Thegrounds field within the Geocoding response contains a single groundsthat, when populated, gives contextual information about the immediateterritory that the geocoding is on. For example:
- If the geocode is a museum located inside of a park, the grounds may be thepark.
- If the geocode is a shop within a strip mall, the grounds may be the stripmall.
- If the geocode is a restaurant within a sports complex, the grounds may be thesports complex.
- If the geocode is a building within a university, the grounds may be theuniversity.
- If the geocode is an office building within a corporate campus, the groundsmay be the corporate campus.
The grounds contains the following values:
