How to retrieve geographical location from users using Angular

rated 0 times [ 90] [ 5] / answers: 1 / hits: 21880 / 6 Years ago, thu, may 24, 2018, 12:00:00

I'm programming in Angular with Openlayers library.
I want to use this API : https://adresse.data.gouv.fr/api (the page is in french so I will explain the purpose)

The goal of this API is on the one hand to search some adresses on a map while building GeoJSON files and on the other hand to use a reverse geocoding. This is why I need geographical location from the user.

For example this request : http 'https://api-adresse.data.gouv.fr/search/?q=8 bd du port' will return all the streets in the world answering to the name 8 bd du port

So I want to use the reverse geocoding and create a request like this : http 'https://api-adresse.data.gouv.fr/reverse/?lon=user_lon&lat=user_lat'

It is the best way to proceed ? I don't want to use an another API like Google one

You can use the HTML standard Geolocation api for this.

  getLocation(): void{

    if (navigator.geolocation) {

        navigator.geolocation.getCurrentPosition((position)=>{

          const longitude = position.coords.longitude;

          const latitude = position.coords.latitude;

          this.callApi(longitude, latitude);

        });

    } else {

       console.log(No support for geolocation)

    }

  }



  callApi(Longitude: number, Latitude: number){

    const url = `https://api-adresse.data.gouv.fr/reverse/?lon=${Longitude}&lat=${Latitude}`

    //Call API

  }
