Title

Digital Great Britain coastlines (DiGBcoast v1.0): a dataset of the coastline position of Great Britain from 1984 to 2022 derived from publicly available optical satellite imagery

Abstract

DiGBcoast v1.0, is a new supranational dataset documenting three decades of coastal change across Great Britain mainland (England, Scotland, and Wales) including the isle of Wight and Anglesey. This dataset has been produced using the publicly available optical Landsat-5,8 and Sentinel-2 missions over the period between 1984 to 2022 (38 years). It includes instantaneous waterlines and instantaneous tidally corrected to Mean Sea Level shorelines. DiGBcoast is made available to the public as free and open interactive data to support future coastal research and management across Great Britain.

Quality and validity

Lineage

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.
