Shoreline Dynamics Assessment

The project brief focuses on the analysis and comparison of reef island shorelines using a new digital product developed by Geoscience Australia as part of the Digital Earth Australia (DEA) Program. The DEA product automatically maps coastlines annually since 1988 using satellite imagery and tidal modeling. The project aims to evaluate the accuracy of this product by comparing it to manually digitized shorelines for three reef islands in the Great Barrier Reef (GBR). 

Key questions include the accuracy of the DEA coastlines, the sufficiency of annual shoreline data, potential systematic differences, and the feasibility of creating a dashboard for managers to visualize and query island changes. Available datasets include both manually digitized shorelines and various free resources.
