Professional Drone LiDAR Surveys Across the UK

UAV Surveys UK provides professional drone LiDAR surveys across the UK, capturing high-density, georeferenced three-dimensional data for topographical surveying, terrain modelling, infrastructure, construction, vegetation and complex sites.

​

Our UAV LiDAR systems combine laser scanning with accurate GNSS positioning and inertial measurement technology to capture detailed point-cloud data from the air. The resulting data can be processed into survey-ready point clouds, digital terrain models, contours, 3D models and other geospatial deliverables.

​

Whether you require a survey of a large development site, earthworks, infrastructure corridor, woodland, difficult terrain or an area where conventional surveying would be difficult or time-consuming, airborne LiDAR can provide an efficient method of collecting detailed three-dimensional information.

We operate throughout the UK.

What is Drone LiDAR?

LiDAR, or Light Detection and Ranging, uses laser pulses to measure distances between the sensor and the ground or other surfaces.

​

A drone-mounted LiDAR scanner can rapidly collect thousands of measurements per second while the aircraft follows a planned survey flight. These measurements are combined with precise positioning and orientation data to create a three-dimensional point cloud representing the surveyed environment.

Unlike conventional aerial photography, LiDAR does not rely on visible imagery to measure the ground. This makes it particularly useful for terrain and vegetation-rich environments where obtaining reliable ground information from photogrammetry alone can be difficult.

Drone LiDAR Survey Applications

​

Our LiDAR surveying services can be used for a wide range of commercial, engineering and environmental applications, including:

​

Topographical Surveys

Capture detailed terrain information across large or difficult-to-access sites for engineering, development and design projects.

LiDAR data can be processed into:

• Digital Terrain Models (DTM)

• Digital Surface Models (DSM)

• Contour models

• Classified point clouds

• Elevation datasets

• 3D terrain models

• CAD and GIS-compatible data

Construction and Earthworks

LiDAR can provide an efficient way of surveying construction sites, earthworks and large development areas.

Applications include:

• Existing-ground surveys

• Construction progress monitoring

• Cut-and-fill analysis

• Earthworks measurement

• Site modelling

• Quarry and aggregate surveys

• Stockpile measurement

• As-built surveys

Repeated surveys can also provide a consistent record of changes across a site during construction.

​

Vegetation and Woodland

​

One of the major advantages of LiDAR is its ability to collect information through gaps in vegetation.

Where suitable conditions exist, laser pulses can reach the ground beneath vegetation and provide information that may be difficult to obtain using conventional aerial photogrammetry.

This makes LiDAR particularly useful for:

• Woodland surveys

• Vegetation assessment

• Overgrown sites

• Land management

• Drainage and terrain analysis

• Infrastructure corridors

​

The effectiveness of LiDAR in vegetation depends on factors including vegetation density, species, season, flight parameters and sensor characteristics. We therefore select the appropriate survey methodology for each project rather than assuming LiDAR is the best solution in every situation.

​

Infrastructure Surveys

Drone LiDAR can be used to collect detailed three-dimensional information around infrastructure while reducing the requirement for personnel to physically access difficult areas.

Potential applications include:

• Roads

• Rail infrastructure

• Bridges

• Utilities

• Industrial sites

• Pipelines

• Embankments

• Quarries

• Renewable energy sites

​

LiDAR data can be combined with imagery and other survey information to provide a comprehensive representation of the surveyed asset or environment.

​

LiDAR and Photogrammetry

​

LiDAR and photogrammetry each have advantages, and the appropriate technology depends on the survey requirements.

​

Photogrammetry derives three-dimensional information from overlapping photographs. It can produce highly detailed imagery, orthomosaics,
