John Snow’s 1854 Cholera Map comes to life with the CartoDB platform
February 9th, 2012 by Susan Smith
John Snow created a map of a cholera outbreak in the district of Soho, London in 1854, which helped to convince authorities that the disease was caused by water ( in particular, it originated from one pump in Broad Street). The CartoDB platform allows you to map data and develop location aware applications very easily. This example of John Snow’s Cholera Map of London presented with CartoDB demonstrates how CartoDB can quickly combine different data types, then display them on a map.
To see John Snow’s original map using the Google Maps zooming and panning tools then go to Hypercities.
A Google Maps mashup of historical maps available for many of the world’s cities, Hypercities allows the user to navigate a selection of historical maps using the familiar Google Maps navigation tools. If you zoom into London on Hypercities you can choose to view John Snow’s map overlaid on top of the modern map of London.
