How to accurately retrieve a location's address by using latitude and longitude in TypeScript

When I click on the map, I attempted to retrieve the location address from latitude and longitude. So far, I have successfully obtained the latitude and longitude coordinates upon clicking.

I then tried to use the function below to get the address:

getCurrentLocation(lat,lng): Observable<any> {
        return this._http.get("http://maps.googleapis.com/maps/api/geocode/json?latlng="+lat+","+lng+"&sensor=true")
            .map(response => response.json())
            .catch(error => {
                console.log(error);
                return Observable.throw(error.json());
            });
}

For my typescript function, I imported the following dependencies:

import { } from 'googlemaps';
import { Observable } from 'rxjs/Observable';
import {Http} from '@angular/http';

Despite these efforts, I am still struggling to retrieve the address. Any suggestions or ideas?

Answer №1

Give this a try. I've tested the URL with parameters and it seems to be working smoothly.

fetchLocationData(latitude, longitude): Observable<any> {
    const YOUR_API_KEY = "insert your API key here";
    const url = `https://maps.googleapis.com/maps/api/geocode/json?latlng=${latitude},${longitude}&key=${YOUR_API_KEY}`;
    return this._http.get(url)
         .map(response => response.json())
          .catch(error => {
               console.log(error);
               return Observable.throw(error.json());
          });
    }
