Drone surveying & photogrammetry in Brest

Free quote — surveying & photogrammetry in Brest

Shoreline, port structures, land reclaimed from the Brest roadstead: in Brest, 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 Brest and its department (29) match equipment and flight plan to each order.

Outside military areas the market is real: inspections of civilian port infrastructure and the marine-energy polder, monitoring of the urban cable car and Capucins district works, imagery for Océanopolis and the maritime festivals that gather hundreds of tall ships, and thermography of a post-war rebuilt social housing stock. Brest is one of France's most constrained drone cities: the naval base and arsenal in the heart of town sit under a strict no-fly zone, the Île Longue peninsula (nuclear submarines) south of the roadstead is totally prohibited with reinforced protection, and the Brest-Bretagne CTR extends to the north-east.

€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 Brest.

The airspace context in Brest

A photogrammetric survey in Brest covers the site in parallel flight lines: inside the restricted perimeter (Zone interdite de la base navale et de l'arsenal de Brest), 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 →

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.
