Free quote — surveying & photogrammetry in La Roche-sur-Yon

Around La Roche-sur-Yon, land consolidation, development zones and infrastructure call for up-to-date surveys: the drone covers dozens of hectares per flight and delivers DTMs, contour lines and volumes with fully traceable accuracy. From the town centre to the business parks, the pilots covering La Roche-sur-Yon and its department (85) match equipment and flight plan to each order.

Prefecture of the Vendée, La Roche-sur-Yon is an urban-planning rarity: a town created from scratch by Napoleon in 1804, with a pentagonal grid plan perfectly legible in aerial photography. Napoléon square, redesigned with its mechanical animals, Saint-Louis church and the Vendée stud farm are its pivots. La Roche-sur-Yon - Les Ajoncs aerodrome (LFRI), to the north-east, is the main local aeronautical constraint. The department has one of France's lowest unemployment rates, driven by a dense fabric of industrial SMEs (food processing, boat building, construction).

Frequently asked questions

Surveying & photogrammetry in La Roche-sur-Yon: what budget should you plan?

Allow €800–3,000 per day — the 2026 French market range, including regulatory preparation, flight and delivery. In La Roche-sur-Yon, coordination with the local airspace is included in the quote and arranged within a few days.

What accuracy can a drone survey achieve in La Roche-sur-Yon?

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.

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.
