Ws Reservoir (OpenData)

WsReservoir represents a location or structure designed for the storage of water within the WaterSupply network (eg Reservoir, Suction Tank). When constructed on a hill, by virtue of being a large elevated volume of water, reservoirs also maintain pressure in the network below them. The Water Supply network is a pressurised system that distributes potable or non-potable water to properties for the purposes of consumption, irrigation and firefighting. It is spatially abstracted to an area and is a child on the Water Supply network. IDS-compliant WsReservoir data will be inserted via the WsReservoirStage table. When deleted or edited, the record is Archived. A snapshot of the feature record, before it is edited, will be sent to the archive table immediately prior to the first edit of the day for that record. Entity type: Thing.

储水设施（WsReservoir）指供水网络（WaterSupply network）中用于储水的场地或构筑物，例如水库（Reservoir）、吸水罐（Suction Tank）。若将其设置于山丘之上，凭借高位蓄水的特性，储水设施还可维持其下方供水网络的水压。供水网络是一套带压系统，可为各类场所输送饮用水或非饮用水，用于饮用、灌溉及消防作业。该储水设施在空间上被抽象为面要素，为供水网络的子节点。符合IDS标准的储水设施数据将通过WsReservoirStage表进行写入。该记录若被删除或编辑，则将被归档。针对该记录的当日首次编辑操作执行前，其编辑前的要素记录快照将被立即推送至归档表。实体类型：Thing。投影坐标系：新西兰横墨卡托投影（New Zealand Transverse Mercator, NZTM）——EPSG代码：2193。垂直基准面：2016年新西兰垂直基准面（New Zealand Vertical Datum 2016, NZVD2016）——EPSG代码：7839。
