The shoreline is a dynamic feature. Multi-temporal analysis of these dynamics using several satellite sources can reveal erosion and deposition patterns which becomes especially relevant in the context of climate change and sea level rise. All coastal engineering, planning and management actions require an understanding of the type of shoreline, its stability and dynamics. EOMAP provides shoreline type and stability classifications as well as change monitoring of shoreline dynamics, highlighting accretion and erosion. We base the analysis on different satellite sources such as the Copernicus Sentinel-2 or DigitalGlobe’s WorldView satellites, resulting in an increased mapping frequency and a more detailed view on shoreline processes. The derivation of shorelines from satellite data is performed by deriving spectral thresholds for polygon and polyline creation. Subsequently, gain and loss calculations are conducted to highlight areas of erosion and accretion.
