Mapping & Crowdsourcing

MAPPING

Why use mapping? One good example: it allows one to see things from a different perspective. Epidemiologist John Snow tracked cholera outbreaks in London, showing that an outbreak in the mid-1800s could be traced to a contaminated water pump.   Without the map, he’d have been faced with a long list of addresses where outbreaks occurred; with the map, he could immediately see where there was a real concentration of cases and hence where to investigate.
