• Solar Parking Canopies in France: the APER Law, the 2026 Deadline and Where Drones Fit InSince 1 July 2026, French outdoor car parks over 10,000 m² must carry solar canopies under the APER law or face fines. Drone feasibility surveys and post-installation thermography: method and 2026 prices (excl. VAT).
• Drone services in the Alpes-Maritimes (French Riviera): the Nice CTR, Monaco, Cannes and yachting, 2026 pricesTwo nested control zones over fifty kilometres of coast, a permanent helicopter corridor to Monaco, a border with a non-EU state, and temporary prohibited zones during major events.

• Drones in Hauts-de-Seine (92): Where You Can Actually Fly, La Défense and the Office Stock176 km² of continuous urban fabric, 9,400 residents per km²: in Hauts-de-Seine every professional flight is a built-up-area flight, inside the Paris CTR and up against the P23 no-fly zone. B2B missions, real constraints, method and 2026 prices (excl. VAT).
• Drone Work in Gironde (33): Bordeaux Vineyards, Gascony Forest, Arcachon Bay and EstuaryIn Gironde, the hard part is not finding a drone pilot, it is flying in the right week: brush-clearance checks in winter, frost in spring, a fire season that closes the airspace in summer, oyster beds open only at spring tides. Departmental framework, sectors and 2026 prices (excl. VAT).
• 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 the prefect 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.

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.

• 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).
