Google has used Earth and Maps to tell tales of unfolding tragedies and soldiers fighting for our country. Now its opening up those tools to the public, allowing users to build what they're calling "Tours" through Google Earth. Tour Builder was released in honor of Veterans Day and it allows users to create narratives tied to points on a map. The process is pretty simple: you drop a marker, add some text, photos or videos and you're on your way. As you piece together your tale, dropping pins, you can pull the viewer down into Street View or fly to a particular angle on a 3D landmark.
While the release of Tour Builder was inspired by Google's work on projects like Map The Fallen and VetNet, it obviously has much broader application. Whether it's spicing up your typical vacation slideshow or building a presentation to teach students about the Civil War. Check out the video demo after the break.
