Drone surveying & photogrammetry in Le Mans
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.

€800–3,000 per day — the range observed on the 2026 French market, including regulatory preparation, flight and delivery. The exact quote depends on the site, the deliverable and the airspace context in Le Mans.
Common use cases
- Topographic survey of land ahead of a development or subdivision project
- Stockpile volume measurement in quarries or recycling platforms
- Centimetre-grade orthophoto of a municipality for its GIS
- Digital terrain model for hydraulic or flood-risk studies
- Erosion monitoring of riverbanks, dunes or coastal cliffs
- 3D modelling of a building or monument for a digital twin
The local context in Le Mans
Le Mans airspace revolves around the Le Mans-Arnage airfield, adjoining the 24 Hours circuit south of the city: during major races (car and motorcycle 24 Hours), temporary flight restrictions are systematically published and the airspace closely watched. The rest of the year, the dense city and Plantagenet quarter call for the built-up-area scenario with Sarthe prefecture notification.
Local demand blends heritage — one of Europe's best-preserved Roman walls, Saint-Julien cathedral with flying buttresses spectacular from above — the automotive and insurance industries (MMA), university and hospital construction monitoring, and of course the circuit ecosystem: testing, filming and team communications outside race periods.
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 Le Mans?
Almost: Aérodrome Le Mans-Arnage et circuit des 24 Heures; ZRT temporaires lors des grandes épreuves; Cité historique dense (scénario agglomération). Depending on the exact location, the pilot picks the right framework (open or specific category) and files the required declarations — included in the quote.
