Abstract Thematic information extraction approaches have always been the focus and hotspot in remote sensing study and application. The unsupervised classification method, the supervised classification method and the threshold method with spectral structure were used to extract paddy fields information of Longhai City based on Landsat-7 ETM⁺ imagery. The study indicates that each of the three methods has its advantages and disadvantages. Satisfying results have been achieved by the last two methods. The differences between paddy fields and other land-use types and the structures of different spectra have been analyzed adequately, and some regularities governing the separation have been obtained. The result of the threshold method with spectral structure seems to be the best of the three methods.
