London, 1854. Difficult times for London population, specially in Soho, when a cholera outbreak killed thousands. A map saved the city. How?
By mapping the deaths in a street map and adding the location of water wells, John Snow found out the relation between a contaminated water source and cholera. It was an instant insight, driven from spatially organized data, prepared to be seen in a map.

This is one of the most inspirational use of maps and location analytics in history. The outcome allowed to save lives and, to some extent, to define the future of cities as we know them.
