Drainage Pipes

This layer shows location of drainage pipes within the Metropolitan Region and is provided for information only. A Pipe is defined as a link in the drainage network. It includes drainage pipes, open drains, culverts and subsoils etc. It can be owned by Main Roads WA or others.

Please note that Main Roads WA drainage data is provided for information only and the data may be inaccurate, incomplete or out-of-date. Please use as a reference only and verification is to be undertaken on site. 2. Confidence Rating has been assigned to individual assets to provide an indication of the accuracy of the data. However please note that this is only an estimated rating which should be used as a reference only. 3. Asset Owner – Please note that Main Roads WA drainage data includes multiple organisations’ interface drainage and, as a result, the ‘Asset Owner’ attribute is only to be used as a reference only as it may be inaccurate and should not be referred to as the source of truth. 4. Asset Types: a. Interfacing Structures i. Note that the drainage data includes interface points between Main Roads WA drainage structures and structures owned by other asset owners. However not all assets owned by other asset owners have been included. Please seek clarification from the respective asset owners if required. b. Ghost Link i. Ghost link can be used to represent an interfacing drainage network not owned by Main Roads WA. These are commonly used to simplify complex networks located downstream on route to the ultimate stormwater outlet destination.

本图层展示了西澳大利亚州大都会区域内排水管道的分布情况，仅供参考。本数据集中，管道（Pipe）被定义为排水管网中的链路单元，涵盖排水管道、明渠、涵洞以及底土排水设施等，其权属可属于西澳大利亚州主干道局（Main Roads WA）或其他主体。

数据字典如下：
- 管道编号（Pipe_No）：别名"Pipe No"，数据类型为字符串，字段说明为"由道路编号（Road_No）与唯一数据库编号以"."拼接得到，示例：H015.569"
- 资产权属方（Asset_Owner）：别名"Asset Owner"，数据类型为字符串，字段说明为"资产的权属方，例如西澳大利亚州主干道局（Main Roads WA）"
- 道路编号（Road_No）：别名"Road No"，数据类型为字符串，字段说明为"西澳大利亚州主干道局道路编号"
- 资产状态（Asset_Status）：别名"Asset status"，数据类型为字符串，字段说明为"资产功能状态，分为"运行中"与"非运行中""
- 数据状态（Data_Status）：别名"Data Status"，数据类型为字符串，字段说明为"野外勘测验证情况，例如"已验证"或"仅通过桌面采集获取资产""
- 管道类型（Pipe_Type）：别名"Pipe Type"，数据类型为字符串，字段说明为"管道类型（遵循D-SPEC标准）"
- 管道长度（Length）：数据类型为双精度数值，字段说明为"管道段长度，单位为米"
- 管径/宽度（Diameter_Width）：别名"Diameter/Width"，数据类型为长整型，字段说明为"管道直径或涵洞/非圆形排水设施的宽度，单位为毫米"
- 上游管内底高程（Up_IL）：别名"Upstream Invert"，数据类型为双精度数值，字段说明为"管道上游端的管内底高程，单位为米"
- 下游管内底高程（Dn_IL）：别名"Downstream Invert"，数据类型为双精度数值，字段说明为"管道下游端的管内底高程，单位为米"
- 制图备注（Mapping_Comments）：别名"Mapping Comments"，数据类型为字符串，字段说明为"与该管道段相关的补充说明，包括相关假设"
- 置信等级（Confidence_Rating）：别名"Confidence Rating"，数据类型为字符串，字段说明为"基于数字化采集该地理要素所使用的源数据赋予的置信等级"

免责声明：
1. 请注意，西澳大利亚州主干道局（Main Roads WA）提供的排水数据仅供参考，该数据可能存在不准确、不完整或过时的情况。仅可将其作为参考依据，实地验证工作需另行开展。
2. 已为单个资产赋予置信等级，以反映数据的准确程度。但请注意，该等级仅为估算值，仅可作为参考使用。
3. 资产权属方：请注意，西澳大利亚州主干道局的排水数据涵盖多个机构的接口排水设施，因此"资产权属方"属性仅可作为参考，其准确性无法保证，不应作为权属依据的事实来源。
4. 资产类型：
a. 接口结构
i. 本排水数据包含西澳大利亚州主干道局排水设施与其他资产权属方所有结构的接口点，但未涵盖其他资产权属方的全部资产。如有需要，请向对应资产权属方寻求澄清。
b. 虚拟链路（Ghost Link）
i. 虚拟链路可用于表示非西澳大利亚州主干道局所有的接口排水管网，通常用于简化通往最终雨水排放口的复杂下游管网。
