The PHIMS tool is a GIS application that allows for real-time surveillance of various environmental and demographic data. PHIMS displays the data as layers on virtual maps as they relate to specific regions in Ontario, and the tool can be accessed through a web-based user interface. Users can visualize their map from several basemaps and apply colour-coded layers. Environmental layers help to predict and prepare for emergencies and to track weather events. Additionally, PHIMS enables users to determine where the most vulnerable populations reside so that they can prioritize resources during an emergency situation.
