Digital Topographic Map 1: 25 000 — Preliminary edition 2940 Blumenthal

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.预发布版DTK25-V源自比例尺1:25000的扫描地形图（TK25）的地理参考网格数据。DTK25的新版数据源自基础DLM——详见DTK25。该数据可按图层提供（单图层基本对应印刷油墨色层），也可由多图层合并为复合图层。其包含6类内容层级：黑色要素图层（含平面图、地图注记等）、蓝色地图注记图层、林区图层、水系线图层、水域图层、地形、沙地及边界带限制区图层。在柏林区域内，20幅地形图幅被专门用作经编辑的1:25000比例尺城市地形图（TSK25）——详见DTSK25-V。图幅四角的坐标以像素坐标系及UTM (Universal Transverse Mercator，通用横轴墨卡托) 坐标系的形式存储于ASCII文件中。标准分辨率为200线/厘米，即508dpi。该数据可通过自动化流程免费获取，也可通过自助方式获取。使用该数据时，必须遵守相关许可条款。
