    摘要:

    利用最小二乘支持向量機(jī)良好的非線性劃分能力,基于資源一號02C高分辨率遙感數(shù)據(jù),,結(jié)合圖像形狀,、紋理特征等信息,,對農(nóng)業(yè)區(qū)土地利用類型進(jìn)行快速分類提取,,結(jié)果表明:資源一號02C高分辨率數(shù)據(jù)可以快速有效地實(shí)現(xiàn)土地類型劃分,,加入特征信息后的圖像分類精度大幅度提高,,而最小二乘支持向量機(jī)的分類結(jié)果也十分理想,,總體分類精度達(dá)到82.53%,,Kappa系數(shù)達(dá)到0.8071,高于傳統(tǒng)圖像分類方法,,為利用國產(chǎn)高分辨率衛(wèi)星進(jìn)行土地類型劃分提供了快速可行的方法,。

    Abstract:

    Applying the good nonlinear classification ability of the least squares support vector machine (SVM) algorithm, this paper conduced the classification of land use in agricultural district from the high-spatial resolution ZY1-02C remote sensing images, which was based on the SVM method integrating information of shape and texture. It shows that the high-spatial resolution ZY1-02C data can realize land classification quickly and effectively, and the classification accuracy is increased by adding the feature information. The least squares SVM classification results were ideal, the overall accuracy was 82.53%, and the Kappa coefficient was 0.8071. It has higher accuracy than traditional method and provides a feasible method for the classification of land use based on domestic high-spatial resolution satellite.
