Welcome to Spatial Health Analytics

Spatial Health Analytics is a public health geomatics company that utilizes geospatial tools and methods to assess public health phenomena. Our core tools are geographical information systems (GIS), remote sensing , spatial statistics, and data management. The health of populations is influenced by the world around us and spatial analysis is arguably the best way to measure the interactions between populations and the spaces in which they live and work. Perhaps the most famous example of spatial analysis for public health was Dr. John Snow’s 1854 investigation into the source of the Cholera outbreak in London. By plotting the cases on a map he found that they centred around a single water pump. He removed the pump handle and the outbreak ended, thus not only did he stop the outbreak, but also provided evidence to his theory that Cholera was spread through contaminated water.

Since that time spatial analysis has been used in the field of  public health to identify spatial patterns of chronic and infectious diseases. It has been used to identify habitats of vectors of disease such as mosquitoes that can spread diseases such as malaria, dengue, and West Nile virus. It has also been used to plan health services such as where to locate new hospitals, the routing of EMS, the planning of early childhood centres, and where to put vaccination clinics. Spatial analysis has also been used to identify variations over space and time in cancer registries, and even to quantify how climate affects health outcomes.

Maps are widely used in spatial analysis and also provide an easily interpreted medium to disseminate complex information to a wide audience. Spatial statistics can be used to quantify relationships between potential causes of negative health outcomes and actual human populations. However, the main strength of spatial analysis is found in the ability to link a wide range of information based on a common trait, namely location. At Spatial Health Analytics we specialize in using spatial information to understand and quantify the relationships between the environment and people.
