Drain and Waterway Outlet Locations in Greater Melbourne

Featuring geographic points representing drain and waterway outlet locations within the Greater Melbourne region, including the Port Phillip Bay and Western Port coastlines. The data was created from the Vicmap Hydro streams dataset for catchments greater than 60 hectares and has been maintained using Lidar survey data. The author is the Melbourne Water Corporation.

Use Cases

• Map outlet locations using geographic coordinates for spatial analysis of drainage networks.
• Analyze the distribution of waterway endpoints relative to the 60-hectare catchment threshold used in data creation.
• Integrate outlet point data with other geospatial layers like the original FIS 1:50K waterway (Reach) layer for hydrological modeling.

Strengths

• Data creation involved a rectification project from 2001-2003 to review and correct the waterway reach network.
• Maintenance and updates have been performed using Lidar survey data (contours).
• The dataset covers the Greater Melbourne region, including the Port Phillip Bay and Western Port coastlines.

Limitations

• The dataset includes only waterways within catchments greater than 60 hectares, potentially omitting smaller features.
• Point locations are described as indicative, which may imply positional inaccuracies.
• The disclaimer notes the provider makes no guarantees as to the accuracy or completeness of the data.
