Queensland Coastal Wetlands Vegetation Mapping, 1987-1997

Queensland Coastal Wetlands (Mangroves, saltpans, samphire), 1987 - 1997 (DEEDI) is a 1:100,000 scale vegetation map for the Queensland coastline. It was derived from automatic classification of 25m resolution Landsat TM images, aerial photography, and ground truthing, resulting in a positional accuracy of 100 meters and a classification accuracy of approximately 80%. The dataset is hosted by the Australian Ocean Data Network.

Use Cases

• Monitor mangrove community changes over time based on the 1987-1997 temporal coverage.
• Analyze the distribution of dominant mangrove genera (e.g., Aegiceras, Avicennia) based on the CLASS attribute.
• Assess the extent of saline habitats like saltpans and samphire-dominated areas for conservation planning.
• Validate remote sensing classification methods using the described 80% classification accuracy and ground truthing.

Strengths

• Includes a classification accuracy of approximately 80%.
• Provides a positional accuracy of 100 meters.
• Covers the entire Queensland coastline at a 1:100,000 scale.
• Derived from multiple sources including 25m resolution Landsat TM images and ground truthing.

Limitations

• Data currency varies by region, with some areas mapped as early as 1986.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
