Our Data

Ancient woodland is identified using presence or absence of woods from old maps, information about the wood's name, shape, internal boundaries, location relative to other features, ground survey, and aerial photography.

This dataset comprises the boundaries of Ancient Woodland sites in Wales.

Areas of Outstanding Natural Beauty (AONBs) are designated areas where protection is afforded to protect and manage the areas for visitors and local residents. This data is updated approximately yearly.

The dataset shows the chance of flooding from rivers and/or the sea, based on cells of 50m. Each cell is allocated one of four flood risk categories, taking into account flood defences and their condition.

Flood Risk Assessment Wales provides a national assessment of risk flooding from Rivers, the Sea and Surface Water and Small Watercourses.

GIS layer giving a suitability rating which represents the scale at which it is generally appropriate to use this information to assess flood risk.

Flood Risk Assessment Wales provides a national assessment of risk flooding from Surface Water and Small Watercourses (replacing RoFRS, dataset).

Flood zones are a best estimate of the areas of land at risk of flooding. Flood zone 3 covers the areas most likely to flood whilst flood zone 2 covers an area that is likely to be at slightly less risk. This data is updated approximately yearly.

Green belts are areas with increased restrictions on planning and development. This data is updated approximately yearly.

An historic landfill is a site where there is no environmental permit in force, but where a landfill is known to have been. This data is updated approximately yearly.

Geographic boundaries of the local authority districts (LADs) of the United Kingdom. This data is updated infrequently.

Listed buildings hold special architectural or historic interest at a national level, and are therefore given legal protections. The data is updated approximately every two weeks.

Lower Layer Super Output Areas (LSOA) are a geographic hierarchy designed to improve the reporting of small area statistics in England and Wales. This data gives the boundaries of the LSOAs as at December 2011.

Geocoding is the process of taking an address or name of a place and converting it into latitude and longitude values. The Mapbox Geocoding API allows you to performs two types of geocoding: forward geocoding and  reverse geocoding.

The Environment Agency National LIDAR Programme aims to provide accurate elevation data at 1m spatial resolution for all of England by the end of 2021. The country has been divided into approximately 230 logical blocks with survey starting in November 2016.

National Parks are run by National Park Authorities for the purpose of conserving and enhancing the natural beauty, wildlife and cultural heritage and to provide opportunities for the understanding and enjoyment of the Park by the public. This data is updated approximately yearly.

Contains 3 licensed, chargeable datasets: National Polygon dataset, Title Descriptor dataset, and Title Number and UPRN Look Up dataset. These datasets are only available as part of the National Polygon Service and you'll need to agree to a licence to use them.

OS Maps API serves pre-rendered raster tiles and is available in two projections; British National Grid for GB data and Web Mercator which is a global coordinate system.

The joint Public Health England (PHE)-BGS Indicative Atlas of Radon in the United Kingdom presents an overview of the results of detailed mapping of radon potential (defined as the estimated percentage of homes in an area above the radon action level). This data is updated infrequently.

Data indicating the level of noise according to the strategic noise mapping of rail sources within areas with a population of at least 100,000 people (agglomerations) and along Network Rail and HS1 traffic routes. LDEN indicates a 24 hour annual average noise level with separate weightings for the evening and night periods. This data is updated infrequently.

The Environmental Noise Directive required the Welsh Government to produce noise maps in 2017. This data package contains all the sound level contours calculated in 2017, in 5-decibel “A-weighted” contour bands. It also contains spatial data on the sources modelled (the major roads and industrial sites in agglomerations). LDEN indicates a 24 hour annual average noise level with separate weightings for the evening and night periods. This data is updated infrequently.

A Ramsar site is the land listed as a Wetland of International Importance under the Convention on Wetlands of International Importance Especially as Waterfowl Habitat (the Ramsar Convention) 1973. The data is updated approximately yearly and does not include 'proposed' sites.

This data provides detailed road safety data about the circumstances of personal injury road accidents in GB from 1979, the types of vehicles involved and the consequential casualties. This data is updated yearly.

GIS spatial data for Scheduled Monuments, part of the National Heritage list for England. Scheduled monuments are represented by a polygon defining the extent of the statutorily protected area.

Archaeological sites of national importance are given legal protection by being placed on a ‘Schedule’ of monuments. Under the Ancient Monuments and Archaeological Areas Act 1979, the Welsh Ministers are required to compile and maintain this schedule.

SSSI are the finest sites for wildlife and natural features in England, supporting many characteristic, rare and endangered species, habitats and natural features. The data is updated approximately yearly and does not include 'proposed' sites.
