Getting Latitude / Longitude from Google Maps
You’ll first look up an address , but this trick only works if the address is centered (it’s centered by default). So, moving the map around will not make this work. When the address you want to find latitude and longitude for is dead center, copy and paste this code into your browser bar:
javascript:void(prompt(”,gApplication.getMap().getCenter()));
Conversely, if you have a lat, long combination you can plug that into Google Maps to show a location:
43.27069053158456, -75.28080940246582
