Digital Topographic Map 1: 25 000 — Preliminary edition 2739 Gerdshagen

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.初步版本DTK25-V由扫描生成的1:25000比例尺地形图（TK25）的地理参考栅格数据构成。新版DTK25数据集源自基础DLM——详见DTK25。数据可按单一图层（本质对应印刷色层）提供，亦可由多个图层合并为合成图层。其包含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、水域、地貌——沙地区域——边界带限制区域。在柏林区域内，有20幅地形图专门作为1:25000比例尺城市地形图（TSK25）进行编制——详见DTSK25-V。图幅四角的像素坐标与UTM坐标已在ASCII文件中列明。标准分辨率为每厘米200行，即508 dpi。该数据可通过自动化流程或自助方式免费获取。使用该数据时需遵守许可协议条款。
