This study adopts 1:250 thousand scale image and RS classification map to set up forest landscape.
采用1：25万地形数据与RS分类图配合形成三维立体森林景观。
To combine the scheme and classification maps for a deliverable, a higher-level map can refer to both maps using a DITA map reference (see Figure 6).
要把方案图和分类图组合起来形成可以发布的内容，可以用dita图引用，在更高层次的图中引用这两个图(请参阅图6)。
Because the classification map is distinct from the scheme map, you can apply multiple schemes to the same classification without requiring changes to the classification.
因为分类图与方案图不同，所以不需要改变分类，就可以把多个方案应用到同一分类上。
