DTA delivers a complete inspection capability for industrial sites: photographic and video inspection, 3D modelling and land topographical surveying, all from a single visit.

Volumetric surveys for construction earthworks, quarries, mining and landfill sites: quick, accurate, safe and cost-effective, with results delivered digitally.

Blade condition and pitch angle can be inspected quickly, safely and cost-effectively by drone, without stopping the turbine or sending a technician up on rope access.

Aerial and ground-based photography and video combine to give event organisers striking promotional material that captures scale and atmosphere in a single shot.

High-impact aerial imagery like this gives websites and social media campaigns a striking, unmistakably drone-shot visual.

Aerial drone photography and video built for construction promotional PR, showing a project's scale and progress from an angle ground-based cameras can't reach.

DTA's elevated MAST solutions add an extra dimension to aerial photography and video for the many situations where drones are difficult or illegal to fly.

Drones give heritage sites a safe way to be inspected up close, especially useful where the fabric itself, as at this Chepstow site, is inherently unstable.

DTA drones and MASTs together deliver a complete structural inspection capability for heritage sites: fast, safe, thorough and cost-effective, as demonstrated at this St Davids survey.

A complete inspection capability for wind farms: photographic and video inspection, 3D modelling and land topographical surveying, delivered from the same drone platform.

Fast, accurate, safe and cost-effective topographical surveying, suited to construction sites, mines, quarries and landfill alike.

DTA runs 4x4 vehicles with full off-road capability, so quarry, mining, landfill and construction sites with difficult vehicular access are never a barrier to a survey.

DTA's in-house engineering knowledge lets us innovate with new processes and software to solve inspection challenges that off-the-shelf approaches can't.

Already paying for a fixed time-lapse camera on site? DTA can provide monthly site-monitoring flights that deliver more complete coverage and an end-of-project pseudo time-lapse video, for roughly the same cost.

DTA's 4x4-mounted elevated MAST photography and video solution delivers highly effective roof inspections in areas where drones are unsafe or illegal to operate, as at this site in Reading.

MAST roof inspections are the ideal solution for inner-city locations where drone flight simply isn't permitted.

Drones provide a safe, cost-effective way to carry out structural and condition inspections at height, without scaffolding or rope access.

Drone roof inspections in Newport: fast, safe, thorough and excellent value compared with traditional access methods.

DTA's cloud-based survey data delivery and analysis tools let engineers access and analyse results anytime, anywhere, from a simple PC, laptop or tablet via the web.

Drones aren't a one-tool-fits-all solution, no engineering tool ever is. DTA's 4x4 MAST solutions provide an excellent complementary capability alongside our drones for industrial inspection work.

Safety inspections of construction and industrial high-rise equipment are made simple, quick, safe and cost-effective using drones.

A complete inspection capability for industrial sites: photographic and video inspection, 3D modelling and land topographical surveying, delivered from a single drone platform.

DTA works with many of the UK's largest engineering consultants, civil engineering, construction, quarrying and mining, and utilities companies: the working relationship behind this Geomatics World feature.

Drones are ideal for construction site topographical surveys: this one covers a site near Bristol.

Quarries, mines and landfill sites have rapidly become core business for DTA, with nadir imagery like this forming the basis of accurate site models.

Drone inspections are ideal for surveying old industrial structures ahead of demolition, giving a full record before the site changes for good.

Drones are ideal for chimney and smoke stack inspections, both external and, with a protected ball drone, internal too.

The Normalized Difference Vegetation Index (NDVI) measures plant greenness and photosynthetic activity, and is one of the most widely used vegetation indices in precision agriculture.
