  • This spatial dataset relates to Phase 1 (2006) and consists of 4 individual layers, being Points (individual trees), polygons (groups of trees), urban extents (the extent of the study areas) and land use classifications. The technical report shows what is covered in each Phase, and provides more detail on the methodology behind the different layers in the dataset. This data was captured using

  • This spatial dataset relates to Phase 3 (2013) of Urban Tree Cover and consists of 3 individual layers, being Points (individual trees), polygons (groups of trees) and urban extents (the extent of the study areas). Unlike Phase 1 and 2 land use classifications were not created for phase 3. The technical report shows what is covered in each Phase, and provides more detail

  • This dataset comprises of polygons relating to each site identified under the Bathing Water Directive (76/160/EEC); however these polygons have no formal status under the Bathing Water Directive. Where a site corresponds to a Sensitive Area under the Urban Waste Water Treatment Directive (UWWTD) in England & Wales, the polygon for that Sensitive Area is provided. For all other sites the

  • Built-up areas are defined as land which is ‘irreversibly urban in character’, meaning that they are characteristic of a village, town or city. They include areas of built-up land with a minimum of 20 hectares (200,000m2). Any areas with less than 200 metres between them are linked to become a single built-up area.

  • Most Country Parks were designated in the 1970s, under the Countryside Act 1968 with the support of the former Countryside Commission. In more recent times there has been no specific financial support for Country Parks directly, and fewer have been designated. Most are managed by local authorities, although other organisations and private individuals can also run them. A Country Park is an area

  • This spatial Flood Warning Areas dataset are geographical areas where NRW expect flooding to occur and where NRW provide a Flood Warning Service. Flood Warning Areas generally contain properties that are expected to flood from rivers or the sea. Specifically, Flood Warning Areas define locations within the Flood Warning Service Limit that represent a discrete community at risk of flooding. A

  • Light Detection and Ranging (LiDAR) is an airborne mapping technique, which uses a laser to measure the distance between the aircraft and the ground.  Up to 100,000 measurements per second are made of the ground, allowing highly detailed surface and terrain models to be generated at different spatial resolutions.

  • This spatial dataset contains the digital boundaries of Local Nature Reserves (LNRs) in Wales. Local Nature Reserves are established and managed by local authorities, following consultation with Natural Resources Wales (NRW) under the National Parks and Access to the Countryside Act 1949. For a site to become an LNR it must have natural features of special interest to the local area, and the

  • The CRoW Act provides for public access on foot to certain types of land, amends the law relating to public rights of way, increases measures for the management and protection for Sites of Special Scientific Interest (SSSI) and strengthens wildlife enforcement legislation, and provides for better management of Areas of Outstanding Natural Beauty (AONB). Under Section 4 of the CRoW Act it states

  • This is a spatial dataset showing the extent of the Urban Wastewater Treatment Directive (UWWTD) sensitive areas (bathing waters) in Wales. The UWWTD (91/271/EEC) regulates the collection and treatment of waste water from homes and from industry. In the UK, the directive is implemented through the Urban Wastewater Treatment regulations 1994. Under these regulations, water bodies where treatment

  • This dataset consists of 3 shapefiles showing the extent of Urban Wastewater Treatment Directive (91/271/EEC) (UWWTD) sensitive areas (eutrophic). The UWWTD describes eutrophication as 'the enrichment of water by nutrients, especially compounds of nitrogen and/or phosphorous, causing an accelerated growth of algae and higher forms of plant life to produce an undesirable disturbance to the balance

  • Working with Natural Processes (WWNP) Riparian Woodland Potential is our best estimate of locations where tree planting may be possible on smaller floodplains close to flow pathways, and effective to attenuate flooding. The dataset is designed to support signposting of riparian areas not already wooded. The dataset is based upon a 50m buffer of available OS Open Data river networks. A set of open

  • This dataset comprises a range of land cover types where the woodland potential layers have been masked, owing to existing woodland, watercourses, peat, roads, rail and urban areas. Other constraints data, such as protected habitats and high grade agricultural land, should also be considered.

    Locations identified may have more recent land use change than available at the time of publication.
