The data is an impression collection, I make no doubt about that. The years attached to the video are just inaccurate. That seems like sloppy work after all the great work was done. Moreover, as pointed out in another post, this is from a piece of software called CENTENNIA Historical Atlas: http://www.clockwk.com/ http://www.clockwk.com/ Which I would be getting right now, if it had a Linux version. The reason I complain about the years and the maps not matching is that they are doing a disservice to the people who have collected all this data. http://www.youtube.com/watch?v=ZRGKhnn-SWw http://www.youtube.com/watch?v=ZRGKhnn-SWw << Looking at this video, I get a sense of how impressive the data collecting is. Awesome I say. Much more interesting than the timelapse video.
