The data is categorised into broad typologies of: Amenity; Outdoor Sports Facilities; Parks and Gardens; Natural and Semi-natural; Allotments, Community Gardens and Urban Farms; Cemeteries; Institutional; Provision for Children and Young People and Agricultural. Typologies are then further split down into sub-typologies where known.

Some features overlay other feature e.g. some Outdoor Sports Facilities sit within a Park and Garden. This is denoted by the 'WHOLE_PART' field and the 'Part of Larger Site' features should be excluded when considering total open space for the whole city.

Please see the Data Definition document for further details.
