My users can create events with geolocation. However, prompting them to introduce a correct geolocation is far from optimal, and asking them to point in a map and then converting the pressed geolocation is a very inaccurate approach.

Geocoder can be used to convert street addresses to geolocations and vice-versa (that is called “reverse geocoding”.
