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.

The Historic Flood Map is a GIS layer showing the maximum extent of individual Recorded Flood Outlines from river, the sea and groundwater springs that meet a set criteria. It shows areas of land that have previously been subject to flooding in England. This excludes flooding from surface water, except in areas where it is impossible to determine whether the source is fluvial or surface water but the dominant source is fluvial.
The majority of records began in 1946 when predecessor bodies to the Environment Agency started collecting detailed information about flooding incidents, although we hold limited details about flooding incidents prior to this date.
If an area is not covered by the Historic Flood Map it does not mean that the area has never flooded, only that we do not currently have records of flooding in this area that meet the criteria for inclusion. It is also possible that the pattern of flooding in this area has changed and that this area would now flood or not flood under different circumstances. Outlines that don’t meet this criteria are stored in the Recorded Flood Outlines dataset.
The Historic Flood Map takes into account the presence of defences, structures, and other infrastructure where they existed at the time of flooding. It will include flood extents that may have been affected by overtopping, breaches or blockages.
Flooding is shown to the land and does not necessarily indicate that properties were flooded internally.
This dataset is now retired and replaced with the following:
Reservoir Flood Extents - Fluvial Contribution (National) https://environment.data.gov.uk/dataset/db114020-465a-412b-b289-be393d995a75 Reservoir Flood Extents - Wet Day (National) https://environment.data.gov.uk/dataset/d81646cf-37e5-4e71-bbcf-b7d5b9ca3a1c Reservoir Flood Extents - Dry Day (National) https://environment.data.gov.uk/dataset/c66ee97f-49d2-454e-9a19-d48a47bd22ad
This is the simplified version of the outline Reservoir Flood Map Outline (Speed) as shown on the gov.uk Flood Risk website. This is one of 3 available "Risk of Flooding from Reservoirs" Web Mapping Services; Maximum Flood Depth, Maximum Flood Extent, Maximum Flood Speed.
. Simplified in this context refers to the fact that unlike the detailed product, individual reservoir flood map speeds are not shown separately, and one merged outline shows the maximum flood speeds for all reservoir flooding scenarios together.
This is a data layer showing a combined reservoir flood map for 2,092 Large Raised Reservoirs including attributed data. The data shows the maximum speed of flooding should reservoirs be breached, and although the location of each reservoir can be inferred they are not explicitly shown on the maps. The Reservoir Flood Map Maximum Flood Outline (Speed) in its simplified form is referred to externally as Risk of Flooding from Reservoirs – Maximum Flood Speed.
The Reservoir Flood Map Outline (Speed) shows the maximum flood speeds that might be expected if a reservoir were to fail and release the water it holds. Since this is a prediction of a credible worst case scenario, it’s unlikely that any actual flooding would create speeds this high. These data are intended for emergency planning only and are not reliable for large scale flood risk assessments.
Please note that only flood maps for large reservoirs are displayed. Flood maps are not displayed for smaller reservoirs or for reservoirs commissioned after reservoir mapping began in spring 2009.

Recorded Flood Outlines is a GIS layer which shows all our records of historic flooding from rivers, the sea, groundwater and surface water. Each individual Recorded Flood Outline contains a consistent list of information about the recorded flood.
Records began in 1946 when predecessor bodies to the Environment Agency started collecting detailed information about flooding incidents, although we may hold limited details about flooding incidents prior to this date.
The absence of coverage by Recorded Flood Outlines for an area does not mean that the area has never flooded, only that we do not currently have records of flooding in this area.
It is also possible that the pattern of flooding in this area has changed and that this area would now flood or not flood under different circumstances.
The Recorded Flood Outlines take into account the presence of defences, structures, and other infrastructure where they existed at the time of flooding. It includes flood extents that may have been affected by overtopping, breaches or blockages.
Any flood extents shown do not necessarily indicate that properties were flooded internally.
A companion dataset Historic Flood Map contains a subset of these Recorded Flood Outlines which satisfy a certain criteria.

The 1885 UK parliamentary constituencies for Ireland were re-created in 2017 as part of a conference paper delivered at the Southern Irish Loyalism in Context conference at Maynooth University. The intial map only included the territory of the Irish Free State and was created by Martin Charlton and Jack Kavanagh. The remaining six counties of Ulster were completed by Eoin McLaughlin in 2018-19, the combined result is a GIS map of all the parliamentary constituecies across the island of Ireland for the period 1885-1918. The map is available in both ESRI Shapefile format and as a GeoPackage (GPKG). The methodology for creating the constituencies is outlined in detail below.
A map showing the outlines of the 1855 – 1918 Constituency boundaries can be found on page 401 of Parliamentary Elections in Ireland, 1801-1922 (Dublin, 1978) by Brian Walker. This forms the basis for the creation of a set of digital boundaries which can then be used in a GIS. The general workflow involves allocating an 1885 Constituency identifier to each of the 309 Electoral Divisions present in the boundaries made available for the 2011 Census of Population data release by CSO. The ED boundaries are available in ‘shapefile’ format (a de facto standard for spatial data transfer). Once a Constituency identifier has been given to each ED, the GIS operation known as ‘dissolve’ is used to remove the boundaries between EDs in the same Constituency. To begin with Walker’s map was scanned at 1200 dots per inch in JPEG form. A scanned map cannot be linked to other spatial data without undergoing a process known as georeferencing. The CSO boundaries are available with spatial coordinates in the Irish National Grid system. The goal of georeferencing is to produce a rectified version of the map together with a world file. Rectification refers to the process of recomputing the pixel positions in the scanned map so that they are oriented with the ING coordinate system; the world file contains the extent in both the east-west and north-south directions of each pixel (in metres) and the coordinates of the most north-westerly pixel in the rectified image.
Georeferencing involves the identification of Ground Control Points – these are locations on the scanned map for which the spatial coordinates in ING are known. The Georeferencing option in ArcGIS 10.4 makes this a reasonably pain free task. For this map 36 GCPs were required for a local spline transformation. The Redistribution of Seats Act 1885 provides the legal basis for the constituencies to be used for future elections in England, Wales, Scotland and Ireland. Part III of the Seventh Schedule of the Act defines the Constituencies in terms of Baronies, Parishes (and part Parishes) and Townlands for Ireland. Part III of the Sixth Schedule provides definitions for the Boroughs of Belfast and Dublin.
The CSO boundary collection also includes a shapefile of Barony boundaries. This makes it possible code a barony in two ways: (i) allocated completely to a Division or (ii) split between two Divisions. For the first type, the code is just the division name, and for the second the code includes both (or more) division names. Allocation of these names to the data in the ED shapefile is accomplished by a spatial join operation. Recoding the areas in the split Baronies is done interactively using the GIS software’s editing option. EDs or groups of EDs can be selected on the screen, and the correct Division code updated in the attribute table. There are a handful of cases where an ED is split between divisions, so a simple ‘majority’ rule was used for the allocation. As the maps are to be used at mainly for displaying data at the national level, a misallocation is unlikely to be noticed. The final set of boundaries was created using the dissolve operation mentioned earlier. There were a dozen ED that had initially escaped being allocated a code, but these were quickly updated. Similarly, a few of the EDs in the split divisions had been overlooked; again updating was painless. This meant that the dissolve had to be run a few more times before all the errors have been corrected.
For the Northern Ireland districts, a slightly different methodology was deployed which involved linking parishes and townlands along side baronies, using open data sources from the OSM Townlands.ie project and OpenData NI.
This dataset is refreshed on a weekly basis from the datasets the team works on daily.Last update date: 27 June 2025.National Highways Operational Highway Boundary (RedLine) maps out the land belonging to the highway for the whole Strategic Road Network (SRN). It comprises two layers; one being the an outline and another showing the registration status / category of land of land that makes up the boundary. Due to the process involved in creating junctions with local highway authority (LHA) roads, land in this dataset may represent LHA highway (owned by National Highways but the responsibility of the LHA to maintain). Surplus land or land held for future projects does not form part of this dataset.The highway boundary is derived from:Ordnance Survey Mastermap Topography,HM Land Registry National Polygon Service (National Highway titles only), andplots researched and digitised during the course of the RedLine Boundary Project.The boundary is split into categories describing the decisions made for particular plots of land. These categories are as follows:Auto-RedLine category is for plots created from an automated process using Ordnance Survey MasterMap Topography as a base. Land is not registered under National Highways' name. For example, but not limited to, unregistered ‘ancient’ highway vested in Highways England, or bridge carrying highways over a rail line.NH Title within RedLine category is for plots created from Land Registry Cadastral parcels whose proprietor is National Highways or a predecessor. Land in this category is within the highway boundary (audited) or meets a certain threshold by the algorithm.NH Title outside RedLine category is for plots created in the same way as above but these areas are thought to be outside the highway boundary. Where the Confidence is Low, land in this category is yet to be audited. Where the Confidence is High, land in this category has been reviewed and audited as outside our operational boundary.National Highways (Technician) Data category is for plots created by National Highways, digitised land parcels relating to highway land that is not registered, not yet registered or un-registerable.Road in Tunnel category, created using tunnel outlines from Ordnance Survey MasterMap Topography data. These represent tunnels on Highways England’s network. Land is not registered under National Highways' name, but land above the tunnel may be in National Highways’ title. Please refer to the definitive land ownership records held at HM Land Registry.The process attribute details how the decision was made for the particular plot of land. These are as follows:Automated category denotes data produced by an automated process. These areas are yet to be audited by the company.Audited category denotes data that has been audited by the company.Technician Data (Awaiting Audit) category denotes data that was created by National Highways but is yet to be audited and confirmed as final.The confidence attribute details how confident you can be in the decision. This attribute is derived from both the decisions made during the building of the underlying automated dataset as well as whether the section has been researched and/or audited by National Highways staff. These are as follows:High category denotes land that has a high probability of being within the RedLine boundary. These areas typically are audited or are features that are close to or on the highway.Moderate category denotes land that is likely to be within the highway boundary but is subject to change once the area has been audited.Low category denotes land that is less likely to be within the highway boundary. These plots typically represent Highways England registered land that the automated process has marked as outside the highway boundary.Please note that this dataset is indicative only.

Sheet Passau shows an interesting section of the geology in the border triangle of Germany, Austria, and the Czech Republic. The northeast corner of the map sheet is occupied by the Moldanubian of the Bohemian Massif. Parts of the Bohemian Forest and the Bavarian Forest are open. The metamorphic rocks of the Moldanubian period (gneiss, diatexite) are increasingly interspersed with Paleozoic plutonites. These are mostly granite (Hauzenberg, Kristall, Haidmühle, Eisgarn, Sulzberg, Steinberg, Dreisessel, Weinsberg, Schärding, Peuerbach granite), while diorite occurs only occasionally. Two major fault zones, Bayerischer Pfahl and Passauer Pfahl, run through the area in a northwest-southeast direction. The Molasse Basin in the foothills of the Alps takes up the largest area in the map section. The debris trough of the Alps is filled with tertiary sediments of freshwater, brackish water and marine molasses. The tertiary is z. T. overlaid by Pleistocene loose sediments such as gravel from meltwater rivers or loess and loess loam. In addition to the legend, which provides information about the age, genesis and petrography of the units shown, a tectonic overview map illustrates the major geological units in the map sheet. In addition, all overburdens caused by loess drifts are listed and described in detail in an overlay scheme. A geological section that crosses the Molasse Basin from south to north provides additional insights into the structure of the subsoil. In the course of the profile, it becomes clear that the tertiary sediment layers continuously lose thickness northward.

The aim of these statistics is to provide the most reliable and consistent possible breakdown of CO2 emissions across the country, using nationally available data sets going back to 2005.
The main data sources are the UK National Atmospheric Emissions Inventory and BEIS’s National Statistics of energy consumption for local authority areas. All emissions included in the national inventory are covered, except aviation, shipping and military transport, for which there is no obvious basis for allocation to local areas.
Publications:
In addition, on the National Atmospheric Emissions Inventory (NAEI) website, http://naei.defra.gov.uk/data/local-authority-co2-map" class="govuk-link">interactive local authority level emissions maps are published on behalf of BEIS. These allow users to zoom in to any UK local authority and see the emissions for the area, and also identify the significant point sources, such as iron and steel plants. It is also possible to filter by different sectors, and view how emissions have changed across the time series.
http://naei.defra.gov.uk/reports/reports?report_id=809" class="govuk-link">Air pollution data are also available on a local authority basis which looks at a number of gases that cause air pollution. Carbon dioxide which is presented in the emissions reports above is also considered an air pollutant. A number of activities contribute to both air pollutant and carbon dioxide emissions. Other activities that contribute to carbon dioxide emissions do not contribute to air pollutant emissions and vice versa.
This is a National Statistics publication and complies with the code of practice for official statistics. Please check our frequently asked questions or email Climatechange.Statistics@beis.gov.uk if you have any questions or comments about the information on this page.
