A challenge we will come up against is getting everything at the right scale. How large should the world map be relative to the size of each photo? Should photos that are more important be larger? How will we get an accurate scale relation between different models (for example, the La Perouse area model and landmark models such as the Museum and Tower)?

If one tends to stay put while wearing an Autograher, the resulting 3D spatial representation of the images gets much harder to view and interpret. If we’re going to make some kind of narrative, it will either have to be continuously moving or we will have to find a way to expand the close together data
