Drone surveying & photogrammetry in Saint-Nazaire

Free quote — surveying & photogrammetry in Saint-Nazaire

Shoreline, port structures, land reclaimed from the Loire estuary: in Saint-Nazaire, drone photogrammetry delivers georeferenced orthophotos and 3D models, even over areas hard to survey on foot. From Pont de Saint-Nazaire to the outlying districts, our pilots know the terrain of Saint-Nazaire and prepare every flight on the local aeronautical chart.

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. 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.

Flying in Saint-Nazaire: the local framework

A photogrammetric survey in Saint-Nazaire covers the site in parallel flight lines: inside the restricted perimeter (Zones interdites des Chantiers de l'Atlantique et du port de Montoir), the authorisation must describe that grid precisely — a technical file we prepare as standard.

Photogrammetric surveys fly in the open category over controlled sites, on automated grids below 120 m; urban footprints or sites crossed by third parties move to the specific category with a declaration. Full regulations and rates: surveying & photogrammetry across France →

With GNSS-measured ground control points, the orthophoto and point cloud reach 2–5 cm planimetric accuracy — enough for a preliminary design survey. For legally binding documents we work under a partner chartered surveyor covering Pays de la Loire.

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.
