By default Google Maps does not show you the latitude or longitude of a location. Also, there is no option to show those values as well. But what if you need the latitude and longitude? For a GPS unit perhaps?
Basically all you need to do is copy and paste the following snippet of code into the address bar of your browser while your on Google Maps.
javascript:void(prompt(”,gApplication.getMap().getCenter()));
This hack only shows the latitude and longitude in the center of the map so make sure the location you want is centered before you paste the code.
