Chapter Content
• UAVs deployed to assess flood extent and infrastructure damage
Detailed Explanation
Unmanned Aerial Vehicles (UAVs), commonly known as drones, were used to fly over the areas affected by floods in Kerala. Their primary purpose during this disaster was to evaluate how widespread the flooding was and to determine the level of damage to various infrastructures like roads and buildings. This assessment was crucial for planning effective responses and aid distribution.
Examples & Analogies
Imagine a firefighter using a drone to visualize the extent of a fire in a forest. Just as the drone helps the firefighter see which areas are affected and which are safe, UAVs in Kerala provided a bird's-eye view of the flooding, allowing responders to prioritize their actions.
Use of Thermal Sensors

Chapter Content
• Thermal sensors helped locate stranded individuals
Detailed Explanation
The drones were equipped with thermal sensors, which can detect heat signatures from living beings even in difficult conditions, such as heavy rain or darkness. These sensors were vital in identifying individuals who might be trapped or stranded due to the floodwaters, ensuring targeted rescue operations could take place efficiently.
Examples & Analogies
Think of a thermal sensor like a heat-sensing camera that can find someone hiding in the dark. Just as such a camera could reveal where that person is based on their body heat, the drones in Kerala used thermal sensors to find people in distress, making rescues faster and saving lives.

• Enabled quick response and rehabilitation planning
Detailed Explanation
The information gathered by the drones allowed authorities to quickly understand the scale of the disaster and plan for rehabilitation efforts accordingly. By having real-time data on the extent of the damage, disaster response teams were able to strategize efficient distribution of resources, assistance, and how to rebuild affected areas.
Examples & Analogies
Consider how a doctor uses a scan to diagnose a patient quickly. The scans provide immediate insights on what needs to be treated. Similarly, the data from the drones acted like a diagnostic tool for the government and aid organizations, helping them to determine where to focus their recovery efforts most urgently.
