coverage in Estimating small classes of vegetation coverage based engineering estimate . The results show that , SPOT5 remote sensing images used in the engineering areas of Beijing and Tianjin sandstorm source monitoring process can be efficient, fast , scientific access to higher analysis accuracy , Tianjin sandstorm source project monitoring through remote sensing data to auxiliary a scientific basis .
