Soil Landscapes of the Federal Republic of Germany 1:250,000

Small-scale soil maps are usually derived from large- or medium-scale soil maps by spatial generalization and content aggregation. A uniform pedoregional classification is required to ensure a comparable approach even across regions. The presented data set at the aggregation level of soil landscapes comprises the 36 most important lithogenetic units in Germany relevant to soil science and is essentially based on the Soil Map 1:200,000 (BUEK200) published jointly by the Federal Institute for Geosciences and Natural Resources (BGR) in cooperation with the National Geological Surveys (SGD) of the federal states and its soil landscape classification. Additionally included are the soils of larger settlement, industrial and commercial areas (as BGL 13.1) and the soils of post-mining landscapes (as BGL 13.2). More detailed information on the soil regions and soil landscapes of the Federal Republic of Germany can be found in the Soil Mapping Guide (KA5), chapter 6.5 starting on page 335. The digital map graphics are based on the topographic principles of the Digital Landscape Model 1:250,000 (DLM250) from 2014 of the Federal Agency for Cartography and Geodesy (BKG).小比例尺土壤图通常通过空间综合与内容聚合，由大、中比例尺土壤图衍生得到。为确保跨区域方法的可比性，需采用统一的土壤区域分类（pedoregional classification）。本次发布的以土壤景观聚合层级为基准的数据集，涵盖了德国土壤学领域内最为重要的36个岩性单元（lithogenetic units），其数据基础为联邦地球科学与自然资源研究所（BGR）与各州国家地质调查局（SGD）联合发布的1:20万土壤图（BUEK200）及其配套的土壤景观分类（soil landscape classification）体系。数据集还补充纳入了大型居住区、工业区及商业区的土壤（对应编码BGL 13.1）与采矿后遗迹景观的土壤（对应编码BGL 13.2）。如需获取德意志联邦共和国土壤区域与土壤景观的更多详细信息，可查阅《土壤制图指南（KA5）》第335页起的第6.5章节。本数字地图制图成果基于德国联邦制图与大地测量局（BKG）2014年发布的1:25万数字景观模型（DLM250）的地形制图原则。
