The OS NGD Structure Features Collection gives you access to a standalone dataset containing the most current and comprehensive structures data captured by Ordnance Survey.
Structures are defined as features which are of manmade construction but are not buildings, for example, dams, hedges, bridges, chimneys, statues, post boxes, cranes, cattle grids, and sea walls. These features can have point, line, or polygon geometry.
The OS NGD Structure Features Collection allows you to:
Ensure your structures data is always completely up to date with up to daily updates.
Perform powerful analytics, underpinned by unrivalled OS accuracy.
Quickly interpret structure type using the Description attribute value (such as a roofed storage tank, a chimney, or a telecommunications mast).
Use enhanced change metadata to monitor and understand how structures are changing.
Easily perform feature counts for Compound Structures (this feature type is explained below) to understand the quantity present within your area of interest.
Up to daily updates to data.
Plug and play – the data is simple and quick to implement as you don't need to pre-process it before you use it.
Rich attribution ensures the data is straightforward to navigate and query.
Simplified attribute naming helps make names easier to understand.
Persistent unique identifiers with lifecycle information.
Name attribution (if known) available for features, so you can identify what a structure is called.
Land use classification provided for the Structure Feature Type, helping you understand feature function.
The Compound Structure Feature Type combines multiple polygons into a single polygon, making it easier for you to analyse and query data when you want to analyse a structure as a single part rather than its constituent parts.
Height data available for chimneys, roofed tanks and glasshouse features.
The Field Boundary Feature Type identifies the location and nature of a physical boundary feature when adjacent to specific types of land cover.
Bridge interaction attributes (Network Over and Network Under) identify the type of networks (road, path, railway, canal, water or multiple) passing over and under bridges.
Land use classification (for example, residential accommodation) provided for the Structure Feature Type to indicate the prominent use of the Site which contains the structure.
National land use standards used to provide universal insights for human activity (NLUD classification and BS7666 national addressing classification).
An Office for National Statistics (ONS) Government Statistical Service (GSS) code is provided for Structure features within Lower Tier Local Authority areas to indicate which Lower Tier Local Authority boundary the feature lies within.
Great Britain. However, Field Boundary features are predominately located in Rural and Moorland areas.
British National Grid (EPSG: 27700).
The earliest date on which you can request a one-off snapshot of a date in the past for data in this collection is noted at the top of the individual feature type pages.
GeoPackage, CSV (comma-separated values), GeoJSON or vector tiles (the latter format is not available for one feature type in the collection: Structure Point).
