The OS MasterMap Topography Layer is a large-scale digital database of the detailed surface features on the landscape, with relative positions and elevations of every town, manor, parish, or tract of land mapped to minute detail. This highly accurate, flexible resource covers some 400 million man-made and natural features, from fields to pillar boxes, each with its own unique identifier or TOID® for easy reference. It is broken down into nine themes to make it easier to access the data; roads, tracks and paths; land; buildings; water; rail; height; heritage; structures; and administrative boundaries. There is the choice of a single theme, a combination of themes or all of the above. When overlaid with other OS MasterMap layers or the customer's own data, it will provide a clear picture of what's on the ground. The Topography Layer helps in the planning and management of land and property by enabling users to visualise the context of any feature or site, to pinpoint individual properties and precise sites when a high level of detail is required, and to assess the impact of a proposed development effectively and efficiently. It is data association that makes OS MasterMap intelligent. It enables organisations to link their own data to that of the digital map. By associating their data to the OS MasterMap features, organisations are then able to analyse a richer database, and can search and query using their own data fields as well as the attributes provided by OS MasterMap.

Great Britain's (England, Scotland, Wales) rivers, watercourses and water bodies represented as a connected network, polygons and/or lines. This data is often used for environmental monitoring and risk assessment, navigation, statistical analysis. OS Rivers Data includes freshwater rivers, tidal estuaries, lakes and canals as well as water flowing through aqueducts, tunnels and underground. Additional attribution, including name, type, height, flow direction, gradient, length, width and source is available in various OS data products. OS Rivers Data is supplied in a number of OS data products, including: OS MasterMap Water Network Layer, OS Open Rivers, OS MasterMap Topography Layer, VectorMap Local and VectorMap District. Small-scale cartographic representations are also availble in OS catpgraphic products. All data is collected by Ordnance Survey. Culvert data within OS MasterMap Water Network Layer is sourced from Scottish Local Authorities. as part of their role as the National Mapping Agency of Great Britain.

Large-scale, accurate and fully attributed digital river centreline covering England and Wales. The dataset has full-feature network geometry cross-referenced with OS MasterMap following Digital National Framework principles. The dataset has full-feature network geometry cross-referenced with OS MasterMap following Digital National Framework. It is made of the three following layers: - Links: lines representing the river network. It is a river centreline dataset, based on OS MasterMap for surface features and Environment Agency culvert surveys for underground features (where available). There are many attributes associated with this dataset to enable it to be used for many different business purposes. It is topologically correct to allow it's use in network tracing tasks. - Offline Drainage: lines representing the sections of river and drains that do not obviously connect to the main online drainage network represented by the DRN. Sections with uncertain flow direction and connectivity are presented here, although in reality some may connect to the main DRN, and be added to it as more information becomes available. - Nodes: points representing the junctions between discrete stretches of the online DRN. It is used to assist in connectivity and flow direction, as every DRN stretch is attributed with the 'from' and 'to' nodes. Nodes are also included where line features cross, but do not intersect, such as an aqueduct passing over a river. Nodes have types to determine whether they are at for example junction or at a change in river type.

The NFI definition of woodland is a minimum area of 0.5 hectares under stands of trees with, or with the potential to achieve, tree crown cover of more than 20% of the ground. Areas of young trees, which have the potential to achieve a canopy cover of more than 20%, will also be interpreted as woodland and mapped. The minimum width for woodland is 20 m, although where woodlands are connected by a narrow neck of woodland less than 20 m wide, the break may be disregarded if less than 20 m in extent. Intervening land classes such as Roads - all 'tarmac' roads should be excluded from the woodland area, but internal forest tracks, farmers tracks, rides etc. will be included as part of the woodland if< 20m wide. Rivers - where the gap in woodland is 20m then rivers will be excluded from the woodland area.Power lines etc. - where the gap in woodland is 20m then power lines will be excluded from the woodland area.Railways - all normal gauge railways should be excluded from woodland Scrubby vegetation" is included within this survey where low woody growth seems to dominate a likely woodland site. The definition of an open area is any open area that is 20m wide and 0.5 ha in extent and is completely surrounded by woodland.The woodland boundaries have been interpreted from colour aerial orthophotographic imagery. For the base map, photographic images aimed to be no older than 3 years at the time of mapping (i.e. areas mapped in 2007 would be based on photographs that were ideally taken no earlier than 2004). As the map is be the basis for a longer rolling programme of sample field surveys it has been necessary to develop procedures to update the map to the date of the field survey, currently 2011, for the purpose of reporting on the current phase.The map is continually updated on an annual basis. These updates will are achieved by a combination of remote sensing and updated aerial imagery analysis for changes in the woodland structure and with reference to available new planting information from grant schemes and the FE sub-compartment database. Ordnance Survey MasterMap® (OSMM) features have been used as a reference for capturing the woodland boundaries. OSMM is the most up to date large-scale digital map of GB providing a seamless database for 1:1250, 1:2500 and 1:10000 survey data. All woodland (both urban and rural, regardless of ownership) which is 0.5ha or greater in extent, with the exception of Assumed woodland or Low density areas that can be 0.1ha or greater in extend, as been mapped Woodland that is less than 0.5ha in extent will not be described within the dataset but will be included in a separate sample survey of small woodland and tree features. The primary objective is to create a new digital map of all woodland in Great Britain using O.S.MasterMap features as boundaries where appropriate. The map shows the extent of all woodland of 0.5 ha.Woodland categories are defined by IFT (Interpreted Forest Type) values.

Gardens and designed landscapes are grounds which have been laid out for artistic effect and, in appropriate cases, include references to any buildings, land, or water on, adjacent, or contiguous to such grounds. Sites included in the Inventory of Gardens and Designed Landscapes are nationally important. The criteria for determining national importance is published in Annex 5 of the Scottish Historic Environment Policy 2011. The duty to compile and maintain the Inventory is statutory. Historic Environment Scotland manages this work on behalf of the Scottish Ministers. There is no primary legislation that affords protection to Inventory gardens and designed landscapes. However, Inventory status is a material consideration in the planning system.The geography of the Inventory has been derived from Ordnance Survey background mapping. The features initially were digitized from the published Inventory. Boundaries were subsequently obtained using OS Mastermap and OS Landline at scales 1:2500 and 1:1250.

The Inventory of Historic Battlefields is a list of nationally important battlefields in Scotland that meet the criteria published in SHEP 2009. It provides information on the sites to raise awareness of their significance and assist in their protection and management for the future. It is a major resource for enhancing the understanding, appreciation and enjoyment of battlefields, for promoting education and stimulating further research, and for developing their potential as attractions for visitors.The boundaries were defined by GIS tracing against OS Mastermap, at a view scale of around 1:500. Inventory descriptions and maps may be amended from time to time to reflect new evidence, changing knowledge and improved understanding.

Scheduled monuments are nationally important monuments and sites. The aim of scheduling is to preserve sites and monuments as far as possible in the form in which they have come down to us today. They are legally protected through the Ancient Monuments and Archaeological Areas Act 1979. National importance takes account of a wide range of factors, including artistic, archaeological, architectural, historic, traditional, aesthetic, scientific and social. Guidance and criteria to assess national importance of monuments is set out by Scottish Ministers in The Scottish Historic Environment Policy. This data allows you to identify the approximate position, size and extent of scheduled monuments in Scotland.Scheduling is an ongoing process. We assess and reassess monuments as our knowledge and understanding of what survives and its importance changes. Sometimes monuments are amended to bring the maps and descriptions up-to-date. Data is updated on weekly basis unless no cases have been brought forward. Designation polygons were originally derived from legal documentation. Amendments are informed by a combination of methods: field visits; differential GPS; aerial photography and OS mapping (Mastermap - scale 1:2500).

This spatial dataset contains the digital boundaries of Sites of Special Scientific Interest (SSSIs) in Wales. SSSIs cover a wide range of habitats from small fens, bogs and riverside meadows to sand-dunes, woodlands and vast tracts of uplands. Most are in private ownership, although some are owned and managed by local wildlife trusts, or other voluntary conservation bodies. Notification of an SSSI under the Wildlife and Countryside Act 1981 has since been amended by the Countryside and Rights of Way Act 2001, which brought about numerous changes in the way SSSI are notified managed and protected. In order to ensure consistent, favourable long-term management of these sites, Natural Resources Wales (NRW) with landowners have prepared management plans for all SSSI in Wales. Local plan ning authorities are required to consult NRW before allowing any development to proceed that may affect an SSSI. Water, gas and electricity companies must also do the same. SSSIs have been designated, from 1949 to the present day, and are on-going. The data has been held digitally since the mid-1990s. This data has been checked by relevant NRW staff. Please refer to the designation map as the legal definitive boundary. For large SSSIs that were captured digitally and have been printed on a smaller scale map than OS MasterMap, please refer to the OS MasterMap edition at time of capture to view the definitive boundary.

The Listed Building Dataset comprises the statutory addresses and supplementary information for listed buildings in Scotland. Listing is the recognition through the Planning (Listed Buildings and Conservation Areas) (Scotland) Act 1997 that a building or structure is of ‘special’ interest. Historic Environment Scotland lists buildings on behalf of Scottish Ministers.In 2003-4 a programme of geo-referencing listed buildings in Scotland was undertaken in conjunction with the Royal Commission on the Ancient and Historical Monuments of Scotland (RCAHMS). This project linked the known RCAHMS database record coordinates to that of a listed building entry. In addition, where a listed building comprised multiple features, as part of a single listing, these were also captured as entity points. Therefore, a single listing may be represented by one or more points within the dataset. The entity and attribute information is derived from Historic Environment Scotland's Oracle database. is a unique identifier and refers to the statutory address . refers to the entity, or entities, which may form part of a single listing. Boundary information has been derived from Ordnance Survey background mapping. These have been digitized based on relevant mapping at the time of addition, amendment or removal from the list, using OS Mastermap at scales 1:2500 and 1:1250. Boundaries are multipolygon and relate to the single listing entry, including all associated entities.

Updated Boundaries of Ancient Woodland polygons covering England. This is the updated spatial dataset that describes the geographic extent and location of ancient woodland in England (excluding the Isles of Scilly). Ancient Woodland features will be approved county-by-county for publication throughout the first year of production until the data product coverage extends across England. Where available this dataset takes precedence over the Ancient Woodland – England dataset.The update revises the inventory to address problems and gaps in the previous iteration. Technological advances mean that small ancient woodlands (0.25-2ha) are being represented within the inventory for the first time as well as wood pasture and parkland being represented as its own category. The inventory identifies ancient woodland sites in England. Ancient woodland is identified by studying the presence or absence of woods from historic maps, information about the wood's name, shape, internal boundaries, location relative to other features, ground survey, and aerial photography. The information recorded about each wood and stored on the Inventory Database includes its grid reference, its area in hectares and how much is semi-natural or replanted. Prior to the digitisation of the boundaries, only paper maps depicting each ancient wood at 1:50 000 scale were available. Attribution statement: © Natural England 2024. Contains OS data © Crown copyright and database rights 2024. OS AC0000851168.It includes Ancient Semi-Natural Woodland (ASNW), which retains a native tree and shrub cover; Plantation on Ancient Woodland Sites (PAWS), where the original tree cover has been felled and replaced by planting, often with conifers; Ancient Wood Pasture (AWPP), where the trees are managed in tandem with a long established tradition of grazing, characteristically with at least some veteran trees or shrubs or; Infilled Ancient Wood Pasture (IAWPP) which has become infilled with trees arising from planting or natural regeneration.Updated Boundaries of Ancient Woodland polygons covering England. This is the updated spatial dataset that describes the geographic extent and location of ancient woodland in England (excluding the Isles of Scilly). Ancient Woodland features will be approved county-by-county for publication throughout the first year of production until the data product coverage extends across England. Where available this dataset takes precedence over the Ancient Woodland – England dataset. The AWI Update project will deliver an accurate inventory of the entirety of England’s ancient woodland resource, including those woods smaller than 2ha which are currently not mapped on the AWI. It will also ensure that the AWI is used and respected by planners, developers, land managers and all those who make and use spatial plans in England’s countryside.The ancient woodland boundaries are digitised to OS MasterMap - assessed by licencing staff as suitable for OS Presumption to Publish process. However, the maps that Ancient Woodlands are based upon include the OS 1” First Edition maps, the OS 1:25 000 and the OS 1:50 000 maps. The boundaries cannot be taken as precise, especially where they are surrounded by woodland, and are only precisely comparable with other boundaries at the 1” map scale (1:63 360). The inventory identifies over 22,000 ancient woodland sites in England. 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. The information recorded about each wood and stored on the Inventory Database includes its grid reference, its area in hectares and how much is semi-natural or replanted. Prior to the digitisation of the boundaries, only paper maps depicting each ancient wood at 1:50 000 scale were available. The datasets consulted: OS MasterMap, OS First Edition Maps (Historic County Series Maps Epoch 1-4), Historic OS Drawings, Aerial Imagery, Original AWI Datasheets, Open Source old historical maps (varies depending on county agreements), BSBI Indicator species data, County Tithe Maps, Forestry Commission National Forest Inventory and Forest Condition Survey. Besides the isolated and modified woodland boundaries derived from OS MasterMap that have been identified Ancient Woodland, additional third party data is viewed for informative purposes only during the creation of the project layer. No data from any other of these third party sources is copied, transferred or viewable in the layer to be published."Full metadata can be viewed on data.gov.uk.
