If you are interested how you can use data from old maps, how interesting a history lesson can look, we recommend this short video.
It shows how America’s cities have grown for the last 200 years, before railroad and when it was built.
This film largely presents the tool and its possibilities, I personally missed the actual history that could be hidden behind this data. Anyway, I love statistics and the display of such possibilities was very impressive for me.
