How to: Find Longitude and Latitude using Google Map

Look up your desired location in Google Maps. The location, if it exists, will be centered on the map. To obtain the longitude and latitude coordinates of this centered location, copy and paste this code into your browser's address bar and press enter:

javascript:void(prompt('',gApplication.getMap().getCenter()));

A dialog box will pop up displaying the coordinates which can be copied and pasted anywhere. The above code can also be bookmarked for efficiency.
