What Are the Benefits of Using a Drone for Surveying?

Time is money in any project. Traditional land or property surveys can take days, sometimes even weeks, depending on the size and complexity of the site. By contrast, drones can cover large areas in a fraction of the time.

Aerial drones capture high-resolution imagery, video, and LiDAR data across entire sites in just a few hours. This means stakeholders can make decisions sooner, identify potential issues early, and keep projects moving forward without unnecessary delays.

For industries like construction, where progress monitoring is essential, faster data capture is a huge advantage. A drone construction survey can map a site, measure stockpiles, or track progress in near real-time – something traditional methods simply can’t match.

Another clear benefit of drone surveying is cost savings. Traditional methods often require:

• Specialist access equipment (scaffolding, cherry pickers, MEWPs). 
• Multiple staff on-site. 
• Extended downtime or site closures. 

Drone surveys eliminate many of these expenses. One or two operators can complete the work quickly, without the need for costly equipment or prolonged disruption.

For example, a drone roof survey removes the need for scaffolding or working at height. A drone can capture detailed imagery of roof conditions safely from above – at a fraction of the price.

When scaled across multiple sites or larger projects, the savings become substantial.

Safety is a top priority for every business. Surveying traditionally required people to work at height, in confined spaces, or around hazardous environments. Each of these scenarios introduces risk.

Drones remove that risk. Instead of sending a surveyor into a dangerous culvert, onto a fragile roof, or up a tall structure, a drone can collect the same (or better) data while operators remain safely on the ground.

At DJM Aerial Solutions, our confined space drone surveys use the cutting-edge Elios 3 platform, which can navigate silos, tanks, ducts, and underground culverts with 360° lighting and LiDAR mapping. This allows us to carry out internal inspections without endangering human lives.

Some people assume drones can’t match the accuracy of traditional surveying equipment – but the reality is the opposite. Modern drone platforms are equipped with:

• RTK (Real-Time Kinematic) GPS for centimetre-level accuracy. 
• LiDAR sensors for detailed 3D mapping. 
• High-resolution cameras capable of producing crystal-clear imagery. 

Whether it’s a drone property survey, a land boundary measurement, or volumetric calculations for construction, drones can deliver highly accurate, detailed outputs. These datasets are compatible with BIM (Building Information Modelling) software, CAD drawings, and digital twin applications.

One of the most powerful features of drone surveying is the ability to share data instantly. Once a drone survey is complete, information can be uploaded to cloud-based platforms and shared with project managers, contractors, or stakeholders in real time.

Outputs can include:

• 3D point clouds 
• Orthomosaic maps 
• Digital twins 
• Thermal images 
• High-resolution inspection videos 

This means everyone involved in the project can see the same accurate, up-to-date information – leading to better collaboration and faster decision-making.

Traditional surveys often require parts of a site to be closed or restricted while measurements are taken. For active construction projects, factories, or transport networks, this disruption can be costly.

Drone surveys solve this problem. By operating from above or within controlled airspace, they can capture the required data without halting operations.

For example:

• A drone roof inspection can be completed while the building remains in use. 
• A drone culvert survey can be carried out without shutting down roads or infrastructure. 
• A construction drone survey can be performed without interfering with machinery or workers on site. 

The result? Projects continue with minimal downtime.

Sustainability is a growing priority across industries. Drone surveying contributes by reducing the environmental impact of data collection.

Here’s how:

• Fewer site visits: Less travel for surveyors means lower emissions. 
• Reduced equipment use: No need for scaffolding or heavy machinery. 
• Efficient capture: Drones cover large areas quickly, reducing resource usage. 

In addition, drones provide valuable environmental data themselves – for example, monitoring biodiversity, mapping rivers, or tracking coastal erosion. This makes them an eco-friendly tool in more ways than one.
