How SDIS 83 Uses Drones To Combat Wildfires In Southern France

In the rugged, drought-prone terrain of southern France, the response to wildfires is evolving fast. The SDIS 83 (Var Fire and Rescue Service) has placed drones at the heart of its strategy to stay one step ahead of rapidly spreading blazes. This case study explores how their aerial intelligence unit operates, the technology in play, and what professional drone operators in the UK can learn from this pioneering public safety application.

The challenge Of Wildfire In Var

Wildfires in the Var department can escalate in minutes. Steep slopes, dense scrub and hot, dry winds create a volatile mix. For operational command, the first moments matter. At the department’s operational centre, handling over 120,000 interventions a year and some 1,300 calls a day, the pressure to deploy the right resources fast is relentless.

In this environment the drone team functions as an intelligent unit for the incident commander, providing rapid, accurate situational awareness that traditional ground units simply cannot match in terrain or speed.

A Dedicated Drone Team Operating Round The Clock

SDIS 83’s drone unit is staffed by 30 certified pilots, embedded year round and available day and night. At the reception of a wildfire call the operations centre assesses the urgency, mobilises both ground and aerial units, and dispatches the drone squad as a priority.

From launch to live intelligence updates, the drone becomes a critical asset, not simply as a camera on a stick but as a high-value sensor suite that supports decision-making, safety monitoring and tactical coordination.

Real-Time Surface Area Calculation, Mapping & Hot Spot Detection

On deployment the drone scans the fire zone and calculates the surface area in real time. The team receive a colour-coded map that clearly shows the zone they are dealing with. This instant computation enables operations command to size up the incident quickly so that appropriate resources, such as fire engines, water drop units and containment lines, can be allocated precisely.

Once the area is visualised the next step is to locate hot spots. Using a thermal camera combined with a laser rangefinder capable of measuring up to about 1,400 metres, the drone identifies heat signatures beyond the line of sight of ground teams. That range-finding is important. It supplies the exact distance from drone to hot spot, which allows ground units to navigate precisely to residual fire risk. A photo of the scene is then sent to the command centre (CODIS) and incident commander so that everyone shares the same, accurate view.

Elevating Safety, Efficiency & Coordination

What does this mean in practice for the firefighting operation? First, the aerial view reduces risk for those on the ground. Instead of having boots on the ground venture into unknown terrain, the drone scouts ahead and flags active hot zones, embers still burning and inaccessible terrain.

Second, resource allocation becomes smarter. With area mapping and hot spot identification in hand the incident commander knows how many crews, water resources and aerial units to deploy. That prevents over commitment or under deployment.
Third, coordination improves. The image feed, map overlays and real-time data mean that ground teams, command staff and aerial units are all working from the same set of facts. In emergency operations that shared situational awareness is a major force multiplier.

Lessons For UK Professional Drone Operators & Emergency Services

For UK professionals operating drones in the public safety or service sector, SDIS 83’s model delivers a number of actionable takeaways:

• Round the clock readiness counts. Having drone pilots available continuously ensures that aerial intelligence is not a nice to have but a core capability.
  
• Sensor sophistication is key. Thermal imaging, laser rangefinding and real-time mapping matter. The hardware must be purpose built for emergency operations.
  
• Data integration is critical. It is not enough to fly a drone. The data must feed seamlessly into the command centre workflow. That means compatible software, live feeds, image annotation and common operating pictures.
  
• Training and procedure matter. Pilots must operate within the incident command structure. Clearly defined roles, standard operating guidelines and integration with ground crews are essential.
  
• Mapping and measurement deliver value. Beyond capturing nice visuals, the drone must compute areas, overlay imagery and support tactical decisions. That ability separates a flyer from a mission critical asset.
  
• Safety and compliance leadership. UK operators must be aligned with CAA frameworks, risk assessments, RPAS rules and public safety coordination protocols. Learning from a high-stakes wildfire environment encourages rigour in operational safety.

Technology Spotlight

In this case the drone unit uses a laser rangefinder (with approximately 1,400 metre range) combined with thermal and visual cameras. It performs live surface area calculations and overlays them onto maps for rapid decision making. These are not off the shelf consumer toys but enterprise grade systems designed for public safety outcomes. For UK businesses and emergency services looking to replicate this model, the key is selecting a platform with:

• High sensitivity thermal imaging for hot spot detection
  
• Long range laser range or LiDAR for accurate distance measurement
  
• Advanced mapping or photogrammetry software enabling real-time area calculation and colour overlays
  
• Secure live feed capabilities and integration with command centre systems
  
• Robust build for outdoor and harsh environment operations

Strategic Impact

SDIS 83’s use of drones represents a transformation in wildfire response. They move from reactive to proactive. Drones give them eyes on the fire ahead of ground crews, they reveal hidden risk, they support efficient resource deployment and they ensure safety. For professional drone operators in the UK this is an invitation to shift not just hardware but strategy. Drones should not sit in the back of the fire engine. They should plug into operational workflows and incident command systems. In a service business or public safety organisation, the ROI comes in saved time, reduced risk and better mission outcomes.

From a market perspective, this positions drone service providers and integrators as strategic partners in emergency response, not simply versus a one off inspection job. The relationship becomes one of operational readiness, data intelligence and multidisciplinary coordination.

Challenges & Considerations

There are operational challenges to consider. Terrain and weather vary. Night operations introduce complexities for flight paths, lighting and visual line of sight. Regulatory compliance and airspace coordination remain central in the UK. Organisational buy in is needed. Command staff must be comfortable using drone data for decision making. And technology reliability under stress is essential. Batteries, signal integrity and sensor calibration all impact mission effectiveness.

Finally, data handling and security must be addressed. Aerial intelligence dealing with critical incident zones may involve sensitive imagery, requiring robust communications, encryption and data management protocols.
