If you want to copy the latitude and longitude values from Google Maps, you can use the little LatLng Marker application in Google Maps.
1. Go to http://maps.google.com
2. Click on “New!”
3. Enable LatLng Marker
Then you can select an copy paste the the latitude and longitude coordinates.
It says click “New”. Where is “New”? Menu? Upper corner lower? Need to log in?
