Australia's 30,000 km coastline is mapped annually from 1988 to the present. The dataset combines satellite data from Geoscience Australia's Digital Earth Australia program with tidal modelling to map the typical location of the coastline at mean sea level for each year. It enables analysis of coastal erosion and growth trends at local and continental scales.
Use Cases
- Monitor and map rates of coastal erosion based on annual shoreline positions.
- Prioritize coastal management actions based on historical coastline change patterns.
- Model how coastlines respond to drivers like extreme weather events or sea level rise.
- Support 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 from 1988 to the present, enabling long-term trend analysis.
- Combines satellite data with tidal modelling to map the coastline at mean sea level.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
