The spectra of maize field are of great uncertainty duo to the difference in planting date, irrigation condition, fertilizing and soil etc. The spectral library is a quick means acquiring the crop spectrum in a growth stage. The variance of image and in-situ maize spectra is analysized for extracting pure pixels of maize crop. It presents a good result for(More)
Although the development of spectral library is hot at home and abroad since 90's in 20 centuries,It has defects and can't meet the demands of theory research and application of remote sensing nowadays. The gap is further extended for the featured agricultural remote sensing application in South China. Internationally, the foundation research of remote(More)
