Geomorphographic Map of Germany

The relief of the earth's surface is a major controlling factor for ecological processes and a key indicator of the distribution patterns of important geological factors such as soil, rock and water. On the basis of a digital elevation model with a grid size of 250 meters, the company scilands GmbH in Göttingen produced on behalf of BGR the geomorphographic map of Germany. The programs SARA (System for Automatic Terrain Analysis) and SADO (System for Analysis and Discretization of Surfaces) determined 25 discrete geomorphograpic units (sink areas, closed hollow forms, slope areas, parietal areas, overlay forms) in four different landscape areas (North German Lowland, highland, Alpine foothills and Alps).地表地形起伏是生态过程的核心控制因子，同时也是土壤、岩石、水体等重要地质要素分布格局的关键指示指标。本数据集的制作基础为网格尺寸250米的数字高程模型（Digital Elevation Model），由哥廷根的scilands GmbH公司受BGR委托完成德国地貌图的编制。随后，借助SARA（自动地表分析系统，System for Automatic Terrain Analysis）与SADO（地表分析与离散化系统，System for Analysis and Discretization of Surfaces）两款程序，研究人员在北德低地、高地、阿尔卑斯山麓地带及阿尔卑斯山脉四类不同景观区域中，识别出25种离散地貌单元，包括汇水区、封闭洼地、坡地区域、崖壁区域与叠加地貌体。
