GoLang package that provides an easy way to use the Google Geocoding API.
See more information about the Google Geocoding API at the following link: https://developers.google.com/maps/documentation/geocoding/start
You can use go get:
go get github.com/kelvins/geocoder Example of usage:
package main import ( "fmt" "github.com/kelvins/geocoder" ) func main() { // This example should work without need of an API Key, // but when you will use the API in your project you need // to set your API KEY as explained here: // https://developers.google.com/maps/documentation/geocoding/get-api-key // geocoder.ApiKey = "YOUR_API_KEY" // See all Address fields in the documentation address := geocoder.Address{ Street: "Central Park West", Number: 115, City: "New York", State: "New York", Country: "United States", } // Convert address to location (latitude, longitude) location, err := geocoder.Geocoding(address) if err != nil { fmt.Println("Could not get the location: ", err) } else { fmt.Println("Latitude: ", location.Latitude) fmt.Println("Longitude: ", location.Longitude) } // Set the latitude and longitude location = geocoder.Location{ Latitude: 40.775807, Longitude: -73.97632, } // Convert location (latitude, longitude) to a slice of addresses addresses, err := geocoder.GeocodingReverse(location) if err != nil { fmt.Println("Could not get the addresses: ", err) } else { // Usually, the first address returned from the API // is more detailed, so let's work with it address = addresses[0] // Print the address formatted by the geocoder package fmt.Println(address.FormatAddress()) // Print the formatted address from the API fmt.Println(address.FormattedAddress) // Print the type of the address fmt.Println(address.Types) } }Results:
Latitude: 40.7758882 Longitude: -73.9764703 115, Central Park West, Manhattan, 10023, New York, New York County, New York, United States 115 Central Park West, New York, NY 10023, USA street_address You can access the full documentation here:

With a little more effort you can use goroutines with channels:
package main import ( "fmt" "time" "github.com/kelvins/geocoder" ) // Use the channels system to call the Geocoding function func geocodingChannel(address geocoder.Address, locationChan chan geocoder.Location, errChan chan error) { fmt.Println("Entering geocodingChannel function...") defer fmt.Println("Exiting geocodingChannel function...") defer close(locationChan) defer close(errChan) location, err := geocoder.Geocoding(address) locationChan <- location errChan <- err } // Use the channels system to call the GeocodingReverse function func geocodingReverseChannel(location geocoder.Location, addressesChan chan []geocoder.Address, errChan chan error) { fmt.Println("Entering geocodingReverseChannel function...") defer fmt.Println("Exiting geocodingReverseChannel function...") defer close(addressesChan) defer close(errChan) addresses, err := geocoder.GeocodingReverse(location) addressesChan <- addresses errChan <- err } func main() { // See all Address fields in the documentation address := geocoder.Address{ Street: "Central Park West", Number: 115, City: "New York", State: "New York", Country: "United States", } // Make the channels locationChan := make(chan geocoder.Location) errChan := make(chan error) // Call the go routine go geocodingChannel(address, locationChan, errChan) // Do whatever you need to do for index := 0; index < 5; index++ { fmt.Println(index) time.Sleep(50 * time.Millisecond) } // Get the results location := <-locationChan err := <-errChan // Check if the results are valid if err != nil { fmt.Println("Could not get the location: ", err) } else { fmt.Println("Latitude: ", location.Latitude) fmt.Println("Longitude: ", location.Longitude) } // Set the latitude and longitude location = geocoder.Location{ Latitude: 40.775807, Longitude: -73.97632, } // Make the channels addressesChan := make(chan []geocoder.Address) errChan = make(chan error) // Call the go routine go geocodingReverseChannel(location, addressesChan, errChan) // Do whatever you need to do for index := 0; index < 5; index++ { fmt.Println(index) time.Sleep(50 * time.Millisecond) } // Get the results addresses := <-addressesChan err = <-errChan // Check if the results are valid if err != nil { fmt.Println("Could not get the addresses: ", err) } else { fmt.Println(addresses[0].FormattedAddress) } }
