The re-elaboration of John Snow’s map in a GIS environment. Input for transferring methodological and applied skills being inspired by a virtuous practical example of social utility
John Snow’s map made it possible to save many human lives by interrupting the spread of cholera, in an area of London in 1854 after the study of a relevant number of cases which allowed him to put his assumptions and research into practice. His work had a crucial role for future developments of epidemiology and provided the basis for (geo)spatial discussions and density studies in relation to risk factors and his insights enabled cartographic and successively GIS approaches, as support to medical studies, to have remarkable advances.
