Google Maps do not display latitude and longitude values, but there is an easy trick to get these numbers. This technique will provide the latitude and longitude coordinates of the center of the map displayed by Google Maps.
Looking up an address in Google Maps will center the map on that address if it was found. Because this trick provides the latitude and longitude of the center of the map, moving the map around manually after that will change the center position and this technique will not work accurately.
When the location you want is in the center of the map, copy and paste this code into the location bar of your browser and press enter:
A dialog box will appear, containing the coordinates of the given center of the map!
Search your adress in Google Maps – when found, right click on the displayed pointer – select “center map here” to center the map to this given point.
