Seasonal Herbaceous Wetland Likelihood Model for South-East Australia at 25m Resolution

South-east Australia is covered by a model predicting the likelihood of seasonal herbaceous wetlands. The dataset provides mean likelihood and uncertainty surfaces at a 25 x 25 meter pixel resolution, derived from 30 independent models using Landsat and ALOS satellite data and field observations. It was published by the Department of Energy, Environment and Climate Action and last updated on 2026-04-27.

Use Cases

• Mapping wetland habitat probability based on satellite-derived indices mentioned in the description
• Assessing model confidence for conservation planning based on the provided uncertainty surfaces
• Analyzing land cover change over time based on the temporally informed statistics used in the model
• Validating field observations of wetlands against satellite-based predictions

Strengths

• Provides both a mean likelihood surface and a standard deviation uncertainty surface for each prediction
• Model is informed by field observations and a suite of temporally informed satellite statistics
• Output is at a high spatial resolution of 25 x 25 meters per pixel
• License is CC-BY-4.0, allowing for broad reuse

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment for large-scale ML projects
