Drone Coastal & Erosion Surveys.
Compare quotes from specialist UK drone operators for repeatable, tide-aware coastal surveys — cliff retreat, dune profiling, and flood-defence inspection, delivered as survey-grade orthomosaics and change-detection DTMs.
“For every verified profile, we record the insurance and CAA credentials supplied at the time of review.”

Drone coastal survey specialisms
Baseline and repeat captures for coastal change, defence asset condition and post-storm response.
Erosion monitoring
Repeat-capture DSMs to quantify cliff retreat, beach volume change and shoreline movement.

Cross-section profiles and volumetric change over tidal cycles for coastal engineering.
Request beach profilingSea-defence condition
High-resolution capture of groynes, revetments and sea walls for asset condition reporting.

Coastal engineers, local authorities, and estates managers need timely, repeatable elevation data. Traditional walk-over and vessel surveys simply can't deliver at the cadence erosion demands.
Unsafe Cliff-Face Access
Rope-access assessments on unstable cliffs are slow, weather-dependent, and genuinely dangerous. A drone surveys the same face from standoff in a single session, with no personnel near the edge.
Erosion Data Going Stale
National LIDAR composites are refreshed on multi-year cycles. In high-retreat locations that's far too slow to inform planning, insurance, or managed-realignment decisions. Drone flights give you year-on-year — or monthly — deltas.
Flood Defence Inspection Costs
Inspecting groynes, revetments, and sea walls at low water on foot consumes days of tide windows. A drone captures the entire defence length and crest line in one flight, with centimetre-accurate measurements on the orthomosaic.
Coastal flying is a tide window, not a calendar day.

Connect on LinkedInA useful cliff or dune survey has to be flown at the right tide state, in the right light, and inside the right MCA and CAA clearances. Miss any of those and your dataset is worthless for change-detection against next year's flight.
Every coastal survey on this network is flown by drone operators who plan around LAT/HAT tide data, coordinate with HM Coastguard when appropriate, and lock ground control points so every subsequent flight can be rigorously compared.
The result is a dataset that stands up under planning, insurance, and Environment Agency scrutiny — and still matches to the millimetre when you fly it again next spring.

Deliverables your coastal engineer can actually use.
Our network operators deliver survey-grade outputs ready for coastal engineers, planners, and Environment Agency submissions.
Change-Detection DTMs
Compare this flight's digital terrain model against your baseline to visualise volume lost, dune migration, or crest-line retreat. Colour-coded deltas export straight to GIS for council, insurer, or consultant review.
Tide-Aware Orthomosaics
Every flight is planned against LAT/HAT data so your orthomosaic is comparable to the last one. Geo-referenced, centimetre-accurate, and ready to measure scarp, toe, and defence crest positions against historic imagery.
Annotated Cliff & Dune Reports
Each slump, scarp, blow-out, or undercut is pinned, numbered, and cross-referenced to the source imagery — giving your coastal engineer a defensible, dated record to feed into retreat modelling.
Book your coastal survey in 3 steps.
Submit one brief. We aim to review it within one working day, then introduce relevant independent specialists who can assess the project.
Describe the Site
Tell us the stretch of coast, the feature type (cliff, dune, defence, harbour), and what you need to evidence. Takes under two minutes.
Compare Specialists
We review the brief against relevant verified profiles and current availability. If listed supply is limited, we will say so and source availability manually. Any pilot introduced must confirm equipment, permissions, timing and deliverables for the actual job.
Survey & Report
Your drone pilot files the airspace permissions, flies the coastline at the right tide state, and delivers an orthomosaic, DTM, and annotated change-detection report.
Coastal Survey FAQ
