Erosion Hazardous Cards Free State of Saxony

In recent years, new data bases have been developed, which required a current assessment of the risk of erosion. Compared to the existing erosion hazard maps, spatially differentiated and updated erosion hazard maps are now available. The following data bases were incorporated into the present maps. They must be taken into account when using and interpreting the erosion hazard maps: Ground map in scale 1: 50,000 (BK50), source: Saxon State Office for the Environment, Agriculture and Geology (LfULG) 2020; Digital terrain model in 5 m grid (DGM5), generalised from DGM2, source: Geobase information and surveying Saxony (GeoSN) 2012; Precipitation series from 2001 to 2017, Source: German Weather Service (DWD) 2019近年来，新型数据库相继建成，亟需对土壤侵蚀风险开展最新评估。相较于现有侵蚀灾害风险图，当前已可获取经空间差异化且更新后的侵蚀灾害风险图。本次编制的侵蚀灾害风险图纳入了以下数据源，在使用与解读该风险图时，需将以下数据库纳入考量范围： 1. 比例尺1:50000的地面图（BK50），数据来源：萨克森州环境、农业与地质局（Saxon State Office for the Environment, Agriculture and Geology，LfULG）2020年； 2. 5米格网数字地形模型（DGM5），由DGM2简化生成，数据来源：萨克森州地理信息与测量局（Geobase information and surveying Saxony，GeoSN）2012年； 3. 2001年至2017年降水序列，数据来源：德国气象局（German Weather Service，DWD）2019年。
