Google has a new experimental service that lets you build Google Earth tours from your browser. It’s called Tour Builder and it requires the Google Earth Plugin (you also get the plugin when you install Google Earth).
“Tour Builder is a new way to show people the places you’ve visited and the experiences you had along the way using Google Earth. It lets you pick the locations right on the map, add in photos, text, and video, and then share your creation. We originally created Tour Builder to give veterans a way to record all the places that military service has taken them, and preserve their stories and memories as a legacy for their families. But we also thought it could be a useful tool for anyone with a story to tell, so we made it available to everyone,” explains Google.
