The field of public health is one that has benefited greatly from technology related to GIS. A very famous early example of use of maps to combat a public health problem is when John Snow mapped the outbreak of Cholera in England during the 1850's. The ideas used by John Snow have been greatly enhanced in the nearly two hundred years since his innovative use of maps.
