Annual shoreline positions and rates of coastal change for the entire Australian coastline from 1988 to the present. The dataset is produced by Geoscience Australia's Digital Earth Australia program, combining satellite data with tidal modelling to map the typical location of the coastline at mean sea level for each year. It enables the examination of trends in coastal erosion and growth at both local and continental scales.
Use Cases
- Monitoring and mapping rates of coastal erosion based on annual shoreline positions.
- Prioritizing coastal management actions based on historical coastline change analysis.
- Modeling how coastlines respond to drivers like extreme weather, sea level rise, or human development.
- Supporting geomorphological studies of how and why coastlines have changed across time.
Strengths
- Covers over 30,000 km of Australian coastline.
- Provides annual data from 1988 to the present, enabling long-term trend analysis.
- Combines satellite data with tidal modelling for consistent 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.
