WMS LGRB-BW INSPIRE GE HG: Hydrogeological units – INSPIRE Display Service for Baden-Württemberg

The INSPIRE representation service of the hydrogeological units ge_hg_v visualises the hydrogeological units without top layers for Baden-Württemberg (HKoD_BW), as shown in the LGRB from the Geological Map (GK_BW or GK50; ge_gk) was derived. The GK_BW is under constant revision, so that the HKoD_BW is also updated at irregular intervals. The hydrogeological units of the HKoD_BW are differentiated according to their permeability in aquifers (Aquifers, Layer Aquifer Types) and aquifers (Aquitard, Layer Aquitard Types), which are included as separate layers in the service. The data layers Aquifer and Aquitard together form a comprehensive map basis. Special attention was paid to the spread of quaternary loose rock aquifers. An aquifer type is assigned to each hydrogeological unit (cavity type: Pore aquifers, clefts, karsts or mixed aquifers), which coarsely characterise rocks (hydrogeochemical rock type: silicate, carbonate, etc.) and an estimate of mean permeability or permeability ranges (permeability).ge_hg_v 标识的水文地质单元（hydrogeological units）INSPIRE表示服务，可针对巴登-符腾堡州的HKoD_BW数据集，可视化呈现去除顶层的水文地质单元；该数据集源自基于地质图（GK_BW或GK50；ge_gk）生成的LGRB。 GK_BW处于持续修订状态，因此HKoD_BW也会不定期进行更新。 HKoD_BW的水文地质单元依据其在含水层（aquifer）与弱透水层（aquitard）中的渗透性进行划分，其中含水层包含层状含水层类型（Layer Aquifer Types），弱透水层包含层状弱透水层类型（Layer Aquitard Types），上述两类均作为独立图层集成于该服务中。 含水层与弱透水层这两个数据图层共同构成了完整的地图基底。 本次服务特别关注了第四系松散岩类含水层（quaternary loose rock aquifers）的分布情况。 每个水文地质单元均会被赋予一种含水层类型，其空隙类型可分为孔隙含水层、裂隙含水层、岩溶含水层或混合含水层；该类型可粗略表征岩层的水文地球化学岩性（hydrogeochemical rock type，硅酸盐岩、碳酸盐岩等）以及平均渗透性或渗透性范围（permeability）。
