Application of CBERS-02 CCD data in flood monitoring——a case study of Xincai, Henan province

Abstract：In order to statistic water flood information, the spectral reflectance characteristics of different depth water was analyzed in flood period、Reflection characteristic of different objects on CBERS-02 CCD data was given a comparative analysis.By model building on ERDAS software, the water area was extracted of 2, 3, 4 bands in CCD data.The extracted result was given a contrast with history remote image to analyse the water change, and maps of basic informational layers were superposed by using GIS technology for analysis and operations.The monitor result was credible and accorded with the truth.
