| 摘 要： | 以TM543波段组合RGB近自然的色彩对南宁市进行三个不同时像的遥感粗分类。探讨遥感影像经过主成分分析后采用决策树方法逐层提取林地、耕地、草地、水体、道路、城镇、其他类等基本地物类型，后又用决策树的方法将分类好的单个地物逐层合并成一张分类图。对同一地区的三个不同时像的遥感图像进行比较，研究证明决策树方法简单、直观。

| Abstract: | Combines the RGB near natural color by the TM543 wave band to carry on three different time alike remote sensing thick classifications to Nanning.The discussion remote sensing image uses the decision tree method cascade extraction forest,farmland,grass,water,road,town,other kinds after the principal components analysis and so on basically the thing type.Latter will use the decision tree to combine the classify individually the thing to make a classified chart by the lamination.Carries on the comparison to t... |
