DEA Coastlines 2023 Released

The latest release of the coastal dataset features annual shorelines for the year 2023, and new selectable styles is now available.

Digital Earth Australia (DEA) Coastlines combines satellite data with tidal modelling to map the typical location of the Australian coastline at mean sea level for every year since 1988. Resulting shorelines and detailed rates of change show how beaches, sandspits, river mouths, and tidal flats have grown and eroded over time.

An updated version of DEA Coastlines is now available and includes new 2023 continental-wide data for Australia’s coastlines. This latest update also adds new functionality to easily switch between annual shorelines and rates of change on DEA Maps.
