how to get longitude and latitude from google maps code example
Example 1: calculate distance between two latitude longitude points in google maps api
var rad = function(x) {
return x * Math.PI / 180;
};
var getDistance = function(p1, p2) {
var R = 6378137;
var dLat = rad(p2.lat() - p1.lat());
var dLong = rad(p2.lng() - p1.lng());
var a = Math.sin(dLat / 2) * Math.sin(dLat / 2) +
Math.cos(rad(p1.lat())) * Math.cos(rad(p2.lat())) *
Math.sin(dLong / 2) * Math.sin(dLong / 2);
var c = 2 * Math.atan2(Math.sqrt(a), Math.sqrt(1 - a));
var d = R * c;
return d;
};
Example 2: get address from latitude and longitude google map api
Simply pass latitude, longitude and your Google API Key to the following query string, you will get a json array, fetch your city from there.
https://maps.googleapis.com/maps/api/geocode/json?latlng=44.4647452,7.3553838&key=YOUR_API_KEY
Note: Ensure that no space exists between the latitude and longitude values when passed in the latlng parameter.
