Cholera deaths in Soho, London, 1854: Risk Terrain Modeling for epidemiological investigations.

Risk Terrain Modeling (RTM) is a spatial analysis technique used to diagnose environmental conditions that lead to hazardous outcomes. Originally developed for applications to violent crime analysis, RTM is utilized here to analyze Dr. John Snow's data from the 1854 cholera outbreak in London to demonstrate its potential value to contemporary epidemiological investigations.

Is counter-terrorism policy evidence-based? What works, what harms, and what is unknown.
