Drone services in Nouvelle-Aquitaine: vineyards, forest, coastline, industry and prices

In Nouvelle-Aquitaine the question is almost never "can we fly?" — that is the Paris region's problem, not this one. Here the question is distance. At roughly 84,000 km² across twelve départements, it is the largest region in mainland France: between a Médoc estate, a maritime pine block south of Mont-de-Marsan, an oyster park in the Arcachon basin and a logistics roof in the Vienne, there are hours of driving. On a territory that size, a badly built quote mostly invoices travel. A well-built one groups several sites into a single tour, times the flights to the right agronomic or weather window, and drives the unit cost down. This guide reviews what a drone genuinely brings to the region's major sectors — vines, forest, coast, industry — what it does not replace, and how prices are built.

The largest region in France: what distance does to a quote

Nouvelle-Aquitaine covers roughly 84,000 km² and twelve départements, from the Vienne to the Pyrénées-Atlantiques and from the Charente-Maritime to the Creuse: it is the largest region in mainland France, bigger than Austria. In practice, a contractor based in Bordeaux is more than two hours' drive from Poitiers, Limoges or Bayonne. For a one-hour flight, travel then weighs more than the service itself — and that is the main reason quotes for the same need vary so much.

Hence a simple rule: think in tours, not in isolated call-outs. A wine group mapping six estates spread between Blaye, Libourne and Bergerac; a local authority surveying three roofs, a stadium and a business park; a forest manager lining up four stands to inventory in the same district — in all three cases the unit price falls because travel, administrative preparation and flight-file work are shared. The travel charge beyond a 30 to 50 km radius still applies, but it is divided by the number of sites.

A second consequence: the flight window becomes a planning parameter, not a detail. Multispectral vine mapping needs a precise growth stage and clear skies, a dune survey follows a storm, a thermal roof flight happens at first light. On a territory where you cannot come back the next day for free, it pays to offer several possible dates and a fallback date at order stage — that is what avoids paying for a cancelled trip.

South-West airspace: control zones, airfields and military areas

The region does not have the Paris area's air traffic density, but it has its own locks. The first is the Bordeaux-Mérignac control zone (CTR), a joint civil and military platform covering much of the Bordeaux conurbation: any mission inside that perimeter goes through a protocol with air navigation services, with a lowered ceiling and a negotiated slot. Then come the zones attached to the airfields of Pau-Pyrénées, Biarritz-Pays Basque, Limoges-Bellegarde, La Rochelle-Île de Ré, Poitiers-Biard, Bergerac-Dordogne-Périgord or Brive-Vallée de la Dordogne: lighter constraints, but real ones as soon as you approach an approach path.

The South-West's specificity lies elsewhere: the density of military and test ranges. Mont-de-Marsan air base 118, Cazaux air base 120, the Landes site of DGA Essais de missiles at Biscarrosse — the only European centre able to flight-test very long-range missiles — and the Captieux firing range, some 9,000 hectares attached to the Mont-de-Marsan base, form a complex that shapes the airspace of the Gironde and the Landes. Add zones linked to sensitive installations (the Blayais and Civaux nuclear sites, defence establishments) and coastal nature reserves whose own rules usually prohibit low-level powered overflight.

The practical consequence: in Nouvelle-Aquitaine, zone analysis is done at the exact address, not at commune level. Two neighbouring plots can fall under different regimes, and a test range may be active on certain days only, which makes checking temporary restrictions the day before the flight essential. For missions inside a CTR or near an airfield, our guide to drone missions in a CTR and airfield protocols details the procedure and lead times.

Viticulture: Bordeaux, Cognac and Bergerac

The region concentrates France's largest wine-growing complex: the Gironde remains the country's leading wine département with around 90,000 hectares after several grubbing-up campaigns, the Cognac vineyard covers a comparable order of magnitude across the two Charentes, and the Bergerac area completes the picture in the Dordogne. At that scale, the drone is not a communication gadget: it is a field sensor. A multispectral flight produces a per-vine vigour map used to zone a block, prepare selective harvesting or explain a yield gap. A very high resolution RGB flight counts missing vines row by row — a figure worth knowing before any replanting or estate purchase negotiation.

The other uses follow the calendar: thermography to spot water-stress zones in summer and the cold spots that signal spring frost risk, health monitoring to map the spread of dieback clusters year over year, topographic survey to size a drainage scheme or a planting project. The literature confirms the value of these maps: Massimo V. Ferro, Pietro Catania and their co-authors, in a study published in 2023 in Biosystems Engineering, tracked a commercial vineyard at three phenological stages with a multispectral drone and showed that the resulting vegetation indices capture spatio-temporal variability in vigour and yield that is usable for block management (see the study on Google Scholar).

Then there is the question of flying over property, a sensitive one in a vineyard where blocks interlock. The working principle is clear: the mission is ordered or authorised in writing by the operator, who provides the ground access needed for take-off and safety, and the deliverable is clipped to the commissioned perimeter — identifiable neighbouring plots do not appear. The same discipline applies to communication imagery, where the neighbouring château should not feature without agreement. These services fall under our drone agriculture and viticulture offer, and are easily run from Périgueux or Bordeaux depending on the sector.

The Landes de Gascogne forest: inventory, health, windthrow and fire

The Landes de Gascogne forest — around one million hectares, overwhelmingly maritime pine, across the Gironde, the Landes and the Lot-et-Garonne — is Europe's largest planted forest, and predominantly privately owned. It is almost ideal drone terrain: flat relief, even-aged stands, geometric block layout. Common uses are inventory and health monitoring (heights, density, gaps, dieback), pre-sale volume estimation and post-planting survival checks.

Photogrammetric height measurement has been evaluated on this very forest: Raphaël Segura, Alexia Mathou, Laurent Bouffier and Céline Meredieu published in 2025 in NOV'AE a comparison, on Landes de Gascogne maritime pine, between conventional dendrometric measurement and 3D drone photogrammetry, with an average error of around 1% in the most favourable flight configuration and a slight systematic underestimation of heights (see the study on Google Scholar). In other words: accuracy comparable to ground methods, across the whole stand rather than a few plots — but a result that still needs calibrating against field measurements, and does not remove the need to walk the forest.

Two hazards dominate regional management. Storm windthrow first: a quick flight delivers the exact footprint of the gaps, guides salvage operations and documents the damage for insurance. Fire next: the summer of 2022 burned close to 30,000 hectares in the Gironde, between La Teste-de-Buch and Landiras, and left the sector demanding stronger surveillance. The drone plays three roles complementary to existing means: prevention patrols and smoke detection on high-risk days, reconnaissance support during an event when the authorities request it, and burn severity mapping afterwards to organise replanting. It replaces neither watchtowers nor firefighting aircraft: it covers blind spots and documents.

The Atlantic coast: dunes, shoreline, oyster farming and ports

With more than 700 kilometres of coastline, the region combines a rapidly retreating sandy coast with a more stable rocky Basque shore. Measurements by the Nouvelle-Aquitaine Coastal Observatory put average chronic retreat at around 2.5 metres per year in the Gironde and 1.7 metres per year in the Landes, against roughly 0.25 metres per year on the rocky Basque coast. At those rates, annual or post-storm monitoring is not a luxury: it is the basis of planning and relocation decisions.

The drone has established itself as the intermediate tier between beach profiles walked on foot and institutional airborne LiDAR campaigns. A regional reference demonstrated it early: Bruno Castelle, Richard Michalet, Stéphane Bujan and David Rosebery published in 2019 in the Journal of Marine Science and Engineering a low-cost photogrammetric method for monitoring the beach-dune system, applied at Truc Vert in the Gironde over roughly one square kilometre, with decimetre resolution and a survey frequency impossible to sustain with heavier means (see the study on Google Scholar). That is exactly the framework of our coastal erosion monitoring by photogrammetry service, supporting our surveying and photogrammetry offer.

Two other coastal sectors benefit from the same flight. Oyster farming first: Nouvelle-Aquitaine is France's leading shellfish region with the Marennes-Oléron and Arcachon basins, where drone-based farm monitoring allows tables to be inventoried at low tide, concession occupancy to be checked and damaged structures to be spotted without trampling the foreshore. Ports and maritime structures next: quays, breakwaters, riprap, pontoons and gantries at the ports of Bordeaux, La Rochelle or Bayonne can be inspected by drone between underwater surveys, with a photogrammetric record serving as the reference from one check to the next.

Industry and services: aerospace, wood and paper, food processing, logistics

Nouvelle-Aquitaine is one of France's leading regions for aerospace, space and defence, with several hundred establishments concentrated around Bordeaux-Mérignac, Saint-Médard-en-Jalles and the Pau area, home in particular to helicopter engine manufacturing. This industrial fabric generates classic but demanding needs: roof and cladding inspection on very large halls, hangar structure surveys, site extension monitoring, and above all thermography of flat roofs, heat networks and on-site photovoltaic installations. The local particularity is the frequent proximity of an airfield or a military area, which requires an upstream protocol — hence the value of planning these campaigns several weeks ahead.

The wood and paper sector attached to the Landes forest generates another kind of mission: volume measurement of log piles and wood chip stocks at sawmills and biomass plants, thermal surveys of piles to detect self-heating hot spots, timber yard monitoring after storms. Food processing — wines and spirits, seafood, poultry and vegetables — and logistics along the A10, A63 and A89 corridors complete the picture, with warehouse roofs of several hectares where a thermal and RGB flight beats an inspection from a cherry picker.

Two habits apply to all these sites: never order a flight without knowing what the deliverable will be used for — a usable inspection report beats a handsome orthophoto — and check the site's regulated-installation or explosive-atmosphere zoning before the mission, since it determines where the pilot can set up the take-off area. From Pau, Limoges or Bordeaux, these campaigns group easily by industrial basin.

Method, flight framework and prices

A regional mission always runs in the same order: zone analysis at the exact address (airspace, military areas, temporary restrictions, sensitive sites), choice of regulatory framework — most rural flights are handled in the open category, while flights in built-up areas, near uninvolved people or inside a CTR fall under the specific category with a declaration and, where relevant, an airfield protocol — preparation with the site (access, take-off area, safety instructions, written owner authorisation), then flight, processing and delivery. The applicable rules are those in force in August 2026; temporary restrictions are still checked the day before the flight, which matters particularly near the South-West test ranges.

Orders of magnitude observed in Nouvelle-Aquitaine in 2026 (excl. VAT):

Three limits to keep in mind: the drone does not fly in strong wind or sustained rain, which makes a fallback date necessary; it does not see under closed canopy without LiDAR, nor underwater; and it never removes the need for independent ground verification on high-stakes matters (inventory, expert appraisal, insurance claims). For a project in Nouvelle-Aquitaine, request a quote stating the exact addresses of every site involved and the target period: that is what makes it possible to build a tour and bring the unit price down.

Frequently asked questions

Do you charge travel across the whole of Nouvelle-Aquitaine?

Beyond a 30 to 50 km radius from the departure point, a travel charge applies, typically €0.50 to €0.80 per km, or a negotiated package for distant missions. That is exactly why every site involved should be declared up front: three interventions grouped over two days in the same area cost far less than three separate trips from Bordeaux.

Can you fly over a vineyard or forest that is not ours?

Flying over private property is not prohibited as such, but the mission must be ordered or authorised by the site operator: they grant ground access for take-off, safety and landing, and they alone can authorise use of imagery of their property. In practice we require written authorisation from the owner or manager, and we exclude from the deliverable any identifiable neighbouring plots outside the commissioned perimeter.

Can a drone replace our forest inventory or ground plots?

No, and no serious contractor will claim otherwise. The drone gives exhaustive coverage of a stand — heights, density, gaps, vigour — where conventional inventory samples a few plots, but it still needs ground measurements to be reliable. The right combination is an exhaustive flight plus a reduced ground sample used to calibrate and check the estimates.
