Annual Australian Shoreline Positions And Change Rates From 1988

Australia's 30,000 km coastline is monitored annually from 1988 to the present. The dataset provides shorelines and rates of coastal change derived from satellite data and tidal modeling by the Australian Ocean Data Network. It enables historical analysis and regular updates of coastal erosion and growth patterns.

Use Cases

• Model coastline response to sea level rise using annual shoreline positions from 1988 onward.
• Prioritize coastal management by evaluating historical rates of coastal erosion at local and continental scales.
• Assess impacts of extreme weather events by comparing shoreline positions before and after specific years.
• Support geomorphological studies by mapping patterns of gradual coastal change over decades.

Strengths

• Continental coverage of over 30,000 km of Australian coastline.
• Annual temporal resolution providing data from 1988 to the present.
• Derived from satellite data combined with tidal modeling for mean sea level consistency.

Limitations

• Specific row count, column details, and sample data are unavailable.
• The dataset's spatial resolution and positional accuracy are not specified.
• The license terms for use and redistribution are unknown.
