DEA Intertidal provides annual continental-scale elevation and exposure products for Australia's intertidal zone. The data is mapped at a 10m resolution from Digital Earth Australia's archive of open-source Landsat and Sentinel-2 satellite data. These products are maintained by the Australian Ocean Data Network.
Use Cases
- Predict coastal hazard impacts based on baseline elevation data.
- Investigate coastal erosion and sediment transport processes.
- Support habitat mapping and modelling for coastal ecosystems.
- Characterize exposure patterns to support migratory species studies.
