Application Research and Implementation of Drought Monitoring by HJ-1A/1B Satellites

By using the HJ-1A/1B satellites sensor data,this paper analyzes the advantages and disadvantages of some drought monitoring models for implementation.On this basis,we selected Fuxin City,Liaoning Province,as a study area,and realized the Perpendicular Drought Index (PDI) with HJ-1B CCD data.The results show that the HJ-1A/1B satellites data can be effectively used in drought remote sensing monitoring application.
