Digital Topographic Map 1: 25 000 — Preliminary edition 3939 Nedlitz

The preliminary issue DTK25-V consists of georeferenced grid data from the scanned topographic map 1: 25 000 (TK25). The new editions DTK25 are derived from the basic DLM — see DTK25. The data is available in layers (single layer, essentially corresponding to the inks) or combined from them as sum layers. They are available in 6 content levels: Situation black (e.g. floor plan, map names), map names blue, forest areas, water lines, water areas, relief — sand areas — border band restricted area. In the Berlin area 20 map sheets are exclusively used as topographic city map (TSK25) 1: 25 000 edited — see DTSK25-V. The sheet corners are specified in pixel and UTM coordinates in an ASCII file. Standard resolution: 200 lines per cm = 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.初步数据集DTK25-V包含源自1:25000比例尺扫描地形图（TK25）的地理参考栅格数据（georeferenced grid data）。新版DTK25数据集源于基础DLM，具体参见DTK25相关说明。数据可按单一图层提供（单一图层基本对应印刷色层），也可由多个图层合并为综合图层。其涵盖6类内容层级：黑色要素图层（如平面图、地图注记）、蓝色地图注记图层、林区、水系线要素、水域面要素、地貌——沙地——边界带限制区。在柏林区域内，有20幅图幅被专门用作1:25000比例尺城市地形图（TSK25），相关编辑细则详见DTSK25-V。各图幅的四角坐标以像素坐标与UTM坐标的形式存储于ASCII文件中。标准分辨率为每厘米200线，即508dpi。该数据集可通过自动化流程免费获取，亦支持自行获取。使用该数据集时，需严格遵守相关许可条款。
