Question

How are 'Geographical Information Systems (GIS) and Remote Sensing' utilized in disaster response?

• A. For managing financial donations and volunteer registration.
• B. For creating historical archives of disaster events.
• C. For damage assessment, resource mapping, and logistical planning.
• D. For developing new communication protocols for emergency services.

Answer 1

Answer:

C. For damage assessment, resource mapping, and logistical planning.

These technologies are crucial for providing a real-time, comprehensive view of a disaster-affected area.

• Damage Assessment: By comparing pre-disaster satellite or aerial images with post-disaster images, GIS and remote sensing can quickly identify the extent of damage to buildings, roads, and other critical infrastructure. This helps response teams understand the scale of the disaster and prioritize their efforts.

• Resource Mapping: GIS allows authorities to create interactive maps that show the locations of emergency shelters, hospitals, food distribution centers, and other vital resources. This helps in efficiently directing relief supplies and medical aid to the areas that need it most.

• Logistical Planning: These tools are used to identify safe evacuation routes and plan the movement of rescue teams. By integrating real-time data on road closures, flood levels, or debris, they help create the most efficient and safe pathways for response teams to reach the affected population.
