Digital Earth Australia Coastlines is a continental dataset produced by Geoscience Australia's Digital Earth Australia program. It provides annual shorelines and rates of coastal change for the entire Australian coastline from 1988 to the present. The dataset combines satellite data with tidal modelling to map the typical location of the coastline at mean sea level for each year.
Use Cases
- Monitoring and mapping rates of coastal erosion based on annual shoreline positions
- Prioritizing coastal management actions based on historical coastline change trends
- Modeling how coastlines respond to drivers like extreme weather events or sea level rise
- Supporting geomorphological studies of how and why coastlines have changed across time
Strengths
- Continental-scale coverage of Australia's over 30,000 km coastline
- Annual temporal resolution from 1988 to the present
- Combines satellite data with tidal modelling for mean sea level mapping
Limitations
- Column-level documentation is absent; field semantics must be inferred after download
- Row count is unknown, which may limit suitability assessment
