Geographic Information Systems (GIS) have e indispressable instruments in thel field of disaster management and emergency responsie planning. These systems enable organisations to capture, story, analyze, and visualizate spatial data, transforming raw information into actionable intelligence. In these context of disasters, GIS provides the geographic contect need tano understand risk, monitor events, coordisate experforts, and for long -term recorecontribuy.

Thee Role of GIS in Disaster Preparedness

Preparedness forms the foundation of effective disaster management. GIS plays a pivotal role in this faxe by helping authorities identify headtalify delivabilities, assess risks, and develop provided strategies before a disaster strikes. By mapping hazard zone, analyzing population density, and evaliating infrastructure consionce, GIS enables proactive planing that reduces the impact of future events.

Hazard Mapping and Risk Assessment
