Product supply

Available formats

OS MasterMap Greenspace Layer is supplied in four different formats:

• GML 3.2.1

• ESRI Shapefile

• GeoPackage

• Vector tiles (MBTiles)

Product supply mechanism

OS MasterMap Greenspace Layer incorporates a web-based ordering system that allows customers to order their initial data supply and any updates, obtain price estimates and view details of their holdings on demand. The product is supplied as an online download. You can download data in any of the available formats from the OS Data Hub.

Coverage

OS MasterMap Greenspace Layer covers all major urban areas in Great Britain.

For England and Wales, urban areas are included where they are greater than 6km².

For Scotland, urban areas are defined as those with a population more than 500. This is based on data provided by the National Records of Scotland. In Scotland a buffer of 500 m has been added to the urban extents to define the product coverage.

Where a site crosses the boundary of an area, all features within the site are included in OS MasterMap Greenspace Layer, even where these are outside the urban area. This applies up to a limit of 1 500 m from the urban boundary.

A coverage extent map and downloadable GIS files are available at the bottom of the OS MasterMap Greenspace Layer Product Support page on the OS website.

File size

For all formats the data is only available as full supply (that is, not as a Change Only Update – COU). Orders of Great Britain (GB) only are available across all four formats. Area of Interest (AOI) orders are only available in GML or Shapefile formats.

For Shapefile format, the product is supplied in 5 km-by-5 km tiles of data in either a specified AOI or GB supply. Tile file size estimates can vary from 2 KB to 10 900KB.

For GeoPackage and vector tiles formats, the coverage will be GB only. The file size is 6.83 GB zipped for GeoPackage and 11.5 GB zipped for vector tiles.
