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

• Tethered drone: continuous site or event surveillance, principle, regulations, priceThe tethered drone, linked to the ground by a cable, stays airborne continuously with no battery limit. Principle, the regulatory status specific to tethered aircraft, event and security use cases, 2026 prices (excl. VAT).
• Log pile volume by drone: measuring a roundwood stock at a sawmill or in the forest, method and priceMeasuring a log pile's volume by tape takes hours and stays approximate. Drone photogrammetry computes a timber yard's cubic volume in minutes. Method, accuracy, 2026 prices (excl. VAT).
• Spring frost in vineyards and orchards: mapping risk by drone thermal imaging to target candles and wind machines — priceOne radiative frost night can destroy an entire harvest. Drone thermal imaging maps cold-air pockets to target candles, wind machines and sprinklers. Method, night flight, 2026 prices (excl. VAT).
• Mapping windthrow after a storm by drone: quantifying the damage, prioritising salvage logging, priceAfter a storm, windthrown timber loses value fast and draws bark beetles. Drones map the extent and volume of broken trees within hours, to prioritise salvage logging. Method and 2026 prices (excl. VAT).
• Dangerous building at risk of collapse: documenting it by drone, without exposing anyone — method, priceDocumenting a structurally dangerous building by drone as part of a safety-order procedure: roof, façades, interiors seen through openings, without sending anyone inside. For mayors, experts and owners. Method, 2026 prices.
• Wild-boar and game damage to crops: assessing a field by drone, priceQuantifying wild-boar and deer damage to maize, grassland and cereals by drone: actual destroyed area, defensible mapping for the compensation file. Research-backed method, 2026 prices.
• Crop-emergence counting by drone: plant density, missing plants, replanting decision — priceCounting crop emergence by drone on maize, beet or sunflower: actual plant density per hectare, gap zones, replanting decision support. Research-validated methods, flight windows, 2026 prices.
• Façade survey by drone for architects: orthophoto, elevations, accuracy — priceFaçade survey by drone for architects and design teams: rectified façade orthophoto, base for CAD elevation drawings, achievable accuracy, street or courtyard façades. Method and 2026 prices.
• Glass-roof and canopy inspection by drone: stations, shopping centres, atriums — priceInspecting a glass roof, station canopy or shopping-centre atrium by drone: broken or slipped glazing, corroded framing, gutter watertightness — without nets or scaffolding above the public. Method, 2026 prices.
• Steam-network and pipe-insulation thermography by drone: energy losses in plants, priceLocating steam and superheated-water network losses by thermal drone in industrial plants: degraded lagging, bare singular points, failed steam traps, overhead pipe racks. Method, payback, 2026 prices.
• Avalanche-defence structure inspection by drone: snow bridges, racks, nets — pre-season check, priceChecking avalanche-defence structures by drone before winter: deformed snow bridges and racks, net anchors, deflecting works — without helicopter time or approach hikes on steep ground. For municipalities, ski areas and managers. Method, 2026 prices.
• Chimney-stack inspection by drone: roofers, flue specialists, property managers — method, priceInspecting a chimney stack by drone: masonry, crown, flashings, caps and junctions seen up close without climbing the roof. For roofers, flue specialists, property managers and homeowners. What the drone sees, what it does not replace, 2026 prices.
• Municipal solar register by drone: mapping rooftop photovoltaic potential, priceBuilding a municipal solar register by drone: up-to-date digital surface model, real shading masks, per-roof-plane irradiation — to prioritise photovoltaics on public buildings and inform residents. Method, 2026 prices.
• Lifting and carrying loads by drone: construction sites, roofs, hard-to-reach places — rules, priceLifting loads by drone: what cargo drones can really carry in 2026, where they beat mobile cranes or helicopter slinging (roofs, pylons, mountains), the specific-category regulatory framework, and observed prices.
• Drone risk-prevention survey for property insurance: roof, surroundings, priceDocumenting a professional building by drone for property-insurance underwriting or renewal: roof, gutters, surroundings, storage. What the report gives the insurer and the risk manager, its limits, 2026 prices.
• Snow-load roof diagnosis by drone: spotting the collapse risk, priceDiagnosing snow-load risk on an industrial, logistics or commercial roof by drone: thickness mapping, high-risk accumulation zones, decision support for snow removal — without sending anyone onto a snow-covered roof. Method, 2026 prices.
• Aerial fibre-optic network audit by drone: poles, overloading, dangling cables, priceAuditing an aerial fibre-optic network by drone: overloaded poles, unconnected dangling cables, abnormal sag, crossings with power lines. For infrastructure operators, public-initiative networks and delegating authorities. Method, 2026 prices.
• Quarry rehabilitation monitoring by drone: restoration, revegetation, priceMonitoring a quarry's end-of-life rehabilitation by drone: backfill volumes checked against the approved plan, vegetation recovery by sector, early erosion detection on restored areas. Method, 2026 prices.
• Port gantry crane drone inspection: STS, RTG, salt corrosion, VGP, priceInspecting a quay gantry crane (STS), a yard crane (RTG) or a mobile harbour crane by drone: salt corrosion, lattice structure, cabling, travel rails — complementing the mandatory VGP check. Method, 2026 prices.
• Cold-store and refrigerated-warehouse thermography by drone: thermal bridges, priceDetecting thermal bridges and insulation defects in a cold store's envelope by drone: what the camera shows on a cold roof, measurement conditions, value for the cold chain. Method, 2026 prices.
• Cooling-tower drone inspection: structure, corrosion, Legionella context, priceInspecting a cooling tower by drone: structure, corrosion, fill and drift eliminators seen from above, without scaffolding or a long shutdown — within the Legionella-prevention context. Method, 2026 prices.
