So what is Tour Builder? Tour Builder uses Google Earth technology and allows you to add a sequence of locations on a map that users can click through like they’re going on a tour. You can upload up to 25 photos and YouTube videos to go along with each stop on the tour. You can also add a description and links to additional resources for each location that you add. When users view the Tour, they will click “next” on the tour to be taken to the next point on the map.
