For now, let's say you have a latitude and longitude and you're ready to see it on a Google Map. Use Google Search. That's right, you can go straight to the simplest page on the Internet—google.com—and enter your latitude and longitude into the search box. Usually coordinates are listed with latitude first, then longitude.
A few users have requested the ability to see the latitude and longitude for their chosen location while using the County Lines on Google Maps tool. This functionality has now been added. As usual, just start by typing in a place name or address for which you want to see nearby county lines, then click "Go!".
