Victorian Wetlands from the Directory of Important Wetlands in Australia

The 2001 third edition of the Directory of Important Wetlands of Australia provides the source listing for this geospatial dataset. It contains boundaries for wetlands in Victoria, Australia, derived from the 1994 wetland layer, hydrological data, and topographic maps, with updates in 2017 improving boundary accuracy. The dataset is published by the Department of Energy, Environment and Climate Action under a CC-BY-4.0 license.

Use Cases

• Map wetland conservation areas based on the listed important wetlands.
• Analyze changes in wetland boundaries based on the 2017 update from on-ground mapping.
• Conduct regional environmental assessments based on the integration of hydrological and topographic data sources.

Strengths

• Derived from the authoritative 2001 Directory of Important Wetlands of Australia.
• Boundary accuracy was improved for a number of wetlands based on a 2017 update involving on-ground mapping.
