Drone 3D site models for fire emergency plans (POI, ETARE in France): method, prices
When fire breaks out on an industrial site, the first decisions are made on a plan: where to commit resources, where the hydrants are, what sits behind that cladding, where the hazardous storage is. Yet the drawings attached to French sites' internal emergency plans (POI) and to fire services' pre-planning files (ETARE) often run ten years behind the ground truth: extensions, relocated racking, blocked access routes, vegetation. The drone brings the plan up to date — high-resolution orthophoto, oblique facade views, measurable 3D model — turning a regulatory document into an operational tool, for the annual drill and for the real night-time response alike.

The observation: regulatory plans, rarely operational ones
French sites subject to internal emergency plans, logistics warehouses and establishments pre-planned by the fire service share the same Achilles heel: the site mapping. The block plans in the files date from the building permit; available aerial photos are national survey imagery, sometimes years old and never at the scale of useful detail (a gate, a valve, a hydrant). During the drill — and worse, during the incident — gaps between plan and ground cost minutes: a blocked fire access, a forgotten ladder pad, a water reserve unfindable at night.
The drone's contribution to emergency management has been documented for a decade: Ágoston Restás, in a 2015 synthesis in the World Journal of Engineering and Technology, classified applications by phase — before, during and after the disaster — and stressed the value of upstream cartographic preparation, the least spectacular but most cost-effective of all (see the study on Google Scholar). That is exactly this mission's purpose: preparing, not overflying the fire.
What the drone delivers: the emergency plan's visual layer
The typical mission produces four complementary deliverables:
- The high-resolution orthophoto of the site and surroundings, georeferenced, onto which the plan's layers are drawn: access routes and traffic directions, ladder positioning areas, firefighting water points, isolation valves, firewater containment areas.
- Oblique views of every building's facades — what the incident commander will actually see on arrival, by day as the night-time reference.
- The measurable 3D model: building and outdoor rack heights, distances between storage areas, road clearances — the basis of a site digital twin if the operator wants to go further.
- GIS and PDF exports that drop straight into the emergency plan, the fire service's pre-planning file and drill materials.
Capture takes one or two days, coordinated with operations — our guide to hosting a drone mission on an industrial site describes the standard framing (prevention plan, ATEX zones, time slots).
The uses: drills, responders, insurer
The same visual base serves three audiences. The operator: emergency drills get more realistic when prepared on real site imagery — localised scenarios, routes timed on the orthophoto, second-response team briefings on the oblique views. The fire service: an illustrated, current pre-planning file shortens reconnaissance; some French fire services now explicitly ask for recent aerial views of high-stakes sites. The insurer: up-to-date mapping of storage, separation distances and defence resources feeds the risk survey — the same flight often serves both files, as our guide to drone surveys for property risk prevention details.
Updating is the real issue: a living site keeps changing, and it is the year-on-year comparison that keeps the plan reliable. In practice one refresh per year — or after each notable modification — is enough, at a cost well below the initial flight. Sites wanting to go beyond preparation can add early detection patrols or thermal monitoring of high-risk storage.
2026 prices
Orders of magnitude observed in France in 2026 (excl. VAT):
- Site under 10 hectares (orthophoto + oblique views + exports): €1,800 to €3,500.
- Site of 10 to 50 hectares with 3D model: €3,000 to €6,000 depending on building complexity and GIS deliverables.
- Annual refresh (same footprint, comparison with the existing model): 40 to 60% of the initial price.
- Drill coverage (aerial video of the emergency exercise for the debrief): €800 to €1,500 per half-day, poolable with a refresh.
For a site subject to an internal emergency plan, the budget compares with a single avoided hour of production stoppage — usually the argument that convinces management.
