Aerial Surveying

See the whole site.
Understand every detail.

Coordinated aerial survey information for planning, engineering and construction — captured efficiently and underpinned by professional survey control.

A clearer view of complex sites

Surveying from a different perspective.

UAV surveying provides an efficient way to capture extensive and difficult-to-access areas while maintaining the structure, control and quality expected from an engineering survey.

High-resolution aerial imagery can be processed into coordinated survey datasets for planning, design, progress review and construction decision-making.

The aerial capture is considered alongside the wider project requirement, allowing it to complement topographic surveying, terrain modelling, volumetrics and terrestrial observations where appropriate.

Professional survey methodology

Accuracy starts before take-off.

Every aerial survey is supported by a robust survey control network established using a combination of GNSS and total station observations.

This provides a dependable spatial framework for the aerial capture, helping ensure the resulting datasets are correctly referenced within the agreed project coordinate system.

Control, flight planning, capture conditions, processing and quality assurance are considered together so the final information is suitable for its intended engineering, planning or construction use.

A controlled workflow

From site control to coordinated deliverables.

Each stage is planned around the required outputs, site conditions and level of detail.

01

Survey control

GNSS and total station observations establish the project framework.

02

Mission planning

Coverage, ground resolution, access and constraints are reviewed before capture.

03

Aerial capture

Overlapping imagery is collected systematically across the required area.

04

Processing

Imagery and survey observations are combined into a coordinated dataset.

05

Quality assurance

Control, coverage and outputs are reviewed against the project requirements.

06

Delivery

Information is issued in practical formats for the wider project team.

What aerial capture can produce

Useful outputs, not just impressive imagery.

01

Orthomosaic imagery

High-resolution, georeferenced aerial imagery for design review, reporting and site records.

02

Digital terrain models

Coordinated surface information supporting earthworks, drainage and site design.

03

Point clouds

Dense three-dimensional survey data for analysis, coordination and further modelling.

04

Mesh models

Textured three-dimensional representations for inspection, context and visual communication.

05

Contours and levels

Terrain information prepared for planning, engineering and construction workflows.

06

Progress imagery

Repeatable aerial records that communicate construction progress across the wider site.

Where aerial surveying adds value

Efficient capture across complex and extensive sites.

The suitability of UAV surveying depends on the site, airspace, required accuracy, surface conditions and intended deliverables. We review these factors before recommending the method.

Why aerial surveying

A practical method when scale, access and visibility matter.

01

Large-area coverage

Capture extensive sites efficiently and consistently.

02

Safer access

Reduce unnecessary ground access to difficult or hazardous areas.

03

Site-wide context

Understand individual features within the wider project environment.

04

Coordinated outputs

Integrate aerial information with wider survey and design datasets.

05

Clear communication

Present complex sites in a format that is easy for project teams to review.

06

Repeatable records

Build a visual and measurable record as projects progress.

Frequently asked questions

Aerial survey questions, answered.

Send us the site location, boundary and required outputs, and we can advise whether aerial surveying is suitable.

How accurate are aerial surveys?+

Accuracy depends on the required ground resolution, survey control, flight geometry, terrain, surface visibility and processing method. The intended use and accuracy requirement should be agreed before capture.

Do you establish survey control?+

Yes. A robust survey control network can be established using a combination of GNSS and total station observations to coordinate the aerial dataset within the required project system.

Can aerial surveys be combined with topographic surveys?+

Yes. Aerial capture can complement terrestrial topographic surveying where additional detail, obscured features or higher-confidence ground observations are required.

What deliverables can be provided?+

Depending on the project, deliverables may include georeferenced imagery, point clouds, terrain models, contours, CAD information, mesh models and progress imagery.

Is UAV surveying suitable for every site?+

No. Airspace, weather, access, vegetation, surface visibility, privacy, site restrictions and the required output all influence whether aerial capture is the right method.

Can you provide repeat progress captures?+

Yes. Repeat aerial capture can provide a consistent visual record across agreed construction stages, subject to site and flight conditions.
