Grounds

European Economic Area (EEA) developers

The grounds field within the Geocoding response contains a single grounds that, when populated, gives contextual information about the immediate territory that the geocoding is on. For example:

  • If the geocode is a museum located inside of a park, the grounds may be the park.
  • If the geocode is a shop within a strip mall, the grounds may be the strip mall.
  • If the geocode is a restaurant within a sports complex, the grounds may be the sports complex.
  • If the geocode is a building within a university, the grounds may be the university.
  • If the geocode is an office building within a corporate campus, the grounds may be the corporate campus.

The grounds contains the following values:

  • outline contains the GeoJSON encoding of the polygon that approximates the surface area of the earth covered by the grounds, using the RFC 7946 format
  • name contains the name of the grounds and is an object with subfields language_code and text

Grounds are returned for some, but not all, places with a precise location, such as street addresses, buildings, and establishments. Places that represent large areas, such as cities and regions, won't be returned with grounds.
