250 years of change in Beijing revived with maps and photographs.
Old Beijing Landscape
To revive the old landscape of Beijing, we placed old photographs of Beijing using Google Earth KML. Google Earth has a function called "Photograph Overlay" that allows users to place photographs considering the direction of a camera which can be adjusted by viewing the virtual finder of a camera. We can see the same building from multiple viewpoints using multiple old photographs, so this is a useful tool for think about the old landscape.
