ATKIS Digital Topographic Map 1:50 000 (DTK50)

The Digital Topographic Map 1:50 000 (DTK50) presents in generalized form selected topographic contents of the DLM50, elevation information (altitude lines and elevation points) and generalized building polygons from ALKIS according to the product standard for the DTK50 of the Working Group of Surveying Administrations (AdV).
The DTK50 is available in the form of georeferenced raster data in color- and content-separated layers (single layers) or in monochrome (grey) or color combination (sum layers) in any resolution (between 100 and 200 lines/cm, i.e. 256 to 508 dpi), according to the product and quality standard for Digital Topographic Maps, version 1.0, the AdV.
The raster data can be provided in the sheet section of the DTK50 or as sheet-cut-free preparations in the UTM coordinate system nationwide or in sections for the federal state of Baden-Württemberg.

1:5万数字地形图（Digital Topographic Map 1:50 000，DTK50）依据测绘管理工作组（Working Group of Surveying Administrations，AdV）制定的DTK50产品标准，以概括化表达方式呈现DLM50中的精选地形要素、高程信息（等高线与高程点），以及源自ALKIS的概括化建筑多边形。
DTK50可按照AdV发布的《数字地形图产品与质量标准V1.0》，以地理参考栅格数据形式提供，支持分色分内容图层（单图层）、单色（灰度）或色彩合成（汇总图层）格式，分辨率可按需设置（范围为100~200线/厘米，对应256~508dpi）。
该栅格数据可按DTK50图幅分区提供，也可采用无图幅裁切的通用横轴墨卡托坐标系（Universal Transverse Mercator coordinate system，UTM）数据形式，覆盖全国范围或巴登-符腾堡州的指定区域。
