Digital Topographic Map 1: 50 000 — Preliminary edition L2746 Feldberg

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.本预发布版本包含源自扫描比例尺1:50 000地形图（TK50）的地理参考栅格数据。未来，DTK将基于基础DLM衍生生成。该数据可按单个图层提供（单个图层基本对应原图的印刷色层），也可通过合并多个图层得到合成图层。其支持按9至10类内容图层分类输出，具体包括：地物黑色图层（含建筑区域）、蓝色地图注记图层、园地图层、林地图层、水系线要素图层、水系面要素图层、地貌图层（含沙地、边界带限制区域、区域交通与长途交通、长途交通）。图幅四角的像素坐标与UTM（通用横轴墨卡托，Universal Transverse Mercator）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免费获取，或支持自助采集。使用该数据时，须遵守相关许可条款。
