Drone surveying & photogrammetry in Gap

Free quote — surveying & photogrammetry in Gap

Surveying sloped ground in Gap on foot takes days; by drone, a few hours: digital terrain models, volume calculations and cross-sections come from a single photogrammetric flight, with centimetre RTK accuracy. From Domaine de Charance to the outlying districts, our pilots know the terrain of Gap and prepare every flight on the local aeronautical chart.

Gap's economy blends administration, Alpine commerce, four-season tourism and hill farming. In the mountains the 120-metre limit is measured from the overflown terrain: slope and valley flights demand real preparation. Drone missions: lake and mountain tourism, real estate, construction monitoring, inspection of EDF structures around Serre-Ponçon (with protocols), mountain agriculture. Prefecture of the Hautes-Alpes and France's highest prefecture (735 m), Gap is the gateway to the southern Alps: twenty minutes away, Lake Serre-Ponçon — western Europe's largest artificial reservoir — with the Saint-Michel chapel on its islet; to the north, the Écrins massif.

Flight rules in Gap

A photogrammetric survey in Gap covers the site in parallel flight lines: inside the restricted perimeter (Cœur du Parc national des Écrins : drones interdits), 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 Gap: 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 Gap into your schedule: several weeks depending on the case.

What accuracy can a drone survey achieve in Gap?

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 Provence-Alpes-Côte d'Azur.

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.
