Original Summary

I read an article couple of years ago in a newspaper where they segmented one city based on how many schools, supermarkets hospitals etc were available in a certain area and then made a ranking based on that. The idea was mulling on my mind for a while and i finally got around making it not only for Tokyo, but for whole Japan!<p>Basically I gathered tons of different data sources from both freely available sources, Japan government&#x27;s own open census data etc, laid them on top of the map of Japan and created weighted scores based on the results. Then based on the user&#x27;s preferences (like do they want to see areas good for families, people living by themselves, do they use a car etc) it colours the map on 100m*100cm grids based on how good they are based on the values. Really good if you are for example trying to figure out a good place to live in a neighborhood and want to get a place that has a good access to supermarkets etc or even traveling a trip to the country :)
