Markdown versions of all pages are available by appending .md to any URL. # UK OS Open Zoomstack schema The vector tile schema describes how the vector data is organized into different thematic layers and which attribute and values each layer contains. This is useful for writing a map style. Ordnance Survey's OS Open Zoomstack is an open vector basemap showing coverage of Great Britain from a national level, right down to street detail. Explore the tileset in the interactive map viewer, check the date of the last update, use it as vector tiles, etc. [Go to UK OS Open Zoomstack](https://cloud.maptiler.com/tiles/uk-openzoomstack/) ## Maps with this tileset [![UK OS Open Zoomstack light map](https://cloud.maptiler.com/static/img/maps/uk-openzoomstack-light.png) UK OS Open Zoomstack light ](https://cloud.maptiler.com/maps/uk-openzoomstack-light/)[![UK OS Open Zoomstack dark map](https://cloud.maptiler.com/static/img/maps/uk-openzoomstack-night.png) UK OS Open Zoomstack dark ](https://cloud.maptiler.com/maps/uk-openzoomstack-night/)[![UK OS Open Zoomstack outdoor map](https://cloud.maptiler.com/static/img/maps/uk-openzoomstack-outdoor.png) UK OS Open Zoomstack outdoor ](https://cloud.maptiler.com/maps/uk-openzoomstack-outdoor/)[![UK OS Open Zoomstack road map](https://cloud.maptiler.com/static/img/maps/uk-openzoomstack-road.png) UK OS Open Zoomstack road ](https://cloud.maptiler.com/maps/uk-openzoomstack-road/) ## Definition of layers The UK OS Open Zoomstack tileset contains the following layers: ## airports [#](#airports) A centre point for all major airports including a name. ### Fields #### name Name of airport. ## boundaries [#](#boundaries) National boundary lines between England - Scotland and England - Wales. ### Fields #### type Type of boundary line. Possible values: - `National` ## buildings [#](#buildings) Generalised building footprints at both local and district resolutions. The local buildings have a unique identifier which can be used to style features distinctly. The identifier will not be persistent between product versions and therefore there will be no change history information for a feature. ### Fields #### uuid ## contours [#](#contours) These contours lines have a 10-metre interval with an index every 50 metres. Each contour contains a value. ### Fields #### type Type of contour line. Possible values: - `Index` - `Normal` #### value Contour line elevation. ## etl [#](#etl) Electricity Transmission Lines. ## foreshore [#](#foreshore) These polygons depict the part of the shore or beach which lies between the Mean Low Water Mark and Mean High Water Mark. ## greenspaces [#](#greenspaces) Polygon features representing the extent of places such as parks and sports facilities that are likely to be accessible to the public. ### Fields Type of greenspace. #### type Possible values: - `Allotments Or Community Growing Spaces` - `Bowling Green` - `Cemetery` - `Golf Course` - `Other Sports Facility` - `Play Space` - `Playing Field` - `Public Park Or Garden` - `Religious Grounds` - `Tennis Court` ## names [#](#names) Use this point layer to render contextual labels on your map. The `name1language` and `name2language` attributes let you select which names to display. For example, if you want to show all the Welsh language names then you can use these attributes to filter them out and These are the attribute values in the language fields: - `cym` - name is in the Welsh language. - `eng` - name is in the English language. - `gla` - name is in the Scottish Gaelic language. - `NULL` - language type is not set if there is only one name, or if there are two names, and the language of one or both of the names is not recorded as English, Welsh or Gaelic. ### Fields #### type Possible values: - `Country` - `Capital` - `National Park` - `City` - `Town` - `Village` - `Hamlet` - `Small Settlements` - `Suburban Area` - `Woodland` - `Landform` - `Landcover` - `Water` - `Greenspace` - `Sites` - `Motorway Junctions` #### name1 Contains the accepted or English name. #### name1language Let you select which names to display. For example, if you want to show all the Welsh language names then you can use these attributes to filter them out and render them on your map. Possible values: - NULL - `eng` #### name2 Contains the Welsh, Gaelic or English name #### name2language Let you select which names to display. For example, if you want to show all the Welsh language names then you can use these attributes to filter them out and render them on your map. Possible values: - NULL - `cym` - `gla` ## national\_parks [#](#national_parks) These polygons depict the extent of the 15 National Parks in Great Britain. ## rail [#](#rail) Lines representing the railway network. They are broken where they pass under bridges, buildings or other obstructing detail. ### Fields #### type Type of rail. Possible values: - `Multi Track` - `type` - `Single Track` - `Narrow Gauge` - `Tunnel` ## railwaystations [#](#railwaystations) This layer contains a point for all stations and includes a name. ### Fields #### type Type of railway station Possible values: - `Light Rapid Transit Station` - `Light Rapid Transit Station And London` - `Underground Station` - `Light Rapid Transit Station And Railway Station` - `London Underground Station` - `Railway Station` - `Railway Station And London Underground Station` #### name Name of railway station ## roads [#](#roads) Lines representing the road network. A road is defined as a metalled way for vehicles. ### Fields #### type Type of road. Possible values: - `Motorway` - `Primary` - `A Road` - `B Road` - `roads` - `Guided Busway` - `Minor` - `Local` - `Restricted` - `Tunnels` #### name Name of road #### number Number of road #### level Level of road. Possible values: - `0` - `1` - `2` ## sea [#](#sea) This layer depicts the sea around Great Britain. ## sites [#](#sites) Polygon features that represent the area or extent of certain types of function or activity. ### Fields #### type Type of site. Possible values: - `Air Transport` - `Education` - `Medical Care` - `Road Transport` - `Water Transport` ## surfacewater [#](#surfacewater) These polygons represent inland water bodies that are sufficiently wide enough to be captured as an area. ## urban\_areas [#](#urban_areas) These are generalised polygons representing built-up areas for use at smaller scales. ## waterlines [#](#waterlines) Lines representing rivers, canals, drains and other linear bodies of water. ### Fields #### type Type of waterline. Possible values: - `National` - `Regional` - `District` - `Local` - `MHW` - `MLW` ## woodland [#](#woodland) The polygons represent areas of trees: coniferous, non-coniferous and mixed. ## License With the use of this API, you must visibly credit these attributions: [© MapTiler](https://www.maptiler.com/copyright/) [Contains OS data © Crown copyright and database right 2022](https://www.ordnancesurvey.co.uk/)
