"My only comment is in how you measure the value of an address." This. Having lived in the center (reddish area) and later also in southern Helsinki (bluish green), I strongly prefer the latter due to it's proximity to the sea and as it's way quieter area without busses, trams or general traffic. And judging by housing prices so do many others who live in the city. Don't get me wrong. I found the map highly interesting but maybe in determining best places to live it's a bit of a stretch. There might more value here for businesses that aim to be easily reachable.
