Annual Continental Intertidal Elevation Maps For Australia

Digital Earth Australia Intertidal provides annual continental-scale elevation and exposure products for Australia's intertidal zone. The data is mapped at a 10-meter resolution using Landsat and Sentinel-2 satellite imagery to monitor dynamic coastal environments.

Use Cases

• Integrate intertidal elevation data with existing topographic and bathymetric data to create seamless coastal zone elevation models.
• Use baseline elevation data for predicting impacts of coastal hazards like storm surges, tsunami inundation, or future sea-level rise.
• Investigate coastal erosion and sediment transport processes using annual continental-scale exposure patterns.
• Support habitat mapping and modeling for coastal ecosystems spanning the terrestrial to marine boundary.
• Characterize spatio-temporal exposure patterns of the intertidal zone to aid migratory species studies.

Strengths

• Continental-scale coverage of Australia's entire intertidal zone.
• Annual products provide a time series for monitoring change.
• High spatial resolution of 10 meters per pixel.
• Derived from open-source Landsat and Sentinel-2 satellite archives.

Limitations

• Specific row and column counts, sample data, and file size are unavailable for assessment.
• Data is provided in HTML format, which may require extraction and conversion for direct geospatial analysis.
• The license is listed as 'notspecified', requiring user verification before application.
