10-meter resolution annual elevation and exposure products for Australia's entire intertidal zone. The Australian Ocean Data Network generated this continental-scale dataset from open-source Landsat and Sentinel-2 satellite archives. It was last updated in April 2026.
Use Cases
- Model coastal erosion and sediment transport by analyzing annual changes in intertidal elevation data.
- Predict storm surge or tsunami inundation by integrating intertidal elevation data with bathymetric and topographic models.
- Map critical habitats like tidal flats and reefs by classifying intertidal exposure patterns and elevation.
- Study migratory shorebird pathways by characterizing the spatio-temporal exposure patterns of the intertidal zone.
- Investigate carbon storage potential in intertidal environments using elevation and habitat extent data.
Strengths
- Continental-scale coverage of Australia's entire intertidal zone.
- Annual products provide a time series for monitoring dynamic changes.
- High 10-meter spatial resolution from Landsat and Sentinel 2 satellite data.
Limitations
- Specific row counts, file sizes, and temporal date ranges are not provided.
- Data is derived from satellite imagery, which may have limitations in accuracy under certain atmospheric or tidal conditions.
- The product suite is described in HTML format, which may require technical expertise to access and process the underlying geospatial data.
