Study Notes
John Snow's Contribution to GIS
- John Snow used mapping to illustrate how cases of cholera were centered around a water pump.
- His work marked the start of epidemiology, the field of study that deals with the distribution and determinants of health-related events.
Mapping and Revelations
- Snow's mapping of outbreak locations, roads, property boundaries, and water lines revealed that the spread of cholera was related to contamination of water from a specific pump.
The Cholera Outbreak
- A major cholera outbreak hit London, England in 1854, leading to Snow's mapping of outbreak locations.
- Snow's work demonstrated Geographic Information Systems (GIS) as a tool for understanding the spatial distribution of diseases and identifying sources of outbreaks.
