| Abstract: | The capacity and accuracy of the disaster early warning and monitoring capabilities can be improved by the research on the disaster reduction using Chinese HJ-1A hyperspectral data.At the same time,the scope of the domestic satellite hyperspectral data applications can be expanded.The parameters of HJ-1A hyperspectral data are introduced and the principles of disasters monitoring using hyperspectral data are elaborated in this paper.Then the application status and potential of HJ-1A hyperspectral data are analyzed and evaluated in the field of disaster reduction.The results indicate that HSI data can meet the need in the early warning and monitoring of the drought,flood,snow and ice hazards,geological hazards and biological hazards. Finally,the pressing problems in the processing of HJ-1A hyperspectral data are pointed out.The first problem is to improve the data parameters,the second is to improve the data progressing procedure,and the third is to build the spectra library. |
