They are provided as attributed 50 m grid cells around the coastline of Great Britain. The data has been developed from BGS databases and datasets, regional expertise and additional analytics to compile the essential baseline geo-information necessary to feed into coastal vulnerability analyses and assessments for resilience and adaptation. GeoCoast Premium consists of: • coast grid dataset -Foreshore (type; properties; spatial area) -backshore (type; properties; spatial area) -coastal erosion susceptibility overview (vertical cliff layers; properties) -cliff profiling (slope angle; distance; cliff height) -potential inundation zones under climate change scenarios (future sea level rise forecast for 2050, 2080 and 2100) -coastal subsidence potential (satellite measurements and lithology type) • groundwater flooding and coastal flood dataset (combined hazards indicating exacerbated impact) • coastal erosion susceptibility dataset (a full lithology by lithology detailed attributes) The BGS GeoCoast dataset is a Geographic Information System (GIS)-based analysis for indicating multi-hazards and interdependencies within the coastal zone of Great Britain (not including Orkney and Shetland). GeoCoast represents the natural geological coastline (around the mainland of Great Britain) as if no coastal defences or made ground are present. This will be of particular value in areas where coastal defences are no longer maintained. GeoCoast will offer anyone with assets, or an interest in the coastline around Great Britain, access to easy-to-use datasets linked to geohazard data. This will allow users to interpret potential interdependencies in terms of erosion, flooding, habitat and other vulnerabilities.

The final gridded output is designed to streamline the multiple key datasets and potential factors that impact on coastal processes. Rather than having multiple layers, the data will be combined to create an easy-to-use dataset that contains all of the relevant data necessary for a coastal assessment. The gridded format (50 m grid cells) also helps to convey to users the accuracy limitations of the data rather than having a specific vector line that users often perceive as a precise location, particularly where shorelines are concerned. These include the following information: GeoCoast Premium: Coastal Properties Grid • Foreshore (type, properties, spatial area): the area between high water line and low water line. • Backshore (type, properties, spatial area): the area between high water line and the landward limit of coastal deposits. • Coastal erosion susceptibility (vertical cliff layers, properties): erosion scores ranking from 0 (low susceptibility to erosion) – 100 (high susceptibility to erosion) and divided into 5 susceptibility classes. Data available for every lithology within in cliff section plus summary data for mean, worst-case and lithology 1 (base lithology). • Cliff profiling (slope angle/distance/cliff height): based from high water line to top of cliff section as defined by transects across a Digital Terrain Model (DTM). • Inundation under climate change scenarios (future sea level rise, 2020 (baseline), 2050, 2080, 2100): max flood extents as defined by UKCP18 sea level rise climate scenarios. • Coastal subsidence potential (satellite measurements and lithology type): based on geology properties and measured subsidence from satellite. • Groundwater flooding zones: A combined assessment of coastal inundation (not including UKCP18 scenarios) and groundwater flooding susceptibility to identify areas where combined hazards have the potential to exacerbate impact.
