What Is a Drone Coastal Survey?

A drone coastal survey uses UAV-mounted cameras and sensors to capture high-resolution aerial data of coastlines, cliffs, beaches, and sea defences. This technology allows us to create detailed maps, 3D models, and change detection analyses that reveal erosion patterns, structural conditions, and environmental changes along the UK's shores.

At Drone Survey Services, we deploy specialist coastal survey equipment capable of capturing centimetre-accurate data across challenging coastal environments. Our surveys provide coastal authorities, engineers, and environmental consultants with the precise information they need to monitor erosion, plan interventions, and protect valuable coastal assets.

How Much Does a Drone Coastal Survey Cost?

Pricing depends on the length of coastline and complexity of your project. Here's a guide to help you budget:

*Guide prices include standard deliverables. Final quote based on site complexity, access, and specific requirements.

What affects your quote?

• Coastline length & terrain
• Required deliverables
• Turnaround time
• Access & permissions

Our drone-based approach typically saves 50–70% compared to traditional coastal survey methods. Contact us with your project details and we'll provide a tailored quote within 24 hours.

What Is the Difference Between Drone Coastal Survey and Traditional Methods?

Traditional coastal surveys typically rely on ground-based GPS measurements, theodolite stations, or manned aircraft. While effective, these methods are often time-consuming, expensive, and limited in the data they can capture—particularly on hazardous cliff faces or dynamic beach environments.

Drone coastal surveys transform this approach entirely. Our UAVs can safely access cliff tops, vertical faces, and remote sections of coastline that would be dangerous or impossible for ground teams. We capture thousands of high-resolution images that produce detailed orthomosaics and 3D models, enabling precise volumetric analysis of erosion and accretion.

What Accuracy Can a Drone Coastal Survey Achieve?

Our drone coastal surveys routinely achieve vertical accuracy of ±2-5cm and horizontal accuracy of ±3-5cm when using ground control points. This precision is essential for detecting subtle erosion patterns, measuring cliff recession rates, and quantifying sediment movement along beaches.

We deploy RTK/PPK-enabled drones combined with strategically placed ground control points to ensure every measurement meets survey-grade standards. For repeat monitoring surveys, we maintain consistent control networks to ensure accurate change detection between epochs. The result is data you can trust for engineering decisions, planning applications, and scientific research.

What Are the Applications of Drone Coastal Survey?

Drone coastal surveys serve a wide range of industries and applications across the UK. Here are the key areas where our clients see the greatest value:

Can Drones Monitor Coastal Erosion?

Absolutely—this is one of the most powerful applications of drone coastal survey technology. By conducting repeat surveys at regular intervals, we can precisely measure how coastlines are changing over time. Our change detection analysis reveals erosion rates, identifies vulnerable sections, and quantifies sediment loss or gain with centimetre accuracy.

We overlay survey data from different epochs to create visual change maps that clearly show where erosion is occurring and at what rate. This information is invaluable for coastal authorities planning protective measures, property owners understanding cliff recession risks, and engineers designing sea defences.

Our monitoring programmes can be scheduled annually, bi-annually, or after significant storm events to track both gradual erosion and sudden cliff failures. Each survey builds a comprehensive time-series dataset that reveals trends and helps predict future coastal change.

What Deliverables Do You Get From a Drone Coastal Survey?

We tailor deliverables to your project requirements, but our standard drone coastal survey outputs include:

• High-Resolution Coastal Orthomosaic

  Georeferenced aerial imagery of your coastline at 2-3cm/pixel resolution. Perfect for visual documentation and GIS analysis.

• Erosion Analysis & Change Detection

  Quantified volumetric changes, recession rates, and visual comparison maps when comparing to previous surveys.

• Cliff Profiles & Cross-Sections

  Detailed elevation profiles at specified intervals along cliff faces, showing geometry and highlighting instability risks.

• CAD Files & 3D Models

  DWG/DXF files for engineering use, plus detailed 3D mesh models for visualisation and analysis.

• Digital Surface Model (DSM)

  Elevation model of the coastal surface for contour generation, slope analysis, and flood risk assessment.

How Long Does a Drone Coastal Survey Take?

On-site data capture is remarkably fast compared to traditional methods. We can survey 5-10km of coastline per day depending on conditions and site complexity. A typical 1-2km cliff section takes just 2-3 hours of flight time, including setup and ground control establishment.

Processing and delivery depends on project complexity and your required outputs. Standard deliverables are typically ready within 5-7 working days. For urgent projects, we offer expedited processing with 48-72 hour turnaround available at additional cost. We'll confirm realistic timescales when we quote your project.

How Do I Choose a Drone Coastal Survey Provider?

Not all drone survey providers have experience with the unique challenges of coastal environments. When evaluating providers, we recommend checking these key factors:

• CAA authorisation – Ensure they hold valid GVC or legacy PfCO permissions for commercial operations
• Coastal survey experience – Coastal environments require understanding of tides, wind conditions, and salt exposure
• Professional insurance – Public liability and professional indemnity cover appropriate to your project
• Change detection capability – Ask about their software and workflows for erosion monitoring
• Relevant case studies – Request examples of similar coastal projects they've completed

At Drone Survey Services, we tick every box. We're CAA approved, fully insured, and have delivered drone coastal survey projects for councils, engineering consultancies, and environmental organisations throughout the UK.

Is Drone Coastal Survey Cheaper Than Traditional Methods?

In most scenarios, significantly so. Traditional coastal surveys often require expensive boat-based access, rope access teams for cliff faces, or manned aircraft flights. These methods are not only costly but also time-consuming and weather-dependent.

Our drone coastal surveys capture equivalent or superior data in a fraction of the time and cost. A cliff section that might take a rope access team several days can be surveyed by drone in hours. The cost savings typically range from 50-70% compared to traditional methods, while delivering faster turnaround, higher resolution data, and safer operations. For long-term monitoring programmes, the economics become even more favourable with repeat surveys.
