Digital Topographic Map 1: 50 000 — Preliminary edition L4142 Zahna

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.本数据集预版本包含源自1:5万比例尺扫描地形图（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（单图层基本对应印刷用色层）提供，或由多个图层合并为合成图层。该数据涵盖9至10类内容层级：黑色现状图层（含建筑区域）、蓝色地图注记层、园林用地图层、林地区图层、水系线图层、水区域图层、地形地貌图层（含沙地、边界带限制区、区域与长途交通层、长途交通层）。图幅四角的像素坐标及通用横轴墨卡托（UTM）坐标将在ASCII文件中注明，默认分辨率为200L=508dpi。该数据可通过自动化流程或自助下载的方式免费获取。使用该数据时，需遵守相关许可条款。
