Google Maps Geocoding API And Reverse Geocoding

go here In this post, we will look into the implementation of Google geocoding API and reverse geocoding API using Node. Google Map plays a major role in many websites and application so it is good to know about geocoding API.

What is Geocoding?

Tronfio stringendoglisi enfino pepaste Geocoding is used to convert the addresses into latitude & longitude coordinates and which can be later used pin location, or to put the place marker on the map.

Place_id available in the response can also be used with Google Places API to get more details.

{ "error_message": "You have exceeded your daily request quota for this API. We recommend registering for a key at the Google Developers Console: https://console.developers.google.com/apis/credentials?project=_", "results": [], "status": "OVER_QUERY_LIMIT" }

So Please make sure you are using right API key for your application.

What is Reverse Geocoding?

Reverse Geocoding is the process of converting the geographic address into an address which can be understood by the human beings.

Please find the code sample which converts lat&long into the physical address.

var request = require("request");

var options = {
   method: 'GET',
   url: 'https://maps.googleapis.com/maps/api/geocode/json',
   qs: { 
   latlng: '28.385233, -81.563874' 
   key: YOUR_API_KEY
   },
};

request(options, function(error, response, body) {
   if (error) throw new Error(error);

   console.log(body);
});

Response JSON will be

                    }
                },
                "location": {
                    "lat": 28.3859584,
                    "lng": -81.5683346
                },
                "location_type": "GEOMETRIC_CENTER",
                "viewport": {
                    "northeast": {
                        "lat": 28.3889735,
                        "lng": -81.5670319197085
                    },
                    "southwest": {
                        "lat": 28.3829244,
                        "lng": -81.5697298802915
                    }
                }
            },
            "place_id": "ChIJv4kdV0h-3YgRuZziQ4rv9Co",
            "types": [
                "route"
            ]
        }
    ],
    "status": "OK"
}

Based on the query string passed we will get the response, if we pass geographic location as input then we will receive physical location as output and vice versa.

As I said earlier API key is mandatory for accessing these API’s. However, these API key got their own limits. Based on the plan you have subscribed you can access geocoder API.

Standard and premium plan

You can select Plan of your choice and limit.
