Geographic Information System (GIS) technology is essential for risk identification, action prioritization, and resource optimization in critical situations like flooding and earthquakes. By integrating spatial and demographic data, GIS provides a comprehensive framework for emergency response.

GIS integrates data layers, like rainfall intensity, topography, elevation profiles, and river levels, to model high-risk flood zones. These layers assess areas susceptible to flooding based on their proximity to rivers, drainage systems, and low-lying regions. This approach allows emergency planners to identify vulnerable areas and develop strategies for risk mitigation.

GIS analyzes critical factors such as population density, accessibility to safe zones, and the location of vulnerable communities. By mapping potential evacuation routes and emergency shelters, GIS ensures rapid and organized population movement during emergencies. 

GIS-generated thematic maps visually display flood extents, road closures, and ongoing rescue operations during a flood event. These maps help decision-makers allocate resources effectively, by ensuring that medical aid, relief supplies, and rescue teams reach the most critical areas. 

GIS plays a key role in post-disaster recovery. Damage assessment maps highlight areas that require urgent attention, providing measures for debris removal, infrastructure repair, and community rebuilding. By prioritizing recovery activities, GIS supports the efficient restoration of affected regions and reduces the long-term impacts of flooding.
