Digital Earth Australia Intertidal
<div>Intertidal environments contain many important ecological habitats such as sandy beaches, tidal flats, rocky shores, and reefs. These environments also provide many valuable benefits such as storm surge protection, carbon storage, and natural resources. </div><div> </div><div>Intertidal zones are being increasingly faced with threats including coastal erosion, land reclamation (e.g. port construction), and sea level rise. These regions are often highly dynamic, and accurate, up-to-date elevation data describing the changing topography and extent of these environments is needed. However, this data is expensive and challenging to map across the entire intertidal zone of a continent the size of Australia. </div><div> </div><div>The intertidal zone also forms a critical habitat and foraging ground for migratory shore birds and other species. An improved characterisation of the exposure patterns of these dynamic environments is important to support conservation efforts and to gain a better understanding of migratory species pathways. </div><div> </div><div>The <strong>DEA Intertidal </strong>product suite ( https://knowledge.dea.ga.gov.au/data/product/dea-intertidal) provides annual continental -scale elevation and exposure products for Australia’s intertidal zone, mapped at a 10m resolution, from Digital Earth Australia’s archive of open-source Landsat and Sentinel-2 satellite data. These intertidal products enable users to better monitor and understand some of the most dynamic regions of Australia’s coastlines.</div><div><br></div><div><strong>Applications</strong></div><div><br></div><div> - Integration with existing topographic and bathymetric data to seamlessly map the elevation of the coastal zone. </div><div> </div><div> - Providing baseline elevation data for predicting the impact of coastal hazards such as storm surges, tsunami inundation, or future sea-level rise. </div><div> </div><div> - Investigating coastal erosion and sediment transport processes. </div><div> </div><div> - Supporting habitat mapping and modelling for coastal ecosystems extending across the terrestrial to marine boundary. </div><div> </div><div> - Characterisation of the spatio-temporal exposure patterns of the intertidal zone to support migratory species studies and applications. </div><div><br></div><div><br></div><div><br></div>

- Purpose
-
The DEA Intertidal product suite maps the changing extent, elevation and topography of Australia’s exposed intertidal zone. It is the next generation of DEA’s intertidal products that have been used across government and industry to help better characterise and understand this complex zone that defines the interface between land and sea. Incorporating both Sentinel-2 and Landsat data, the product suite provides an annual 10m resolution elevation product for the intertidal zone, enabling users to better monitor and understand some of the most dynamic regions of Australia’s coastlines. Utilising an improved tidal modelling capability, the product suite includes a continental scale mapping of intertidal exposure over time, enabling scientists and managers to integrate the data into ecological and migratory species applications and modelling.

- Statement
-
<div>The DEA Intertidal product suite extends the concepts developed in the DEA Intertidal Elevation (NIDEM) product, integrating higher resolution 10 m Sentinel-2 data with the original 30 m Landsat data to create annual elevation models and exposure products for Australia’s intertidal zone. </div><div> </div><div>This shift to a more dynamic product suite is achieved through a pixel-based algorithm, replacing the waterline interpolation methods of NIDEM, and an improved tidal modelling process to better leverage the increased data resolution and density provided by the inclusion of Sentinel-2 data. </div><div><br></div>
