CAA-Approved Linear Asset Mapping

Drone Corridor Mapping.

Compare quotes from specialist UK drone operators for long-linear infrastructure — pipelines, overhead powerlines, railways, and highways — captured in a single automated flight. No more cobbling together multi-day walk-overs or chartering helicopters.

“Every drone pilot on this network is personally vetted by me — insurance, qualifications, flight history.”

Walking a linear asset is a nightmare. And a helicopter is overkill.

Utility managers, network engineers, and asset owners burn weeks on foot patrols or thousands on rotary wing flights. Drone corridor missions slice through miles of infrastructure in a single automated sortie.

Helicopter Patrols Are Expensive

A rotary wing line patrol runs £2k–£5k an hour and still gives you blurry oblique stills. A drone corridor mission covers the same route with survey-grade stills and thermal at a fraction of the cost — and you own the data.

Vegetation & Encroachment Risk

Unmanaged vegetation near powerlines, unauthorised fencing across easements, and illegal dumping along pipelines all become liabilities fast. A dated, georeferenced strip gives you objective evidence for landowner discussions and enforcement.

Foot Patrol Access Is Unsafe

Walking live rail, A-road verges, or remote pipeline routes exposes crews to traffic, trespass, and lone-working hazards. A drone keeps humans out of the danger corridor while capturing richer data than a clipboard ever could.

Corridor jobs cross landowners, highways, rail property, and restricted airspace. A standard A2 CofC drone pilot simply cannot legally fly most of these missions — and yet asset owners still get cold-called by drone operators offering to try.

Every corridor drone pilot on this network holds a full CAA Operational Authorisation with specific permissions tuned to linear flying, coordinates with Network Rail ORR requirements, National Grid OSAs, or DNO safety regimes where needed, and manages airspace clearances up-front.

That means your brief lands with someone who can actually deliver it legally — not just enthusiastically.

Linear-Asset Qualified

Bespoke OA & £5M Public Liability

Outputs built for GIS, asset management, and enforcement teams.

Our network operators deliver corridor datasets ready for ArcGIS, QGIS, and your existing asset register.

Georeferenced Ortho Strips

A continuous seamless image strip along the entire corridor at 3–5 cm per pixel. Delivered as tiled GeoTIFFs ready to drop into ArcGIS Pro or QGIS with all your existing asset layers.

Route Elevation Profiles

A cross-section along the full route showing ground height, asset height, and clearance. Invaluable for sag-and-swing analysis on powerlines, gradient checks on pipelines, or drainage modelling on highways.

Encroachment Reports

A pinned, numbered, and photographed log of every encroachment, vegetation breach, or third-party interference along the corridor. Ready for landowner letters, enforcement action, or works programming.

Book your corridor mapping in 3 steps.

We connect you with the specific linear-asset specialists you need, instantly.

Describe the Route

Share the asset type, total length, start and end grid references, and the output format you need. A KML or shapefile of the centreline is ideal but we can work from a description.

Compare Specialists

We route your brief to corridor-rated drone pilots in your region. You receive competitive quotes with platform specs, airspace clearance plans, and turnaround times.

Fly & Deliver

Your drone pilot files all permissions, flies the automated mission, and delivers ortho strips, elevation profiles, and encroachment logs through a secure cloud workspace.

"We used to charter a helicopter for quarterly line patrols at eye-watering cost. Switched to a drone corridor mission through this platform and got a 14-km strip with full vegetation encroachment log for less than a single rotary hour."

Malcolm Fraser

Network Engineer, Inverness

"The encroachment report picked up three fences built across our easement that had been missed by two previous walk-overs. It paid for the flight ten times over in the first month of enforcement action."

Claire Whitmore

Easements Officer, Coventry

"We specified a route elevation profile for a 9-km gravity pipeline feasibility. The drone deliverable dropped straight into our hydraulic model and saved our civils team a fortnight of level runs in the field."

Corridor Mapping FAQ

Technical questions on route length, airspace, and deliverables.

How long a corridor can be flown in a single day?

A typical multi-rotor corridor mission covers 5–10 km per flying day at 3 cm per pixel. Fixed-wing and VTOL platforms can stretch that to 40 km+ in a shift where airspace allows. For routes longer than a BVLOS segment, drone operators stage the mission across multiple launch points.

Can you fly beyond visual line of sight (BVLOS)?

A subset of drone operators on this network hold BVLOS operational authorisations and can fly long-linear routes under a single segmented atypical air environment or with on-board detect-and-avoid. Tell us in the brief if BVLOS is essential — we will route only to drone pilots who can legally execute.

Will the data work with my existing GIS and asset system?

Yes. Outputs are delivered in open formats — GeoTIFF for rasters, Shapefile or GeoPackage for vectors, and LAS/LAZ for point clouds — geo-referenced to OSGB36 or WGS84 as you prefer. Everything drops cleanly into ArcGIS Pro, QGIS, Bentley OpenCities, or Cadcorp SIS.

Can you add thermal data for powerline inspections?

Yes. Many corridor drone operators fly a dual payload (visual plus radiometric thermal) so you get both a georeferenced ortho strip and a thermal hot-spot report in the same mission. Especially useful for identifying hot joints on distribution lines or leaks along buried district heating mains.
