This week we studied at the GIS application on every level of the firefighting. First, GIS could be applied to municipal firefighting prevention and response by visualizing the geospatial information in an emergency. GIS can also be used to make a decision on the best location of a fire station. It can also work for a pre-incident survey to give respondents a better idea of what they will encounter when entering a building. Fire hydrant maintenance needs GIS tool as well to mark exact locations of fire hydrants. Besides, the emergency planning such as first responders and fire chief, and the wildfire management including planning and analysis and field operations are all related to GIS techniques.
