The evolution of Australia’s coastlines can now be seen in unprecedented scale and detail, via a new tool developed by Geoscience Australia’s Digital Earth Australia (DEA) program. Using satellite imagery collected since 1988, DEA Coastlines maps annual changes to Australia’s coastlines to highlight long-term trends in coastal erosion and growth.
The free online tool can also illustrate how natural coastal features like sandbanks or river mouths shift and change over time.
Geoscience Australia’s National Earth and Marine Observations Branch Head Maree Wilson said DEA Coastlines provides scientists, managers, and policymakers with new information to maintain and protect Australia’s iconic shores for future generations.
