已提出的遥感数字变化探测方法基本上可以归结为两大类:一种是分类后比较法(Postclassification Comparison Method),另一种是逐像元比较法(Pixel to Pixel Comparison Method),或者叫分类前变化探测法(Preclassification Change Detection M...

道路密度指数分析法有两类方法:基于光谱—空间结构的分类后比较法和基于光谱—空间结构的图像差值法。
The road density index analysis has two ways: the post-classification compare method based on spectral-spatial structure and the imagery difference method based on spectral-spatial structure.
最后采用分类后比较法对14年前后的土地利用类型进行动态监测,建立土地利用转换矩阵,以量化方式表示各种土地利用类型变化具体情况。
Finally, by the post-classification approach, the LUCC during 14 years was monitored and the land use transfer matrix was built which can exhibit how and how much every land use type change.
