You can navigate through the posts using the Google Earth application.
1. Open Google Earth
2. I suggest disabling all the layers, so as to obtain a “blank” surface of the planet, without modern overlays
3. Open the LostWorld.kmz file. You can download the file from the Dropbox “Public” directory at this address
4. You should now see the Lost World directory under “Temporary Places” in Google Earth. You can select the historical period that you want to show on the Earth surface.
6. When you’re done, close the Google Earth application and don’t save the LostWorld.kmz file: since it will be updated frequently, you need to download and open it again next time you want to use it
