资源简介:

Water mains are large underground pipes that carry clean drinking water from the Council's supply to suburbs and streets. This layer supports asset management, maintenance, and planning of the water network. Data is continually updated as new information is received. The vertical datum used for this dataset is NZVD 2016. Dataset Fields (Columns): Compkey: Unique, auto-generated identifier for each asset (i.e., pipe segment). UnitID: Asset unit ID at the starting point of the pipe. UnitID2: Asset unit ID at the end point of the pipe. Diameter: Internal pipe diameter (in millimeters). Length: Total pipe length (in meters). Material: The material the pipe is made from. See material codes below. Material Codes and Descriptions: ABS: Acrylonitrile Butadiene Styrene AC: Asbestos Cement ALK: Alkathene CI: Cast Iron CICL: Cast Iron Concrete Lined CIEL: Cast Iron Epoxy Lined CLS: Concrete Lined Steel CU: Copper DIRN: Ductile Iron GS: Galvanised Steel HB: Hobas HC: Humes Concrete HDPE: High Density Polyethylene HPPE: High Pressure Polyethylene MDPE: Medium Density Polyethylene PE100: Polyethylene (Type PE100) PE80: Polyethylene (Type PE80) PVC: Polyvinylchloride RCRRJ: Reinforced Concrete Rubber Ringed Joint S: Steel SEL: Steel Epoxy Lined SWS: Spiral Welded Steel Notes: The "Updated" date you see on this item indicates when the metadata was last revised. It doesn’t necessarily reflect when the data inside the feature layer was last refreshed. The data available for download on Palmy GeoHUB is updated daily, this results in a difference between what’s currently visible online and PNCC’s databases.

供水干管是指将市政当局供应的洁净饮用水输送至郊区与街道的大型地下管道。本数据集可为供水网络的资产管理、运维与规划工作提供支撑。数据会随新信息的接收持续更新。本数据集采用的垂直基准面为NZVD 2016(New Zealand Vertical Datum 2016)。 数据集字段(列)如下: Compkey:用于标识每个资产(即管道段)的唯一自动生成标识符。 UnitID:管道起点处的资产单元编号。 UnitID2:管道终点处的资产单元编号。 Diameter:管道内径,单位为毫米。 Length:管道总长度,单位为米。 Material:管道制造所用材质,详见下述材质代码及说明。 材质代码与说明: ABS:丙烯腈-丁二烯-苯乙烯共聚物(Acrylonitrile Butadiene Styrene) AC:石棉水泥(Asbestos Cement) ALK:Alkathene CI:铸铁(Cast Iron) CICL:铸铁衬混凝土(Cast Iron Concrete Lined) CIEL:铸铁环氧内衬(Cast Iron Epoxy Lined) CLS:混凝土衬钢管(Concrete Lined Steel) CU:铜(Copper) DIRN:球墨铸铁(Ductile Iron) GS:镀锌钢(Galvanised Steel) HB:Hobas HC:Humes混凝土管(Humes Concrete) HDPE:高密度聚乙烯(High Density Polyethylene) HPPE:高压聚乙烯(High Pressure Polyethylene) MDPE:中密度聚乙烯(Medium Density Polyethylene) PE100:聚乙烯(PE100型)(Polyethylene (Type PE100)) PE80:聚乙烯(PE80型)(Polyethylene (Type PE80)) PVC:聚氯乙烯(Polyvinylchloride) RCRRJ:橡胶圈接口钢筋混凝土管(Reinforced Concrete Rubber Ringed Joint) S:钢材(Steel) SEL:环氧内衬钢管(Steel Epoxy Lined) SWS:螺旋缝焊接钢管(Spiral Welded Steel) 备注:本条目显示的“更新日期”指元数据的最后修订时间,未必反映要素图层内数据的最后刷新时间。Palmy GeoHUB平台可下载的数据每日更新,这会导致线上当前可见内容与PNCC的数据库存在差异。
