An exploring work was conducted on the meteorological data measured at 63 different stations in the Huanghe,Huaihe and Haihe(HHH)plain and NOAA AVHRR image.The crop water stress index(CWSI)was calculated every 1.1km in adaptive spatial resolution of NOAA AVHRR image.A linear interpolation was developed and optimum interpolation was selected to process the meteorological data.With the aid of GIS and the different processing to remote sensing image in raster data structure and map graph in vector data struc...
