Question 1

What are the advantages of drone surveying over traditional survey methods?

Accepted Answer

Drone surveying can capture large areas quickly while producing high-resolution, accurately georeferenced imagery and 3D data. This provides far more information than a conventional survey alone. The data can be used for mapping, encroachment inspection, development monitoring, stockpiles and progress reporting.

Question 2

How accurate is drone LiDAR and photogrammetry?

Accepted Answer

Accuracy depends on the technology, site conditions, survey control and required deliverables. DSI uses GNSS positioning, survey control and established workflows to produce accurately georeferenced datasets. The appropriate technology is selected according to the accuracy required for each project.

Question 3

What is the difference between a traditional survey and reality capture?

Accepted Answer

A traditional survey typically collects specific points and measurements required for a particular purpose. Reality capture collects millions of spatial measurements and images to create a detailed digital representation of an environment. This data can then be measured, modelled, inspected and revisited for multiple applications.

Question 4

Can I view the captured data without specialist software?

Accepted Answer

Yes. DSI can provide interactive, web-based ways of viewing captured data, depending on the project. This allows clients and stakeholders to explore, measure and share 3D data without specialist point-cloud software.

Question 5

Can drone surveys be used for stockpile measurements?

Accepted Answer

Yes. UAV LiDAR and photogrammetry can rapidly capture stockpiles and generate detailed 3D surfaces. These surfaces can be used to calculate volumes, contours and other measurements. This can also reduce the need for personnel to physically access stockpiles.

Question 6

Can DSI inspect structures using drones?

Accepted Answer

Yes. Drones can capture high-resolution visual and thermal imagery of structures and assets. This can reduce the need for scaffolding, rope access and personnel working at height. Applications include towers, tanks, bridges, pylons, chimneys, dams and roofs.

Question 7

Can you capture data while the site is still operating?

Accepted Answer

In many cases, yes. UAV and remote reality-capture methods can reduce the amount of time personnel need to spend within operational areas. This can minimise disruption to ongoing operations while still providing detailed spatial data.

Question 8

What deliverables can DSI provide?

Accepted Answer

Depending on the project, DSI can provide point clouds, 3D models, orthomosaics, topographic data, contours, stockpile volumes, 360° imagery and inspection imagery. We can also provide thermal data, as-built documentation, interactive 3D models and virtual tours.

Question 9

How do I know which technology is right for my project?

Accepted Answer

You don't need to — that's our job. DSI assesses the project requirements and selects the most appropriate combination of surveying, UAV, LiDAR, photogrammetry, scanning and inspection technologies. This ensures you receive the right data for the job without unnecessary technology or cost.

Question 10

Why should I use DSI instead of a traditional survey company?

Accepted Answer

Because we don't just capture points — we capture the environment. DSI combines professional surveying expertise with UAV, LiDAR, photogrammetry, terrestrial scanning and reality-capture technologies. The result is data that can be measured, modelled, inspected, monitored and shared.
