EU regulations, real prices, mission preparation: concrete answers before commissioning a drone service.

• Drone Sensor and Shutter: Global vs Rolling Shutter, and What It Changes on a SurveyRolling versus global shutter, sensor size, lens: what these three parameters really change on survey accuracy and on video. Published figures, software correction and its limits, specification wording and 2026 prices (excl. VAT).
• Checking a Drone Photogrammetry Deliverable: Processing Report, Check Points, TolerancesA 2 cm RMS printed in a processing report proves nothing. How to read the report, require independent check points and write an enforceable tolerance into your tender. 2026 prices (excl. VAT).
• Spraying by Drone After a Flood: The Emergency Derogation for Vineyards and OrchardsFlooded vines and orchards, no tractor access, downy mildew taking hold: in March 2026 an interministerial order authorised emergency drone spraying in four départements. How this lesser-known derogation works, and its price.
• Flavescence Dorée: Drone Detection, Mandatory Uprooting and the Control CalendarFlavescence dorée: uprooting once 20% of vines are contaminated, three mandatory insecticide treatments against the vector leafhopper. What the research shows on multispectral drone detection, and its 2026 price (excl. VAT).
• Drones Over Cities: What the 23 December 2025 Order Changes for Flying Above Public SpaceSince 1 January 2026, a professional operator can fly in the Open category above public space in French towns and cities — previously banned. Which drones qualify, the declaration required, and the effect on the price of an urban mission.
• Drone Services on the Canal Seine-Nord Europe Site: Construction Monitoring and Archaeological SupportEurope's largest civil engineering site runs 107 km across the Hauts-de-France region: photogrammetric monitoring of earthworks and structures, support for preventive archaeological digs. 2026 method and prices (excl. VAT).
• Balcony, Loggia and Railing Inspection by Drone: What the Flight Sees, What It Cannot Conclude, and the PricesFrance requires no mandatory periodic balcony inspection: liability stays with the owner. A drone gives the front and soffit view of dozens of balconies in half a day, with no lift and no rope access. Method, limits and 2026 prices (excl. VAT).
• Drone Helipad Inspection: Surface, Markings, Lighting and Approach Paths — Method and PricesA hospital or industrial helipad is an aeronautical structure whose condition governs whether an air ambulance can land. What a drone documents — surface, markings, lighting, safety net, approach paths, FOD — and the coordination the flight demands. 2026 method and prices (excl. VAT).
• Unexploded Ordnance Survey Before Earthworks: What a Drone Adds (Magnetometry, LiDAR) and What It Does Not DoBefore excavating a former battlefield, a drone maps inherited micro-relief and can carry a magnetometer. What it documents, its real limits, and where demining takes over. 2026 method and prices (excl. VAT).
• Which Coordinate System for a Drone Survey: RGF93, Lambert-93, Conic Zones and NGF-IGN 1969 HeightsA drone survey can be centimetre-accurate and still miss your drawing: geodetic system, map projection and vertical datum belong in the specification. RGF93, Lambert-93, conic zones, the RAF20 grid, EPSG codes, acceptance checks and 2026 prices (excl. VAT).
• GNSS Signal Loss, Jamming and Spoofing: What It Changes for a Professional Drone MissionSignal masking, multipath, jamming, spoofing: three very different families of GNSS problems, their effect on a drone survey, in-flight warning signs, fallback procedures and the cost of a postponement in 2026 (excl. VAT).
• What a Drone Thermography Report Is Worth: Who Signs It, Under Which Standard, How to Read ItA drone thermography report is only worth something if the operator is certified, the standard applied is named and the measurement conditions are recorded. How to tell a usable deliverable from a gallery of colourful pictures. 2026 prices (excl. VAT).
• Drone Services in Seine-et-Marne (77): Brie Farmland, XXL Warehouses, Quarries and HeritageSeine-et-Marne covers nearly half of the Île-de-France region and lies outside Paris's P23 no-fly zone: it is the département where professional drone work is least constrained. Arable farming, logistics, quarries, heritage. 2026 method and prices (excl. VAT).
• Drone services in the Drôme (France): mistral, orchards and the Rhône corridor, 2026 pricesA department shaped like a strip: an industrial and nuclear corridor to the west, orchards and lavender in the middle, the Vercors and Baronnies mountains to the east — and the mistral dictating the flying calendar. What a professional drone really does in the Drôme, method and 2026 prices (excl. VAT).
• Post-Earthquake Building Assessment: What a Drone Delivers in the First HoursAfter a tremor, the first hours are about triage: which buildings threaten the street, which need a structural engineer on site. A drone documents the upper parts without exposing anyone. French framework, method and 2026 prices (excl. VAT).
• Drone Crowd Size Estimation at Events: What the Law Allows a Private OrganiserA private organiser can estimate crowd size by drone, but outside the framework reserved for French state security forces: anonymity by design, GDPR, no flying over assemblies of people. Method, real uncertainty and 2026 prices (excl. VAT).
• Drone Services in Corsica: Nature Reserves, Wildfires and Coastal Heritage in France's Most Restricted IslandCorsica combines a regional park covering half the island, two of France's most protected nature reserves (including Scandola, where flying is banned) and a wildfire risk shown by the 2026 Restonica fire. Airspace rules, fuel and Posidonia mapping, and 2026 prices (excl. VAT).
• Drone Services in France's Overseas Departments: Same Regulation, Completely Different TerrainGuadeloupe, Martinique, French Guiana, Réunion and Mayotte apply the same drone regulation as mainland France (EU outermost regions), but a radically different terrain: the Guiana Space Centre, an active volcano, cyclone season, VAT at 8.5% or none. Framework, constraints and 2026 prices (excl. VAT).
• Manure Pits and Livestock Effluent Storage: Drone Leak and Methane Detection (ICPE 2101/2102)Mandatory sealing of manure pits, the nitrates directive and storage-cover requirements: what drone thermography and methane measurement bring to a farm under ICPE categories 2101 and 2102. Method and 2026 prices (excl. VAT).
• AI and Professional Drones: What the EU AI Act Changes for Inspection ReportsSince 2 August 2026, most of the EU AI Act applies to the automatic-detection tools used in drone inspection reports. What is already mandatory, what the Digital Omnibus postponed, and how a contractor should organise around it.
• Drone Services in Île-de-France: the P23 No-Fly Zone, Grand Paris Express and La Défense TowersCentral Paris off-limits to drones (the P23 zone), Europe's largest metro construction project, the continent's leading business district and the data centres of Seine-Saint-Denis: drone missions across Île-de-France. 2026 method and prices (excl. VAT).
