Drone surveying & photogrammetry in Saint-Brieuc

Shoreline, port structures, land reclaimed from the Bay of Saint-Brieuc: in Saint-Brieuc, drone photogrammetry delivers georeferenced orthophotos and 3D models, even over areas hard to survey on foot. From the town centre to the business parks, the pilots covering Saint-Brieuc and its department (22) match equipment and flight plan to each order.

The local economy relies on agri-food (Le Gouessant, slaughterhouses and cooperatives), the Légué port at the head of the bay and departmental services. The Art Rock festival animates the city every spring. Typical drone missions: structure inspection (viaducts), construction monitoring, port and bay imagery (outside the reserve), vegetable farming and agri-food communication. Prefecture of the Côtes-d'Armor, Saint-Brieuc clings to a plateau carved by the Gouët and Gouédic valleys, spanned by viaducts — a singular urban relief from the air, around the fortress cathedral of Saint-Étienne and half-timbered lanes.

Flight rules in Saint-Brieuc

A photogrammetric survey in Saint-Brieuc covers the site in parallel flight lines: inside the restricted perimeter (Réserve naturelle nationale de la baie de Saint-Brieuc (survol à basse hauteur interdit)), 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 →

Frequently asked questions

Surveying & photogrammetry in Saint-Brieuc: what budget should you plan?

Allow €800–3,000 per day — the 2026 French market range, including regulatory preparation, flight and delivery. Build the overflight-authorisation lead time for Saint-Brieuc into your schedule: several weeks depending on the case.

What accuracy can a drone survey achieve in Saint-Brieuc?

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 Bretagne.

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.
