Below is an embedded Google Earth KML tour which introduces some features of KML tours. It includes a two minute flying tour with audio narration.
The controls at the lower left of the tour window can be used to stop and start the tour, and when the tour is stopped you can navigate around the landscape and view the photos and gigapans. The links within the gigapan popups are not a good way to view gigapans.
Click here to open the KML tour in a new browser tab. Then click the “Play Tour” button (upper right) to start the tour. (Note: If you enter a gigapan, the “Exit Photo” button is partly hidden under the “Terrain” button. Click the exposed edge of it to exit the gigapan.)
If you have Google Earth installed, you can download the KMZ file here, and play the tour full screen and interact with the drawn features or included media.
