Résumé :
|
In many countries, public health mapping and GIS are already being used to locate the geographical spread of diseases and populations at risk, identify unmet health needs, and target the delivery of health interventions such as medicines, vaccines, drinking-water filters, or mosquito nets. The visualization of geographically linked information from a wide range of different sources offers fresh insights, increased responsiveness, and greater precision in efforts to improve public health. Each map can then be overlaid onto any of the other maps, as required, creating kaleidoscopic layers of linked information which can be analysed to support decision-making.
