Drone surveying & photogrammetry in Saint-Nazaire
Drone photogrammetry turns a few hundred aerial photos into precision survey products: georeferenced orthophotography at 1–3 cm/pixel, digital surface and terrain models, 3D point clouds, contour lines, stockpile and earthworks volume calculations. With an RTK/PPK drone and ground control points measured by centimetre-grade GNSS, accuracy reaches 2 to 5 cm both horizontally and vertically — sufficient for most development studies, at a fraction of the cost of an exhaustive ground survey.
We cover from 1 to several hundred hectares per day depending on the required resolution, including hard-to-access sites: working quarries, landfills, riverbanks, industrial wasteland. Deliverables come in your coordinate system (Lambert 93 / RGF93, conic conformal projections) and standard formats (GeoTIFF, LAS/LAZ, DXF, GIS formats). Chartered surveyors, civil engineering offices, quarry operators and local authorities are regular clients.

The local context in Saint-Nazaire
Saint-Nazaire is one of France's great maritime-industrial cities: Chantiers de l'Atlantique builds the world's largest cruise ships here, Airbus Atlantic assembles aircraft sections, and the Nantes-Saint-Nazaire seaport stretches to Montoir. Direct consequence for drone pilots: these industrial and port areas are no-fly zones, as is the WWII submarine base, and Saint-Nazaire-Montoir aerodrome (LFRZ) adds its own constraints to the north-east.
Outside sensitive zones, the city offers the Saint-Nazaire bridge (3,356 m over the estuary), the rebuilt seafront, beaches and the coastal path towards Pornichet. The local drone market is heavily industry-driven: monitoring of shipyard and offshore-wind projects (the Saint-Nazaire wind farm was France's first), structural inspections, thermal surveys of industrial roofs — missions that almost always require access protocols negotiated with site operators.
Applicable regulations
Survey flights mostly take place outside built-up areas, in open category A2 or A3 (photogrammetry drones weigh 900 g to 6 kg) flying automated grid patterns below the regulatory 120 m. Long corridors or populated sites fall under the specific category (STS-01/STS-02, or an operational authorisation for BVLOS on long corridors). The operator is registered on AlphaTango and checks regulated zones on Géoportail: quarries and industrial estates are often near airfields or under military low-altitude training routes (RTBA), requiring protocols or time slots. Legally binding georeferencing (enforceable boundary plans) remains the exclusive remit of chartered surveyors, with whom we work as subcontractors.
Frequently asked questions
What accuracy can a drone survey guarantee?
With an RTK drone and ground control points, we guarantee 2 to 5 cm XYZ accuracy, verified against independent checkpoints whose residuals are documented in the processing report.
Does a drone survey replace a chartered surveyor?
No for legally binding documents (boundary demarcation, land division): that is the chartered surveyor's legal monopoly. Yes for technical studies: our deliverables feed directly into civil works design, volume calculations and environmental studies.
Does vegetation interfere with photogrammetric surveys?
Yes: photogrammetry measures the visible surface, so the canopy rather than the ground beneath. For wooded areas, we offer drone LiDAR, which penetrates vegetation and reconstructs the bare terrain.
Can this service be flown anywhere in Saint-Nazaire?
Almost: Zones interdites des Chantiers de l'Atlantique et du port de Montoir; Aérodrome de Saint-Nazaire-Montoir (LFRZ); Base sous-marine et installations portuaires sensibles. Depending on the exact location, the pilot picks the right framework (open or specific category) and files the required declarations — included in the quote.
