Digital Landscape Model 50 (DLM50)

The DLM50 is derived from the basic DLM. This involves a generalization of the content as well as a simplification of the geometric structures. Due to the summary to a smaller number of object types and the omission of detailed representations, the DLM50 is suitable for applications with overview character in the regional area and for the derivation of topographical and thematic maps in scales 1 : 50 000 and 1 : 100 000.DLM50 源自基础DLM。这一衍生过程包含对内容的制图综合，同时对几何结构进行简化。由于将地物要素类型归并为更少的类别，并省略了细节化的表达，DLM50 适用于区域范围内的概览类应用，以及用于编制比例尺为1:50000和1:100000的地形图与专题地图。
