摘要
对遥感影像TM进行了全面的处理,利用沙化土地及其背景地物的光谱曲线差异,对其反射率均值特征和光谱谱间结构特征进行了分析,进一步建立了适合沙化土地信息提取的信息模型。实例证明该模型的提取精度为86.733%。
TM remote sensing images was comprehensively processed. Its mean reflectance characteristics and the structural characteristics of spectra have been analyzed using the spectral curve difference between the sandy land and its background features. An information model has been established, which is suitable for information drawn from desertified land. examples show that its extraction accuracy is 86. 733%.
