Historical land use in Lower Saxony 1: 25 000 (WMS service)

Maps of Historical Land Use in Lower Saxony 1: 25 000 show the condition before and at the beginning of the great cultivation measures of the 20th century. In order to be able to obtain as accurate and interpretable statements as possible on historical land use, the State Office for Mining, Energy and Geology (LBEG) evaluates old topographic maps from the period of the 18th to the beginning of the 20th century. The LBEG adapts the displayed land uses into the current topographies and keeps them available for further evaluations after digital recording in the database. From these data on land use at that time, evidence of soil development can be obtained as well as the distribution of wetlands or bogs reconstructed.下萨克森州1:25000比例尺历史土地利用地图，展现了20世纪大规模垦殖措施实施前及实施初期的土地状况。 为尽可能精准且具备可解释性地获取历史土地利用相关严谨结论，下萨克森州采矿、能源与地质国家办公室（State Office for Mining, Energy and Geology，缩写LBEG）对18世纪至20世纪初的老旧地形图开展评估工作。 LBEG将地图所呈现的历史土地利用信息适配至当前地形基准，经数字化录入数据库后予以存档，以供后续评估研究使用。 依托这批历史土地利用数据，不仅可获取土壤发育相关佐证信息，还能重建湿地或沼泽的空间分布格局。
