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

• Hydropower penstock inspection by drone: corrosion, supports, geometry, priceInspecting a hydropower penstock by drone: external corrosion, supports and anchor blocks, deformation, 3D survey. Method and 2026 prices (excl. VAT).
• Grassland biomass and grass-height estimation by drone: pastures, forage, catch crops, priceEstimating grassland biomass and grass height by drone: grazing and cutting management, catch crops. Method (height model, indices) and 2026 prices (excl. VAT).
• Trichogramma release by drone: corn-borer biocontrol, method and priceDeploying Trichogramma by drone against the European corn borer: biocontrol principle, timing, work rate, regulation. Method and 2026 prices (excl. VAT).
• Invasive plant mapping by drone: knotweed, water primrose, method and priceMapping invasive alien plants by drone (Japanese knotweed, water primrose, ragweed): detection, patch monitoring, management. Method and 2026 prices (excl. VAT).
• Spruce bark-beetle detection by drone multispectral: spotting attacks before browning, priceDetecting spruce trees attacked by bark beetle (Ips typographus) with a multispectral drone before browning: indices, green-attack limits, sanitary felling. Method and 2026 prices (excl. VAT).
• Nocturnal wildlife counting by thermal drone: deer, wild boar, hunting plans, priceCounting large wildlife by thermal drone at night: deer, wild boar, support for hunting plans and collision prevention. Method, limits and 2026 prices (excl. VAT).
• Road signage and equipment inventory by drone: signs, barriers, markings, priceInventorying road signage and equipment by drone: signs, barriers, markings, furniture. Geolocation, asset database. Method and 2026 prices (excl. VAT).
• Rampart and fortification inspection by drone: masonry, defects, 3D survey, priceInspecting and surveying a rampart, city wall or fort by drone: masonry, joints, vegetation, defects. Photogrammetry, 3D model, monitoring. Method and 2026 prices (excl. VAT).
• Leak detection on irrigation canals and networks by thermal drone: method and priceDetecting leaks and seepage on an irrigation canal or network by thermal drone: water losses, seepage points, repair prioritisation. Method and 2026 prices (excl. VAT).
• Tree health and fall-risk assessment by drone: method, complement to VTA, priceDetecting tree decline and fall risk by drone: crown seen from above, vegetation indices, inaccessible canopy. A complement to ground-based VTA assessment, method and 2026 prices (excl. VAT).
• 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.
