Digital elevation model Hamburg Schummerungskarte / terrain relief

The Schummerungskarte is a greyscale 2D image of a terrain created from 3D data (DGM1) for the area of the Free and Hanseatic City of Hamburg (excluding the area of the Hamburg Wadden Sea). The interplay of terrain heights and inclinations combined with a distant light source create a relief-like topography that visualizes a lively surface structure without absolute height values.
In areas of buildings and shading (bridges), dense vegetation, especially areas in forest and shrub areas, the generated surface structure may differ.
To counteract this effect, the representation is superimposed with the ALKIS building floor plans.

晕渲地形图（Schummerungskarte）是基于三维数据（DGM1）生成的灰度二维地形图像，覆盖范围为自由汉萨汉堡市辖区（不含汉堡滩涂海域区域）。该图像通过融合地形高程与坡度信息，并结合远距光源渲染效果，生成类浮雕的地形形态，可直观展现生动的地表结构，且未附带绝对高程数值。在建筑物、阴影区域（含桥梁区域）以及茂密植被区域（尤其是森林与灌丛片区）中，生成的地表结构可能存在偏差。为抵消此类偏差，该图像会叠加ALKIS建筑平面图进行修正。
