Drone surveying & photogrammetry in Niort
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 Niort
Prefecture of Deux-Sèvres, Niort is the French stronghold of mutual insurance: MAIF, MACIF, MAAF and SMACL are headquartered here, making the city the country's fourth financial centre. Heritage clusters around the twin Romanesque keep, the Baltard-style market halls and the green corridor along the Sèvre Niortaise. To the west opens the Marais Poitevin, France's second-largest wetland: its nature-reserve sectors and Natura 2000 zones call for overflight precautions, especially during nesting season.
Niort's economy blends insurance services, digital risk-management, food processing and river tourism in the "Green Venice". Sought-after drone services: corporate communication for head offices, commercial real estate, construction monitoring, tourism imagery of the marsh punts and agriculture over the cereal plain.
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 Niort?
Almost: Zones protégées du Marais poitevin (réserve naturelle, Natura 2000); Aérodrome de Niort-Marais poitevin (LFBN). Depending on the exact location, the pilot picks the right framework (open or specific category) and files the required declarations — included in the quote.
