Melbourne drain and waterway outlets

<p><span style='font-size:9.0pt;font-family:&quot;Verdana&quot;,sans-serif;
color:black'>This data contains points representing drain and waterway outlet
locations, associated with a natural waterway or channel centreline, within the
Greater Melbourne region. This region includes the Port Phillip Bay and Western
Port coastlines. Points are captured to show the indicative location of the
endpoint for a waterway or channel as geographic coordinates.</span></p>

color:black'>Data was created using the waterway (Reach) layer from original FIS
1:50K (Vicmap Hydro) streams data set, which included only those waterways
within catchments of greater than 60ha. Waterways (Reach) Rectification project
undertaken 2001 to 2003 to review and correct the extent of the waterways reach
network to ensure a complete data set exists (using the Drainage Metropolis
Boundary, 50K data, 1:2500 Drainage Record Plans, Drainage Limits data,
orthophotos, as constructed and/or design drawings, contour data and Melway
Street Directory). Waterway (Reach) extents defined and attributes populated in
GIS and AMIS for all records including assigning nodes and node numbers (for
start / end points) and removing any reaches less than 100 metres in length
that are predominantly channel assets. Waterways in extended area incorporated
in 2005 using Vicmap Hydro data and aerial imagery, then updated in 2009/10
using Lidar survey data (contours). Data is maintained using Lidar survey data
(contours) and 60 ha limits. Please refer to metadata for each dataset row
record for specific source / accuracy information.</span></p>

本数据集收录大墨尔本地区内排水口与水道出口的点位数据，所有点位均关联天然水道或河道中心线，覆盖范围包含菲利普港湾（Port Phillip Bay）与西港（Western Port）海岸线。数据点位以地理坐标形式记录，用于展示水道或河道端点的示意位置。

本数据表仅配置极简属性字段，用于辅助识别该地理要素。

本数据集源自原始FIS 1:50K（Vicmap Hydro）溪流数据集的水道（Reach）图层，该原始数据集仅收录集水面积大于60公顷的水道。2001至2003年间，项目团队开展了水道（Reach）整改工作，对水道河段网络的空间范围进行复核与修正，以保障数据集的完整性，所用参考资料涵盖：都市排水边界、5万比例尺基础数据、1:2500比例尺排水记录图、排水界限数据集、正射影像、竣工与/或设计图纸、等高线数据以及Melway街道名录。后续团队在地理信息系统（GIS）与资产管理信息系统（AMIS）中为所有记录完成水道（Reach）范围界定与属性填充，包括为起止节点分配编号，并移除长度不足100米且以河道设施为主的河段。2005年，项目团队通过Vicmap Hydro数据集与航空影像纳入扩展区域内的水道数据，并于2009至2010年利用激光雷达（Lidar）测量等高线数据完成更新。本数据集当前以激光雷达（Lidar）测量等高线数据与60公顷集水面积阈值作为维护更新依据。如需获取单条记录的具体数据源与精度信息，请查阅对应元数据。
