Digital hydrogeological map 1:100,000 - groundwater levels

Groundwater levels of important aquifers as a specialist layer of the digital hydrogeological map 1:100,000. It is recommended to display them together with the separate specialist layers for groundwater levels and bases for constructing the groundwater levels. Zoom limitation min. 1:200,000 to max. 1:50,000. Groundwater levels are lines of the same height of a groundwater surface or groundwater pressure area. The dHK100 was created in the period from 2000 to 2015 (planning region 14 Munich to 2019) according to planning regions. The basis for the creation of the groundwater balance is the knowledge of groundwater levels in boreholes, wells, groundwater measuring points and springs as well as in surface waters, which are interpolated to lines of the same height taking into account hydrogeological and hydraulic conditions. Inaccuracies in the construction of the groundwater levels result in particular from the uneven distribution of the exploration points. A systematic update of the dHK100 does not take place. Due to the planning region-wise processing over longer periods of time, geometric and attributive inconsistencies can occur along the planning region borders between the groundwater levels that meet there. These are due to different basic data from which the groundwater levels are derived. Geometries and legend units are designed for the overview scale 1:100 000 (1 cm on a map corresponds to 1 km in nature) and i. i.e. R. strongly generalized. The dHK100 or HK100 is intended as a basis for large-scale observations. It does not replace detailed investigations and assessments by a specialist office when planning local projects. The scale-related statement accuracy does not change due to the scale-independent visualization options of digital maps. For further interpretations that combine or overlay the map series with other spatial datasets, it should be noted that an overlay of spatial data with very different resolutions or different target scales or different types of attribution can lead to implausible results or results that are difficult to interpret.
