Drone Surveys
UAV capture aligned to verified ground control and delivered with structured quality assurance for projects where coverage, safety and accuracy matter.
A drone survey uses an Unmanned Aerial Vehicle (UAV) to capture photographic and spatial data which can be processed into controlled outputs such as orthomosaics, point clouds and surface models. Using an agreed coordinate system and vertical datum, supported by a defined ground control strategy, UAV datasets can provide reliable measurement at scale for sites that are large, hazardous, or difficult to access.
When aerial capture is completed without rigorous control, defined accuracy, or transparent deliverables, the outputs can be visually impressive but technically unreliable. Profind Surveys delivers UAV capture under defined methodology with verified referencing and quality checks, so the data can be used confidently for planning, measurement and reporting.
Scope Defined Before Mobilisation
Survey requirements are agreed prior to mobilisation, including:
- Purpose of the survey (volumes, surfaces, progress capture, inspection, mapping)
- Survey extent and access constraints
- Required accuracy and tolerance
- Coordinate system and vertical datum
- Ground control strategy (control points, checkpoints, and referencing)
- Flight parameters aligned to the required resolution and accuracy
- Deliverable formats and CAD / model integration requirements
- Constraints relating to operations, site rules and airspace permissions
- LiDAR drone survey (Light Detection and Ranging) to scan the ground and create highly accurate 3D maps and terrain models. It’s commonly used in construction, engineering, mining, forestry, and land surveying.
This prevents ambiguity and ensures outputs match your decision needs.
Control & Measurement
A ground control framework is established or verified before data capture where accuracy is required. Control is referenced to the agreed coordinate system and vertical datum, and flight planning is aligned to resolution requirements and topographic variation across the site.
UAV datasets are processed into measurable outputs using a repeatable workflow. Where UAV capture is used for ongoing comparison, the control framework and methodology are maintained to support like-for-like analysis between survey epochs.
Structured Quality Assurance
All datasets undergo internal QA prior to issue, including:
- Verification of control, datum and coordinate consistency
- Checkpoint residual review to confirm referencing quality
- Surface validation and model integrity checks where applicable
- Review for gaps, distortions and processing artefacts
- Deliverable pack checks (formats, naming, metadata and scope coverage)

Deliverables
Outputs are structured for immediate integration into planning and reporting workflows and may include:
Orthomosaic / rectified imagery (where required)
Point clouds (where specified)
3D surface models / DTMs and contours
Topographical outputs derived from UAV data where appropriate
Photo and video outputs for progress capture and inspection
BIM-compatible / model-ready outputs where specified
Metadata confirming coordinate system, datum, extent and date of capture
All deliverables clearly state survey limits, control reference, and intended use.
Risk Reduction in Practice
A properly specified and quality-assured UAV survey:
- Reduces site access and safety exposure in hazardous or restricted areas
- Speeds up data capture across large sites without sacrificing control
- Supports reliable volume and surface measurement when grounded in verified control
- Enables repeatable progress tracking through consistent epochs and datasets
- Improves decision-making by providing clear, current site context
- Reduces rework by issuing structured outputs ready for CAD/model workflows
Integrated Survey Capability
Where required, drone surveys can be coordinated with:
Quarry and Landfill Surveys
for periodic volume tracking and surface modelling
Topographical survey
to tie aerial capture into a verified control framework
Deformation Monitoring
where movement or slope behaviour requires tracking
Digital Survey Outputs & Model Development
for structured CAD/BIM deliverables
A single verified control framework ensures consistency across all disciplines.

FAQs
What is a drone survey used for?
To capture site imagery quickly and safely, especially across large areas or hard-to-access zones, and support planning and reporting.
Will a drone survey replace a topographical survey?
Not always. Drone outputs can support context and visuals. If you need detailed levels and features for design, you may still need a topo survey. We’ll advise on the scoping call.
Can you combine drone surveys with other survey work?
Yes. Many clients use Profind for drone plus topo, PAS128 utilities, CCTV drainage, GPR and CAD outputs.
How quickly can you mobilise?
It depends on site access, scope, and programme. We confirm timings on the scoping call.
Where do you cover?
Profind Surveys is based in Tamworth and focuses on the Midlands.
Want UAV outputs you can actually measure from?
If you require drone survey data delivered under defined methodology, verified control and structured QA, contact Profind Surveys Ltd to discuss your site, constraints and output requirements.
