UKCS offshore petroleum licences (WGS84)

A Licence is a geographically defined area for prospecting, exploration or extraction of petroleum resources. The North Sea Transition Authority's licensing system covers oil and gas within Great Britain, its territorial sea and on the UK Continental Shelf (UKCS). The Petroleum Act 1998 vests all rights to the nation's petroleum resources in the Crown, but the NSTA can grant licences that confer exclusive rights to 'search and bore for and get' petroleum. Licences fall into several categories. The principal distinctions are between onshore and offshore licences, and between exploration licences (which cover exploration alone) and production licences (which cover both exploration and production). The NSTA has discretion in the granting of licences to help maximise the economic recovery of the UK's oil and gas resources. Licence data is represented by 3 different datasets; Licences, Licence Blocks and Sub Areas. Licence polygons represent the whole licence and have one polygon per licence. Licenced Blocks and Sub areas represent finer divisions of these licences and may have many polygons per licence. Most Licenced Blocks are split with several sub areas, sometimes with differing operators and beneficiaries.
UKCS offshore wellbores top holes (WGS84)

A wellbore is a path of drilled footage from the Well Origin to a terminating point. The location of each wellbore is the wellbore's well origin. A well origin is the location on the surface of the earth or sea bed where the drill bit penetrates the earth to establish or rework a well. Definitions for wellbore and well origin taken from PPDM â€˜what is a well': https://whatisawell.ppdm.org/. Data collection starts once a well has been spudded when the operator submits a spud notification on WONS. The NSTA will issue an official well number via WONS, which is to be used for all data and records resulting from the well's drilling. All well data requirements are set out in the documents Petroleum Operations Notices (PON) 9 (offshore) and PON 9b (onshore). Onshore operators have a statutory obligation to also supply well data to the British Geological Survey (BGS). Visit the BGS website for more information. Wellbore Bottom Hole is the bottom hole location of the borehole at its final measured total depth. Top Hole - Bottom Hole, Straight Line Connection is a straight line connection from the top hole location and bottom hole location, it is not a wellbore path.
OS Open Greenspace

OS Open Greenspace depicts the location and extent of spaces such as parks and sports facilities that are likely to be accessible to the public. Where appropriate, it also includes access points to show how people get into these sites. Open Greenspace consists of the following classifications: * Public parks or gardens * Play spaces * Golf courses * Sports areas or playing fields * Churchyards or burial grounds * Allotments or community growing spaces Its primary purpose is to enable members of the public to find and access green spaces near them for exercise and recreation. Find out more about the uses and case studies surrounding Greenspace on the dedicated OS Open Greenspace webpage, and technical information about the greenspaces it contains and how to use them in our detailed specification. Who's using OS Open Greenspace? * Innovators - Britain’s most comprehensive Open dataset of greenspaces underpins a range of apps, products and innovations - providing the foundation to help create greener and healthier communities. * Public sector (Public Health England) - Incorporated as a layer into SHAPE, the dataset has been used alongside asset location data (GPs, pharmacies, schools) and indicator data (population and deprivation), to help inform and support the strategic planning of services and physical assets across the health economy. * Emergency services - A vital tool in helping our emergency services, OS Open Greenspace includes site use and access points, making it quicker to get to emergency situations. The currency of the data is April 2026 and has a six-monthly update cycle (April and October). This data has been sourced from the OS and Esri UK claim no ownership of the data.

Conservation Areas

Conservation areas exist to manage and protect the special architectural and historic interest of a place - in other words, the features that make it unique. Every local authority in England has at least one conservation area and there are around 10,000 in England.Most conservation areas are designated by the Council as the local planning authority. In conservation areas there are some extra planning controls and considerations in place to protect the historic and architectural elements which make the place special. This national dataset is “indicative” not “definitive”. Definitive information can only be provided by individual local authorities and you should refer directly to their information for all purposes that require the most up to date and complete dataset. Conservation area data has not been supplied for all local authority areas. Local authority areas without conservation area data are attributed with 'No data available for publication by HE'. Data is updated as necessary when new data is received.

RSPB Priority Landscapes

RSPB Priority Landscapes Dataset created in 2018. Last updated 18 June 2026. Digitised in Merlin from Ordnance Survey Mapping. Priority landscapes were developed with the aim of protecting, restoring and recreating large areas of well-functioning priority habitats. This has ecological, habitat connectivity and land management benefits. Within these areas the RSPB will deploy the best combination of our conservation ‘tool-kit’ available, to effectively deliver enhanced land management for habitat and species outcomes. Landscape areas were selected, based on: * Ecological importance * Clarity of plan/roadmap * Achievability/impact * Capabilities * Presence of existing initiatives The Landscape Areas have been developed collaboratively with operational teams supported by UK level oversight. A key identifying each landscape area is associated with this map.
WWT combined 'multi-benefit' wetland potential

This dataset combines the WWT ['wetlands for water quality'], ['wetlands for blue carbon'], ['wetlands for flood resilience'] and ['wetlands for urban wellbeing'] layers, and indicates where these four layers overlap. The greater the number of overlapping wetland potential layers, the greater the potential to create wetlands that provide multiple key benefits to society. While most wetlands support a range of ecosystem services, these locations indicate where return on investment could be particularly high. This wetland potential map is not prescriptive at the site level and does not replace the need for detailed site selection processes, feasibility studies, and regulatory processes. The intention is to illustrate the overall potential and to direct users’ thoughts in a strategic way, rather than precisely telling them where to put wetlands, or specifying where action should or will necessarily take place. WWT are calling for the creation of 100,000 hectares of new and restored wetlands in the UK by 2050. This map is a part of [WWT’s Roadmap to 100,000 hectares project], which aims to assess both the spatial and economic potential for large-scale wetland restoration targeted at tackling some of the key issues faced by UK society. The work has a particular focus on four themes where wetlands can provide solutions, namely (1) wetlands for carbon storage (specifically saltmarsh for blue carbon), (2) wetlands for urban wellbeing, (3) wetlands for flood resilience, and (4) wetlands for water quality. Wetland potential for [water quality], [carbon storage], [flood resilience] and [urban wellbeing] has been mapped. Full methodology can be found [here].

Census 2021 Health, Disability and Unpaid Care Disability - TS038

Office for National Statistics' national and subnational Census 2021. Disability This dataset provides Census 2021 estimates that classify usual residents in England and Wales by long-term health problems or disabilities. The estimates are as at Census Day, 21 March 2021. Disability definition: People who assessed their day-to-day activities as limited by long-term physical or mental health conditions or illnesses are considered disabled. This definition of a disabled person meets the harmonised standard for measuring disability and is in line with the Equality Act (2010). Comparability with 2011: Broadly comparable The question related to this variable was split into two parts for Census 2021. In Census 2021 we asked people completing the questionnaire if they have any physical or mental health conditions or illnesses. In the 2011 Census, people were asked if they have a health problem or disability. We also removed the option to include information about problems related to old age. This data is issued at [(BGC) Generalised (20m)] boundary type for: * Country - England and Wales * Region - England * UTLA - England and Wales * LTLA - England and Wales * Ward - England and Wales * MSOA - England and Wales * LSOA - England and Wales * OA - England and Wales If you require the data at full resolution boundaries, or if you are interested in the range of statistical data that Esri UK make available in ArcGIS Online please enquire at content@esriuk.com.

Big River Watch (UK and Ireland)

This September, we all came together for rivers to take part in our first Big River Watch Weekend, launched to help build a picture of river health across the country. It's good for you, and good for our rivers. This mapping layer allows you to view the results submitted by our citizen science volunteers. Whether you’re a swimmer or a paddler, an angler or a rambler, a wildlife spotter or a sit-and-watch-er, Big River Watch is a chance to be part of the movement improving our freshwater spaces. In just three easy steps, you can contribute to a national data set that will help us build a picture of river health across the UK and Ireland. Since September 2023 Big River Watch has been held twice a year, in the spring and autumn. With your help, we are building a picture of rivers in the UK and Ireland over time from the perspective of citizen scientists. How can you contribute? Step 1: Sign up Sign up and download the survey app to your phone before visiting your chosen river. Step 2: Take part Pick a riverside location and spend just 15 minutes observing and answering the questions on the survey. You can complete the survey at your favourite local spot, or choose to get to know somewhere new. Step 3: Upload Upload your survey. It's that simple to get involved! Intended use: Data gathered can support policy change; helping turn the tide on plastics or stem the flow of untreated sewage that reaches our waterways. It also helps identify the best places for river clean-ups, and spots to install things like leaky dams which slow the flow, boost biodiversity and reduce flood risk.

Terrain - Slope Map

This map provides a colorized representation of slope, generated dynamically using server-side slope function on the [Terrain layer]. The degree of slope steepness is depicted by light to dark colors - flat surfaces as gray, shallow slopes as light yellow, moderate slopes as light orange and steep slopes as red-brown. A scaling is applied to slope values to generate appropriate visualization at each map scale. This service should only be used for visualization, such as a base layer in applications or maps. Note: If access to non-scaled slope values is required, use the [Slope Degrees] or [Slope Percent] functions, which return values from 0 to 90 degrees, or 0 to 1000%, respectively. Units: Degrees Update Frequency: Quarterly Coverage: World/Global Data Sources: This layer is compiled from a variety of best available sources from several data providers. To see the coverage and extents of various datasets comprising this service in an interactive map, see [World Elevation Coverage Map]. What can you do with this layer? Use for Visualization: Yes. This colorized slope is appropriate for visualizing the steepness of the terrain at all map scales. This layer can be added to applications or maps to enhance contextual understanding. Use for Analysis: No. 8 bit color values returned by this service represent scaled slope values. For analysis with non-scaled values, use the [Slope Degrees] or [Slope Percent] functions. For more details such as Data Sources, Mosaic method used in this layer, please see the [Terrain layer]. This layer allows query, identify, and export image requests. The layer is restricted to a 5,000 x 5,000 pixel limit in a single export image request. This layer is part of a larger collection of [elevation layers] that you can use to perform a variety of mapping and analysis tasks.
Consented Discharges to Controlled Waters (England)

This data was extracted from the Environment Agency’s Public Register in March 2026 and republished by The Rivers Trust. CaBA identifiers were added using a spatial join to allow easy filtering. Some fields from the original dataset have been removed. This layer only contains Tier 1 Site and General information for all active permits. Tier 2 and Tier 3 information can be obtained from the full Consented Discharges to Controlled Waters with Conditions database, available from [environment.data.gov.uk]. You can also access the Public register information through the [Defra API portal]. These data provide all permit details as required under the Environmental Permit Regulation. Information is held for all permit holders and covers all substances that are controlled. More details on the information available in each tier: * Tier 1 – Site and General Information on the consent holder that has a consent to discharge into controlled waters. Consent holder and the discharge address and type. The date of permit issue, effective and revocation. Information where the effluent enters the environment (such as sewage disposal works) for each holder that has been granted a permit. Data is also held on the effluent type e.g. Sewage effluent, Overflow. The location of the grid reference is supplied for the effluent and the outlet location in OS Nation Grid Reference format. * Tier 2 – Effluent Further detail is provided on the amount that can be discharged and in which time period in months. This is stored as Dry Weather Flow, Maximum Daily, Mean, Maximum Rate. Further data about the permit type and treatment type from lookup lists are provided. * Tier 3 – Determinand Limits Determinands are the substances and numerical limits that make up the effluent. This could include chemical, biological, and physical limits. Textual conditions are not included. The permitted limits are included for each determinand type. Data is provided for each effluent and may contain one or more determinands depending on the complexity of the discharge.

RSPB Reserves

RSPB reserve boundaries. Data Updated (Vintage): 11th June 2026. Note Access field which denotes which reserves have visitor access. The RSPB Public Reserve Boundaries dataset contains the boundaries of all land managed, leased or owned as part of publicly accessible RSPB reserves. Areas for which other rights are held or which are not classed as RSPB reserves are excluded. Some reserves are only represented by an indicative boundary due to confidentiality issues surrounding the definitive boundary. Update frequency: This dataset is updated annually. Limitations: Boundaries for sensitive areas are not included. The reserve boundaries are updated continuously, so this dataset may not respresent the most recent boundaries.

Event Duration Monitoring - Storm Overflows - 2024 (England and Wales)

This Event Duration Monitoring dataset relates to overflow performance in England and Wales. Water and Sewerage Companies (WaSCs) submit this regulatory return annually to the Environment Agency or Natural Resources Wales to meet discharge conditions outlined in the Environmental Permitting Regulations. The English data were downloaded from [environment.data.gov.uk] (accessed 27th March 2025). Sewer Storm Overflow EDM Annual Returns Data for Wales were downloaded from the [Dŵr Cymru/ Welsh Water] and [Hafren Dyfrdwy] websites. For England, the dataset also includes reasons why event duration monitors may have provided information for <90% of the relevant return period, and why an overflow may have high spill counts in that period. What doesn't this dataset show? There are a significant but unknown number of overflows which are not included in this dataset because the WASCs and the Environment Agency don't know where they are within the sewer network. If you spot signs of sewage pollution please report this to the Environment Agency on [0800 80 70 60] or Natural Resources Wales on [0300 065 3000] so that these unmapped discharges can be pinpointed. Emergency overflows in England and Wales are not included in this dataset as the Environment Agency and Natural Resources Wales only require storm overflows to be included in the EDM returns, though some WASCs do record this information. Emergency overflows do have permits but these are for use in the event of mechanical issues, for example pump failure. We do publish the emergency overflows for England and Wales in the [consented discharges dataset], but we don't have spill duration data for them. You can find out more about environmental permits for storm and emergency overflows for England [here] and Wales [here]. Quality Control The Rivers Trust has endeavoured to clean, check and interpret the data, but cannot be held responsible for any missing or inaccurate data. Points in the sea may be long-sea outfalls or they may be errors in the data. Water companies, citizen scientists and map users are welcome to [contact us] to notify any known data errors on specific overflows and we will flag these in the map popups and pass on to the regulators. We are providing feedback to the Defra storm overflows taskforce about how to improve transparency around sewer storm overflows, and would welcome feedback and suggestions.
