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

• Vineyard and crop water stress by drone: thermal, multispectral, irrigation, priceHow thermal and multispectral drones map water stress in vineyards and field crops to steer irrigation plot by plot: CWSI method, typical campaigns, observed 2026 pricing.
• France's tertiary decree: drone thermography to target energy retrofitsHow drone thermography of the building envelope (roofs, facades) helps organisations covered by France's tertiary-sector energy decree prioritise the works that will cut reported consumption. Method and 2026 prices.
• Digital twin of a building or site by drone: photogrammetry, scan-to-BIM, pricePoint cloud, 3D mesh, orthophotos, BIM model: how a drone builds the digital twin of a building, an industrial site or a property portfolio, what it enables, and observed 2026 pricing.
• Fire-damaged building survey by drone: risk-free assessment, insurance, priceAfter a fire the structure is unstable and access forbidden: drones document collapsed roofs, frames and residual hot spots for the loss adjuster and insurer without endangering anyone. Method and 2026 prices.
• Port structure inspection by drone: quays, breakwaters, riprap, priceQuays, rubble-mound breakwaters, armour layers, roundheads: how drones inspect port structures and track block movements with repeated photogrammetry. Method, port regulations, 2026 prices.
• Urban heat islands: drone thermal mapping for local authoritiesMapping urban heat islands with thermal drones: surface temperature block by block, prioritising greening and de-paving, before/after evaluation. Method and 2026 prices.
• Solar car park canopies: drone survey, construction monitoring and thermographyFrance's APER law requires car parks over 1,500 m² to install solar canopies. Drones serve every stage: topographic survey, construction monitoring, commissioning and O&M thermography. 2026 prices.
• Agricultural drone spraying and spreading: what France allows, priceDrone spraying of crop protection products in France: the default ban, steep-slope experiments, and what is already permitted — trichogramma release, cover-crop seeding. The 2026 framework and prices.
• Wetland mapping by drone: pre-delineation, water law files, priceHow drones help pre-locate and map wetlands: micro-topography, hygrophilous vegetation, support for French water law files and inventories — without replacing field soil science and botany. 2026 prices.
• Can a foreign drone operator work in France? EU recognition and formalitiesEU operator registration, remote pilot certificates, flight categories: what travels from one country to another for a drone provider, and what stays national (flight zones, declarations). The 2026 framework.
• Transport pipeline right-of-way monitoring by drone: method, regulations, priceGas pipelines, oil pipelines, chemical product lines: drones are gradually replacing helicopters for right-of-way patrol. French multi-fluid order, surveillance and maintenance programme, 2026 prices.
• Environmental impact studies (wind, solar): the drone's role in wildlife and flora surveys, priceRenewable energy developer or ecological consultancy: how drones complement the naturalist survey of an environmental impact study (habitats, birds, bats) over the full biological cycle the law requires. Method, 2026 framework, prices.
• Offshore wind turbine drone inspection: method, maritime regulations, priceHow drones inspect the blades and saltwater corrosion of an offshore wind turbine, what maritime overflight changes for the regulations, and 2026 prices.
• Cable car and ski lift drone inspection: pylons, cables, stations, priceCable cars, gondolas, chairlifts: how drones complement STRMTG inspections by documenting pylons, anchor points and stations, without replacing cable testing. Method and 2026 prices.
• District heating network leak detection by thermal drone: method, priceHow a thermal drone spots leaks and heat losses on a buried district heating network, the right flight conditions, and observed 2026 pricing for local authorities and operators.
• Brownfield mapping by drone: redevelopment, land-use targets, priceOrthophoto, 3D model and visual survey of an industrial brownfield by drone: what mapping brings to redevelopment projects under French land-use targets, and observed 2026 pricing.
• Ecological compensation monitoring by drone: mitigation hierarchy, method, priceHow drones document environmental compensation measures (revegetation, wetlands, hedgerows) required by the French mitigation hierarchy, and observed 2026 pricing.
• Municipal orthophoto by drone: uses, accuracy, price for a local authorityWhy a municipality commissions a drone orthophoto (planning, network management, roads, communication), the accuracy achievable versus national imagery, and observed 2026 pricing.
• RTK or PPK drone: what centimetre accuracy is for and when to require itRTK, PPK, ground control points: what these options really change about drone survey accuracy, which missions justify requiring them in a specification, and their impact on 2026 pricing.
• Tank, boiler and confined space inspection by drone: method, safety, priceHow a caged indoor drone inspects tanks, boilers, silos and ducts without sending anyone into a confined space, what French labour law says, and observed 2026 pricing.
• Agrivoltaics: drone monitoring of crops and panels, method and priceWhy agrivoltaic installations must prove farm production is maintained (French 2023 law and 2024 decree), how a drone monitors crops and panels in one flight, and 2026 pricing.
