# Drones aid rescue in Gujarat floods with mapping and relief drops

In Gujarat’s floods, Prime UAV used drones in Dholka to map flooded areas, guide responders, and deliver food and water. The technology creates detailed maps from aerial images and can carry payloads to hard-to-reach spots, aiding search and rescue.

## Key takeaways

- In Gujarat, Prime UAV used drones to support rescue operations in Dholka during floods.
- Drones provided aerial surveillance, including at night, and delivered food and water to hard-to-reach locations.
- Imagery from drones is processed into orthomosaic maps to show flood extents and changing conditions.
- Advanced sensors like LiDAR and RTK GPS enhance terrain and position accuracy for planning and response.

## What Happened

The floods in Gujarat led rescuers to seek clearer information about flood extents and the location of people in need. In Dholka, a village near Ahmedabad, a Mehsana-based company named Prime UAV deployed drones to support rescue teams. The drones provided aerial surveillance, including operations conducted at night, and assisted in identifying areas where people required aid. They were also used to deliver food and water packets in waterproof payload boxes to locations that were difficult to reach by road.

Beyond live observation, the article describes how drone-derived data is transformed into actionable maps. Drones capture extensive imagery to produce an orthomosaic map, a detailed map created by stitching hundreds of overlapping photographs. Over time, repeated flights help responders track changes in flood dynamics, such as water spread and the accessibility of roads and areas.

The article notes that mapping and positioning technologies enhance the usefulness of drone data. Overlapping photographs are processed to identify common points and combine them into a single, georeferenced map. When additional sensors are used, such as LiDAR or RTK GPS, the resulting data can provide elevation details and more precise positioning. These capabilities help authorities understand terrain, drainage channels, embankments, and floodplains, informing both immediate response and planning for future events.

In the pre-disaster phase, aerial surveys can document infrastructure like rivers, bridges and drainage systems to establish baseline terrain and identify low-lying areas. During a flood, the same technology supports surveying large or dangerous zones, locating flooded roads, and guiding decisions about where to dispatch rescue personnel and supplies. Some drones may carry thermal cameras to detect heat signatures during search-and-rescue operations and enable payload delivery where access is limited.

Overall, the article emphasizes that the practical value of drones lies not just in flying over damaged areas, but in translating aerial imagery into maps and actionable guidance for rescue teams and relief efforts.
