GeoCodeTypeUnknown,
StreetAddress, // indicates a precise street address.
Route, // indicates a named route (such as "US 101").
Intersection, // indicates a major intersection, usually of two major roads.
Political, // indicates a political entity. Usually, this type indicates a polygon of some civil administration.
Country, // indicates the national political entity, and is typically the highest order type returned by the Geocoder.
AdministrativeAreaLevel1, // indicates a first-order civil entity below the country level. Within the United States, these administrative levels are states.
AdministrativeAreaLevel2, // indicates a second-order civil entity below the country level. Within the United States, these administrative levels are counties.
AdministrativeAreaLevel3, // indicates a third-order civil entity below the country level. This type indicates a minor civil division.
ColloquialArea, // indicates a commonly-used alternative name for the entity.
Locality, // indicates an incorporated city or town political entity.
Sublocality, // indicates a first-order civil entity below a locality. For some locations may receive one of the additional types: sublocality_level_1 through to sublocality_level_5. Each sublocality level is a civil entity. Larger numbers indicate a smaller geographic area.
SublocalityLevel1,
SublocalityLevel2,
SublocalityLevel3,
SublocalityLevel4,
SublocalityLevel5,
Neighborhood, // indicates a named neighborhood
Premise, // indicates a named location, usually a building or collection of buildings with a common name
Subpremise, // indicates a first-order entity below a named location, usually a singular building within a collection of buildings with a common name
PostalCode, // indicates a postal code as used to address postal mail within the country.
NaturalFeature, // indicates a prominent natural feature.
Airport, // indicates an airport.
Park, // indicates a named park.
PointOfInterest, // indicates a named point of interest. Typically, these "POI"s are prominent local entities that don't easily fit in another category such as "Empire State Building" or "Statue of Liberty."
Floor, // indicates the floor of a building address.
Establishment, // typically indicates a place that has not yet been categorized.
Parking, // indicates a parking lot or parking structure.
PostBox, // indicates a specific postal box.
PostalTown, // indicates a grouping of geographic areas, such as locality and sublocality, used for mailing addresses in some countries.
RoomIndicates, // the room of a building address.
StreetNumber, // indicates the precise street number.
BusStation, // indicate the location of a bus stop.
TrainStation, // indicate the location of a train stop.
TransitStation, // indicate the location of a public transit stop.
