Statement

This dataset has been produced following a five steps process; 1) ensuring that all suitable satellite images are collected using an innovative bespoke filtering method; 2) geolocation of each single satellite image to high resolution 25 cm geolocated aerial imagery; 3) co-registration of the geolocated satellite images from the newest (2022) to the oldest (1984); generation of vector waterlines per satellite image using adaptive thresholding to maximize the signal to noise ratio, the marching squares algorithm for interpixel line delineation and graded the waterlines on structural properties for quality control ensuring that only high confidence waterlines are passed through the shoreline processor and final step; 5) waterlines are converted into theoretical shorelines using auxiliary data collected on slope, tide height, mean sea level height and the sea bearing at the sensing time.
