Dataset of Annual Shoreline Positions of England and Wales (1999–2020)

This dataset contains annual shoreline positions for England and Wales covering the period from 1999 to 2020. The entire coastline has been divided into 276 Regions of Interest (ROIs). For each ROI, coastline positions are provided in both tabular and GeoJSON formats. Coastlines were extracted for each ROI, but validation was performed only for sandy beaches. The dataset includes coastlines for all ROIs, covering both sandy and other types of beaches. The dataset includes the following components: 1. ROI ClassificationA file containing the classification of each ROI as either a sandy beach or another type of coastline. 2. TransectsA directory containing all transects for each ROI, used in the coastline extraction process for tidal correction. These files are provided in GeoJSON format and can be directly imported into mapping platforms. 3. Coastline PositionA directory containing coastline position data in two formats: GeoJSON: Coastline positions for each ROI in GeoJSON format, ready for direct import into mapping platforms. Table: Coastline positions stored as latitude and longitude coordinates for each ROI. The data is presented in tabular form, with transects as columns and dates as rows.
