"Tour the world with a bird's-eye view from Google Earth.
http://earth.google.com/
"The program lets you view satellite and aerial photos of pretty much any spot on the planet. In big metropolitan areas in the US, Canada and Western Europe you can locate and zoom in on Individual buildings and houses, and see cars and trees. The program rapidly fetches the images from the Internet and visually "flies" you from place to place around the globe"
(Me Again) If this program allows you to zoom in on trees and cars, I would say it should allow you to view churchyards?
Good Luck Everyone
