Victorian Wetland Inventory: 38,799 Polygons Across 784,120 Hectares

A 2013 geospatial inventory of wetlands in Victoria, Australia, updated in 2014, 2017, and 2021. The dataset from the Department of Energy, Environment and Climate Action consists of 38,799 polygons totaling 784,120 hectares. Wetlands are classified by system type, salinity, water regime, source, vegetation, and origin.

Use Cases

• Map wetland extent and distribution across Victoria based on polygon data.
• Analyze wetland types and ecological characteristics based on classification attributes like salinity and vegetation.
• Monitor changes in wetland boundaries over time based on updates from 2014, 2017, and 2021.
• Support regional conservation and land-use planning based on the detailed spatial inventory.

Strengths

• 38,799 individual wetland polygons provide detailed spatial coverage.
• 784,120 hectares of total mapped wetland area offers a substantial resource.
• Multiple updates (2014, 2017, 2021) indicate ongoing refinement and correction of the data.
