Wetland Extent and Types in Victoria, Australia, from 1970s-80s Aerial Photography

Victoria, Australia's wetland environments are mapped as polygons showing their extent and types. The data is based on aerial photography interpretation from the 1970s and 1980s, with wetlands classified by water regime and subdivided by vegetation or hydrologic attributes. It was created by the Department of Energy, Environment and Climate Action and is available under a CC-BY-4.0 license.

Use Cases

• Mapping historical wetland extent based on polygon boundaries derived from aerial photography.
• Classifying wetland types based on water regime categories mentioned in the description.
• Analyzing wetland sub-areas based on vegetation or hydrologic attributes described in the data.
• Establishing a baseline for wetland conservation and change detection using the 1970s-80s temporal coverage.

Strengths

• Polygon boundaries were derived from digitizing marked-up aerial photography interpretation.
• Wetlands are classified into primary categories and sub-areas based on specific environmental attributes.
• Data is provided in multiple geospatial file formats including SHP, GDB, and WFS.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• The data's temporal coverage ends in 1994, based on photography from the 1970s and 80s.
