Digital Topographic Map 1: 50 000 — Preliminary edition L3744 Potsdam

The preliminary edition consists of georeferenced grid data from the scanned topographic map 1: 50 000 (TK50). In the future, the DTK will be derived from the base DLM. The data is available in layers (single layer, essentially corresponding to the inks) or combined from them as sum layers. They are available in 9-10 content levels: Situation black, (construction areas), map names blue, garden areas, forest areas, water lines, water areas, relief (sand areas, border band restricted area, regional and long-distance transport, long-distance transport. The sheet corners are specified in pixel and UTM coordinates in an ASCII file, default resolution: 200L = 508 dpi. The data is provided free of charge via automated procedures or by self-collection. When using the data, the license conditions must be observed.本初步版本包含源自1:50000扫描地形图（TK50）的地理参考栅格数据。未来，DTK将基于基础DLM生成。该数据可按图层形式提供（单图层基本对应印刷色版），也可由多图层合并为综合图层。数据包含9至10类内容层级：黑色要素图层（含建筑区域）、蓝色地图注记图层、园林区域图层、森林区域图层、水系线状要素图层、水系面状要素图层、地形起伏图层（含沙地、边境带限制区、区域及长途交通、长途交通要素）。图幅四角的像素坐标与通用横轴墨卡托（UTM）坐标已在ASCII文件中注明，默认分辨率为200L=508 dpi。该数据可通过自动化流程免费获取，也可自行获取。使用该数据时，请遵守相关许可条款。
