In Google Maps or Google Earth, you can do a search using latitude and longitude coordinates. Here’s a quick tip on how to find coordinates. In Google Earth, browse over to the location for which you’d like to find the coordinates, then click on the “Add Placemark” button in the toolbar. This will automatically put a placemark in the center of the screen and open a dialogue box that shows you the coordinates for that spot, but you can also move the placemark to be able to pinpoint the exact coordinates of a specific location. To do so, click and drag the placemark; you’ll notice that as you drag it, the latitude/longitude coordinates automatically update.
