Google reverse geocoding

Reverse geocoding is the process of converting geographic coordinates into a human-readable address.

google_reverse_geocode(location, result_type = NULL,
  location_type = NULL, language = NULL,
  key = get_api_key("reverse_geocode"), simplify = TRUE,
  curl_proxy = NULL)

Arguments

location	numeric vector of lat/lon coordinates.
result_type	string vector - one or more address types. See https://developers.google.com/maps/documentation/geocoding/intro#Types for list of available types.
location_type	string vector specifying a location type will restrict the results to this type. If multiple types are specified, the API will return all addresses that match any of the types
language	string specifies the language in which to return the results. See the list of supported languages: https://developers.google.com/maps/faq#using-google-maps-apis. If no langauge is supplied, the service will attempt to use the language of the domain from which the request was sent
key	string. A valid Google Developers Geocode API key
simplify	logical - TRUE indicates the returned JSON will be coerced into a list. FALSE indicates the returend JSON will be returned as a string
curl_proxy	a curl proxy object

Value

Either list or JSON string of the geocoded address

API use and limits

The amount of queries you can make to Google's APIs is dependent on both the service and the API you are using.

Each API has specific quotas and limits. Check Google's API documentation for details.

View your usage at the Google Cloud Console https://console.cloud.google.com/

Each API can only accept and return one request at a time. If you write a loop to make multiple API calls you should ensure you don't go over your quota / limits during the loop.

Examples

# NOT RUN {
## searching for the street address for the rooftop location type
google_reverse_geocode(location = c(-37.81659, 144.9841),
                       result_type = c("street_address"),
                       location_type = "rooftop",
                       key = "<your valid api key>")
# }
