Above ground water catchment areas Dresden (WMS Dienst)

The topic covers the Upper Earth River Basin Areas (EZG) for surface waters in Dresden, with at least one EZG defined for each flowing water, except for a few exceptions. On the outskirts of the city, passability to the entire Saxon dataset was established. The EZG’e were calculated using GIS tools (SAGA GIS 2.2.0, Quantum GIS 2.8.1, Geospatial Modelling Environment GME 0.7.3), among others, based on the following data: — GeoSN digital terrain models (DGM) with grid widths 0.5 m and 2 m (fly 2009) — Water network of the city of Dresden (with Elbe as polyline, as of 20.3.2015) — Catchment area dataset of the LfULG (Saxony-wide) — LfULG flow water dataset (ATKIS-based, Saxon-wide) The following data is displayed for each EZG: — GEWAESSER: Name of the water to which the catchment area belongs. — GEWAESSERSYSTEM: Overarching water system. This attribute is used, among other things, for the assignment to the corresponding water cover. If Gewaesser is a main water or a water does not flow into a larger water, at least partly in Dresden, then GEWAESSERSYSTEM=Gewaesser is — WAESSERKENNZAHL: Water code (GEWKZ) according to LAWA method for gewaessers — AREA CODE: Encryption of the EZG with area code (GEBKZ) according to LAWA method = unique numbering of the EZG, coordinated with the total Saxon dataset. — START/END: Start and end of the EZG in relation to the waters to which the catchment area belongs. Start=source and ENDE=Earth in... states that it is the total undivided EZG of the corresponding water. — FLARE: EZG area in m² — AEND: Date of the last change — STATUS: Status, A=current — CATTIME: unique internal numbering of the graphic object — KATNAM/TYPE: other internal names for the graphic object本数据集主题覆盖德累斯顿市地表水域的上游流域区域（EZG，Upper Earth River Basin Areas），除少数例外情况外，每条地表径流均对应至少一个上游流域区域。 在德累斯顿市郊，该数据集已实现与全萨克森数据集的全互通关联。EZG通过GIS工具（包括SAGA GIS 2.2.0、Quantum GIS 2.8.1、地理空间建模环境GME 0.7.3等）计算生成，计算依托的基础数据如下： — GeoSN数字地形模型（DGM），网格分辨率分别为0.5米与2米（飞行测绘时间为2009年） — 德累斯顿市水系网（以易北河作为折线要素，数据截止至2015年3月20日） — 萨克森州全域流域数据集（LfULG出品） — LfULG地表径流数据集（基于ATKIS标准，覆盖萨克森州全域） 针对每个EZG，将展示以下属性信息： — GEWAESSER：该流域所属水体的名称。 — GEWAESSERSYSTEM：上层水系。该属性主要用于匹配对应的水体覆盖类型。若某水体为主河道，或该水体（至少在德累斯顿市域范围内）未汇入更大水体，则GEWAESSERSYSTEM与该水体名称（GEWAESSER）保持一致。 — WAESSERKENNZAHL：依据LAWA方法编制的水体编码（GEWKZ）。 — AREA CODE：依据LAWA方法编制的流域区域编码（GEBKZ），即与全萨克森数据集统一协调的EZG唯一编号。 — START/END：该EZG相对于所属水体的起止节点。若START为水体源头且END标注为"汇入……"，则表明该EZG为对应水体完整未拆分的上游流域区域。 — FLARE：EZG的面积，单位为平方米。 — AEND：最后一次修改的日期。 — STATUS：数据状态，其中"A"代表当前有效版本。 — CATTIME：图形对象的唯一内部编号。 — KATNAM/TYPE：该图形对象的其他内部命名。
