Hydrogeologically relevant disturbances as a layer of the digital hydrogeological map 1:100 000. Zoom limit min 1:200 000 to max. 1:50 000. The dHK100 was created between 2000 and 2015 (planning region 14 Munich to 2019) according to planning regions. Technical map bases of all layers of the dHK100 and HK100 were i.e. the available geological maps on a scale of 1:25 000 and 1: 50 000 to the respective processing stage. Their geometries were partly generalised. There is no systematic update of the dHK100. Due to the planning region processing over longer periods of time, geometric and attributive inconsistencies can occur along the planning region boundaries. These are due to different basic geological maps from which the hydrogeological maps are derived. Geometries and legend units are designed for an overview scale 1:100 000 (1 cm on a map correspond to 1 km in nature) and are generally generalised. The dHK100 or HK100 is intended as a basis for large-scale considerations. It does not replace detailed examinations and assessments by a specialist office in the planning of local projects. Scale-related accuracy does not change due to the scale-independent visualisation possibilities of digital map works. For further interpretations that combine or intersect the map work with other spatial data sets, it should be noted that an intersection of spatial data of greatly different resolution or target scales or different type of attribuing can lead to implausible or difficult to interpret results.

本数据集为1:10万比例尺数字水文地质图的水文地质相关扰动图层,显示缩放范围为1:200000(最小)至1:50000(最大)。dHK100(即1:10万比例尺数字水文地质图)于2000年至2015年间按规划分区编制完成(其中慕尼黑14号规划分区的编制周期延长至2019年)。dHK100与HK100(即1:10万比例尺水文地质图)所有图层的技术制图基础,均采用对应处理阶段已公开的1:25000及1:50000比例尺地质图,其几何要素已进行部分概化处理。该数据集暂无系统性更新机制。由于各规划分区的编制周期跨度不一,规划分区边界沿线可能出现几何与属性不一致的问题,该问题源于编制所用的基础地质图存在差异。所有几何要素与图例单元均按照1:100000概览比例尺(地图上1厘米对应实地1千米)设计,并已进行常规概化处理。dHK100与HK100仅作为宏观尺度分析的基础数据,无法替代专业机构针对本地项目规划开展的详细勘查与评估工作。由于数字地图产品支持与比例尺无关的可视化功能,其与比例尺相关的精度并不会因此改变。若需将该地图产品与其他空间数据集结合或叠加开展进一步解译,需注意:若空间数据的分辨率、目标比例尺或属性赋值类型差异过大,叠加后可能产生不合理或难以解释的结果。
