从城市建设用地影像光谱信息入手,分析不同时期的Landsat TM、ETM+各波段上地物的谱间结构特征,利用图像处理软件,建立图像分类模型,自动分类与人机交互结合方式进行变化解译,得到济南市南部地区城市扩展动态变化信息;对该区城市扩展规律进行了简要分析。 更多还原

【Abstract】 From the spectrum information of urban construction land images, this paper analyzes spectral structure from various periods of landsat TM?ETM+; utilizing the software of image processing, builds the models of the image classification to interpret the changes by automatic classification and the integration of human and the machine. We get the dynamic changes information of Jinan southern region expansion, and briefly analyze the order of this city`s expansion. 更多还原
