The latest release of Digital Earth Australia (DEA) Coastlines shoreline data brings the available dataset up to the year 2022.
DEA Coastlines takes satellite data and combines it with tidal modelling to map the typical location of the Australian coastline at mean sea level, year by year for every year since 1988.
The result is a representation of the national shoreline along with detailed rates of change that reveal how beaches, sandspits, river mouths and tidal flats have changed over time.
The updated version of DEA Coastlines includes 2022 continental-wide data and builds on the Coastlines 2.0 release, which incorporated data for several offshore islands and exposed reefs that had not been covered in previous releases.
As of earlier this year, Landsat 9 data has been and will continue to be added to DEA Coastlines to provide imagery from 2022 onwards, with annual dataset updates expected to be released in July each year.
