The Coastal Overview data layers identifies the lead authority for the management of discrete stretches of the English coast as defined by the Seaward of the Schedule 4 boundary of the Coastal Protection Act 1949. The data are intended as a reference for GIS users and Coastal Engineers with GIS capability to identify the responsible authority or whether the coast is privately owned. The information has been assigned from the following sources, listed in by preference: Shoreline Management Plans 1; Environment Agency’s RACE database; Consultation with Coastal Business User Group and Local Authority Maritime records where possible. A confidence rating is attributed based on where the data has been attributed from and the entry derived from the source data. The following data is intended as a reference document for GIS users and Coastal Engineers with GIS capability to identify the responsible authority and the assigned EA Coastal Engineer so as to effectively manage the coast for erosion and flooding. The product comprises 3 GIS layers that are based on the OS MasterMap Mean High Watermark and consists of the following data layers that are intended to be displayed as with the confidence factor that the information is correct. Coastal Overview Map [Polyline] –details the Lead Authority, EA Contact and other overview information for coast sections; Coastal Overview Map [Point] – shows the start point of the discrete stretch of coast and the lead authority; and Coastal Legislative Layer [Polyline] - represents the predominant risk; flooding or erosion, which are assigned to each section of the coastline.

This data is sourced via WMS from the Channel Coastal Observatory - National Network of Regional Coastal Monitoring Programmes of England.The Network comprises 6 Regional Programmes, collecting coastal monitoring data in a co-ordinated and systematic manner to serve the needs of coastal engineering and management.Please visit the Network's website for more details and to download the data.

The National Coastal Erosion Risk Map shows projected areas at risk from erosion. The erosion risk zones are created by splitting the coastline into ‘frontages’. These frontages are defined as lengths of coast with consistent characteristics based on location, the cliff behaviour characteristics and the defence characteristics.

It is intended as an up-to-date and reliable benchmark dataset showing erosion risk extents for:

Two periods: Medium Term (up to 2055) and Long Term (up to 2105)

Two management scenarios: With Shoreline Management Plans delivered and No Future Intervention

Three climate scenarios: Present Day climate (2020), Higher Central allowance and Upper End allowance. The two allowances use sea level rise data from UKCP18 RCP8.5 70th and 95th percentiles respectively.

Defence type and SMP policies for each of the two periods described above are included. All distances are cumulative over time and given in metres.

Ground instability zones show areas of geologically complex cliffs where land has previously experienced ground movement. This zone uses the rear scarp position as the landward extent. A buffer zone identified as having the potential risk of future movement in the next 100 years is also included.

INFORMATION WARNINGS:

The data and associated information are intended for guidance only - it cannot provide details for individual properties.

The data shows areas of land likely to be at erosion risk but does not show the precise future position of the shoreline.

The information is provided as best estimates based upon historic data termed ‘present day’ and, the higher central and upper end sea level rise climate change allowances representing UKCP18 RCP8.5 sea level rise projections. Unlike the previous NCERM, data ranges based on percentiles are not provided.

The NCERM information considers the predominant risk at the coast, although flooding and erosion processes are often linked, and data on erosion of foreshore features are, in general, not included.

Some parts of the coast have complex geology causing ground instability. Unlike the previous NCERM, data on these zones of ground instability are provided. More detailed information on these areas may be available from local authorities.

The Marine Maps and Chart Archive held by BGS contains maps created by BGS (the majority of which result from BGS offshore mapping projects) and also maps acquired from various other sources (e.g. UK Hydrographic Office and MCA Civil Hydrography Programme survey charts). The maps which date from the 1960s onwards are very variable in subject type and scale ranging from survey navigation to geological interpretation. The maps are primarily for the UKCS (United Kingdom Continental Shelf). The coverage of some map types is the entire UKCS whilst other have only regional or localised extent. The maps which are a mix of paper and digital are applicable to a wide range of uses including environmental, geotechnical, geophysical and geological studies. range of uses including environmental, geotechnical, geophysical and geological studies. Scanned maps can be viewed via the BGS maps portal http://www.bgs.ac.uk/data/maps.

This is a 1:10,000 scale Bedrock geological map for some 800 km2 of the seabed across Weymouth Bay in Dorset. It joins seamlessly to the onshore BGS 1:10,000 scale Digital Geological Mapping (DiGMapGB-10) and therefore shows the coastal geology in detail. It comprises bedrock polygons, faults and limestone bed lines. The map was produced in 2015-16 by digitising against a seamless on- to offshore-shore elevation surface generated from high (1 m bin) resolution bathymetry and coastal Lidar data, collected as part of the Dorset Integrated Seabed Survey (DORIS) project and the Regional Coastal Monitoring Programme of England, made available by the Channel Coastal Observatory under the Open Government Licence. The map can be veiwed using the map viewer at www.bgs.ac.uk/research/marine/doris.html.

The purpose of this digital dataset is to provide accurate mapping of the distribution of sea-bed sediment types. Sea-bed sediments can only be mapped offshore, where the most recent deposits commonly form a veneer or superficial layer of unconsolidated material on the sea-bed. The dataset is produced for use at 1:250,000 scale. The boundaries between sediment classifications or types are delineated using sample station particle size analyses and descriptions, seafloor topography derived from shallow geophysical data and where available multibeam bathymetry and backscatter and side scan sonar profiles. The sediment types present on the sea-bed are of importance to a range of groups, including marine habitat mappers, marine spatial planners, the offshore construction and development sector, and the dredging and aggregate industries. These groups require detailed information on the nature of the sea-bed, including the sediment types present. The DiGSBS250k dataset has been created as vector polygons and are available in a range of GIS formats, including ArcGIS (.shp), ArcInfo Coverages and MapInfo (.tab). More specialised formats may be available but may incur additional processing costs.

This record is for Approval for Access product AfA196. This dataset identifies which second generation Shoreline Management Plan is applicable to a particular stretch of coastline. It also identifies the policies which are applicable. It is a polyline, spatial data layer. A Shoreline Management Plan (SMP) is a large-scale assessment of the risks associated with coastal processes and helps reduce these risks to people and the developed, historic and natural environments. Coastal processes include tidal patterns, wave height, wave direction and the movement of beach and seabed materials. The SMPs provide a ‘route map’ for local authorities and other decision makers to move from the present situation towards meeting our future needs, and will identify the most sustainable approaches to managing the risks to the coast in the short term (0-20 years), medium term (20-50 years) and long term (50-100 years). INFORMATION WARNING This dataset was created for the purposes of creating a strategic overview map; as a consequence it was created at a notional scale of 1:250,000, this means that the definition of the breakpoints and the accuracy to which the SMP lengths reflect the 'coastline' is suitable for strategic level use only. Consideration should be given as to whether it should be replaced by a more accurate representation. More detailed representations of the SMP boundaries may be available at Local/Regional level. Costing information is at a broad scale and indicative only. It not appropriate for any detailed costings work, or for identifying planned capital expenditure.

Interactive map service (http://ims.sea.gov.ua:8081/website/Atlas_forAll_en/viewer.htm), based on GIS database ATLAS has been created by UkrSCES to provide an integrated picture of the modern state of the Black Sea coastal zone. It provides information on the geography of NWBS coastal zone and coastal water areas, as well as data on demography, natural resources, economy and pollution. The work is financed under the auspices of the Ministry for Environmental Protection of Ukraine. ATLAS is organised around several themes and elements, comprising interactive maps, statistical data, and descriptions. The cartography is based on the digital topographic chart of Ukraine (scale 1:500,000) and includes the following thematic layers: * Natural resources, * Protected territories, * Pollution resources, * Recreational potential, * Coastal zone. The main part of the descriptive text of ATLAS is drawn from the results of various studies that were undertaken by UkrSCES from 1993 to 2006. ATLAS allows users to select and display information on the resources, state and condition оf the NWBS coastal zone. This interactive service can be employed not only by experts and those responsible for decision-making, but also by the general public. It represents a major contribution to Ukraine's responsibilities under the Aarhus Convention for access to environmental information.

Introduction

The Strategic Flood Map (Coastal) map service is a multi layered predictive flood mapping product providing a strategic overview of areas across Northern Ireland that could be affected by coastal (or sea) flooding. The Strategic Flood Map (Coastal) includes the following layers of information for both present day and climate change epochs: • Floods with a medium probability

Purpose of the data The dataset has been designed to raise awareness among the public, Government Departments, local authorities and other organisations of the likelihood of coastal flooding, thus supporting a more proactive and co-operative approach to flood risk management. By being aware of the land estimated to be at risk of flooding, authorities can develop strategies to better manage flood risk through their planning, flood prevention, and emergency planning functions.

Data Coverage Around the coast of Northern Ireland.

Data Format

OGC (Open Geospatial Consortium) compliant Web Mapping Service in WGS 1984 projection, accessible via secure website (requires authentication by user specific username and password).

Data content

Extreme Sea Level Strategic Coastal Floodplain o Coastline Strategic Coastal Floodplain (Present Day) o Medium Probability Floods (0.5% AEP) Strategic Coastal Floodplain (Climate Change 2030) o Medium Probability Floods (0.5% AEP)

AEP is Annual Exceedance Probability e.g. the 0.5% AEP flood extent shows areas of land with an annual probability of flooding of 0.5% (or 1 in 200 chance) in any year.

With the historic maps in the Geography Visualiser we can make comparisons of the coastline between 1900, the 1940's and present day.This video will show you how.

The data shows the location of seabed and sub-seabed samples collected from the UK continental shelf, held by BGS. A BGS Sample Station is a general location at which sampling with one or more equipment types, such as borehole, grab, dredge, has been used. Historically, all deployment of equipment was recorded with the same coordinates so the data shown here will often show several sets of data at the same location. Newer data will begin to show distinct locations based on an equipment type. This layer shows all the BGS Sample Station Locations, including those where the Sampling was unsuccessful. The layers below are divided into distinct equipment types, plus a separate layer for unsuccessful sampling. BGS Sample Station Locations can have a wide range of potential information available. This can vary from a basic description derived from a simple piece of paper up to a complex set of information with a number of datasets. These datasets can include particle size analysis, geotechnical parameters, detailed marine geology, geochemical analysis and others. Prices are available on further enquiry.

The Marine Hard Substrate dataset maps areas of rock or hard substrate outcropping or within 0.5m of the sea-bed. The interpretation was based on a variety of data sourced from within the British Geological Survey and externally. Data consulted includes archive sample and seismic records, side scan sonar, multibeam bathymetry and Olex datasets. The distribution of hard substrate at the seabed, or within 0.5 m is important in dictating the benthic assemblages found in certain areas. Therefore, an understanding of the distribution of these substrates is of primary importance in marine planning and designation of Marine Conservation Zones (MCZs) under the Marine and Coastal Access Act, 2009. In addition, a number of other users will value these data, including marine renewable companies, aggregate companies, the fishing and oil and gas industries. In order to address this issue it was necessary to update British Geological Survey sea-bed mapping to delineate areas where rock, boulders or cobbles are present at, or within 0.5m of the sea-bed surface. A polygon shape file showing areas of rock or hard substrate at, or within 0.5m of the sea-bed has been developed. The dataset has been created as vector polygons and are available in a range of GIS formats, including ArcGIS (.shp), ArcInfo Coverages and MapInfo (.tab). More specialised formats may be available but may incur additional processing costs.

PLEASE NOTE: This dataset has been retired. It has been superseded by https://environment.data.gov.uk/dataset/04532375-a198-476e-985e-0579a0a11b47.The Flood Map for Planning (Rivers and Sea) includes several layers of information. This dataset covers Flood Zone 2 and should not be used without Flood Zone 3. It is our best estimate of the areas of land at risk of flooding, when the presence of flood defences are ignored and covers land between Zone 3 and the extent of the flooding from rivers or the sea with a 1 in 1000 (0.1%) chance of flooding each year. This dataset also includes those areas defined in Flood Zone 3.This dataset is designed to support flood risk assessments in line with Planning Practice Guidance ; and raise awareness of the likelihood of flooding to encourage people living and working in areas prone to flooding to find out more and take appropriate action.The information provided is largely based on modelled data and is therefore indicative rather than specific. Locations may also be at risk from other sources of flooding, such as high groundwater levels, overland run off from heavy rain, or failure of infrastructure such as sewers and storm drains.The information indicates the flood risk to areas of land and is not sufficiently detailed to show whether an individual property is at risk of flooding, therefore properties may not always face the same chance of flooding as the areas that surround them. This is because we do not hold details about properties and their floor levels. Information on flood depth, speed or volume of flow is not included.NOTE: We have paused quarterly updates of this dataset. Please visit the “Pause to Updates of Flood Risk Maps” announcement on our support pages for further information. We will provide notifications on the Flood Map for Planning website to indicate where we have new flood risk information. Other data related to the Flood Map for Planning will continue to be updated, including data relating to flood history, flood defences, and water storage areas.

The Sussex coast was mapped during several visits to the area using AGDS, and drop down video. On interest was the location of reef areas and chalk outcrops thoughout the area in addtion to general biological mapping for conservation.

The Geological Survey of Northern Ireland (GSNI) was commissioned to produce a Northern Ireland wide coastal geological dataset, detailing the bedrock geology.GSNI used the 1;10,000 digital bedrock geology map to create a coastal dataset which extends inland 200 meters and out to a seaward depth of approx. 10 metres, matching the extend of the Northern Ireland 3-Dimensional Coastal Survey. This involved refinement of the existing 1;10,000 map where signification coastal change has occurred since the original survey. Where gaps existed, unpublished datasets were used.

The following probabilities are available for coastal flooding: High - 10 year return period, Medium - 200 year return period, Low - 1000 year return period and 200 year return period plus climate change.For most of Scotland, the climate change scenario used the UK Climate Projections 2009 (UKCP09) high emissions 95th percentile relative sea level rise projections for the year 2080. For the Outer Hebrides, UK Climate Projections 2018 (UKCP18) Representative Concentration Pathway 8.5 (RCP8.5) 95th percentile relative sea level rise projections for the year 2100 were used.The coastal flood hazard maps show (where available): Flood extent, flood depth.

The Flood Map for Planning (Rivers and Sea) includes several layers of information. This layer and documentation covers Flood Zone 2. It is the Environment Agency's best estimate of the areas of land at risk of flooding, when he presence of flood defences are ignored and covers land between Zone 3 and the extent of the flooding from rivers or the sea with a 1 in 1000 (0.1%) chance of flooding each year. This dataset also includes those areas defined in Flood Zone 3.This dataset is designed to support flood risk assessments in line with Planning Practice Guidance ; and raise awareness of the likelihood of flooding to encourage people living and working in areas prone to flooding to find out more and take appropriate action. This dataset is republished by the West of England Combined Authority for supplementing information within our Local Nature Recovery Strategy. If you are using it for statutory purposes, you should refer to the Environment Agency's canonical version, linked in the Attributions field below as this is likely to be more current.

This is a digital version of the paper based 1:1M scale Offshore Quaternary map, North and South sheets. Customers should be aware that, given the age of the paper based maps, the digital version is not quality assured and BGS can accept no liability for the information held on the digital map. In addition, published 1:250,000 Quaternary maps are available. These contain more detailed subdivision of the Quaternary succession. The original paper based map covers the UK Continental shelf. The paper map is symbolised using lithology and chronology. The lithological boundaries were compiled from the data published in the BGS 1:250,000 Quaternary Geology map series and from revised interpretation of core and borehole data. Core and borehole sites are commonly 5 to 20 km apart, thus the lithological divisions are generalised. The formations and sequences identified by BGS have been grouped into Quaternary age ranges. The geological codes assigned to the digital version of the map have been compiled using the key information held on the paper map. The LEX-ROCK style codes combine the lithology and chronology and have been subject to the standard BGS approval process.
