Over 30,000 km of Australia's dynamic coastline is monitored in this continental dataset. Digital Earth Australia Coastlines combines satellite data from Geoscience Australia with tidal modelling to map annual shoreline positions at mean sea level from 1988 to the present. The product enables historical and current analysis of coastal erosion and growth trends at local and continental scales.
Use Cases
- Monitoring rates of coastal erosion based on annual shoreline positions
- Prioritizing coastal management actions based on historical coastline change patterns
- Modeling coastline response to drivers like extreme weather events or sea level rise
- Supporting geomorphological studies of how and why coastlines have changed over time
Strengths
- Covers the entire Australian coastline, over 30,000 km in length
- Provides annual shoreline data spanning from 1988 to the present
- Combines satellite data with tidal modelling for consistent coastline mapping
Limitations
- Column-level documentation is absent; field semantics must be inferred after download
- Row count is unknown, which may limit suitability assessment
