A very interesting project indeed. The most interesting part lies in the the subject itself (so interesting in terms of history and culture) and the way it has been computerised.
Just a question : is it an aerial visit (balloon, plane, helicopter...) or does it consist in different snap shots taken from Google Earth ? Or from another satellit ?
Whatever your answer, I like it. But I think you can make it still more interesting (hotspots..., descriptions...)
Congratulations,
