Is Drone Surveying Right for Your Project? Key Benefits Explained

The surveying industry has had a massive digital shift over the last decade. While traditional methods remain the foundation of surveying, Unmanned Aerial Vehicles (UAVs), commonly known as drones, have introduced a new perspective on what was previously impossible or too expensive for businesses.

Now, drones are much more accessible, and it is important to be educated on how beneficial they can be for your project.

If you are managing a project, you might be wondering if an aerial approach is a gimmick or a genuine necessity. At South West Surveys, we look at the benefits of drone surveying and how to determine if it’s the right fit for your site.

What Are Drone Surveys? Understanding the Drone LiDAR Survey

Unlike standard aerial photography, drone surveying can create highly accurate maps, 3D models and topographical charts that align with the real-life coordinates. The drones are equipped with specialised sensors (like high-resolution cameras for photogrammetry or laser scanners for LiDAR), which allow them to do this.

The real power and results from drone surveying are from the transition of raw imagery into actionable data. While a standard drone might take a clear photo, a surveying drone captures hundreds or thousands of images to use for photogrammetry. These images can create a point cloud, which is a dense collection of millions of data points.

Alternatively, when equipped with LiDAR, the lasers which the drone emits can see through dense vegetation or tree canopies, providing an accurate topographical map of the terrain.

The Primary Benefits of Professional UAV Mapping

The core advantages of utilising this technology focus on speed, safety, and data depth:

• Efficiency: One of the most immediate advantages of drone surveying is the significant reduction in time spent on-site. A traditional grounds crew could have taken days or weeks, depending on the size of the project. A drone can capture the same volume of data in a matter of hours.
• Improved Safety: Surveying often involves navigating hazardous environments. Using aerial technology removes the need for people to enter high-risk areas. As well as this, it minimises the need for costly site closures or specialised access equipment such as scaffolding.
• Superior Data: Beyond speed and safety, the drones provide an extraordinary level of data that traditional methods cannot easily replicate.

Is an Aerial Land Survey Right for Your Project?

When determining whether a land survey using drone technology is required, consider the following key factors:

Project Scale

Determining if drone surveying is necessary often comes down to the total size of the site. For very small residential plots or internal room measurements, traditional ground-based surveying is likely to be the most practical approach.

Site Accessibility

The physical nature of the terrain is a major factor. If your project involves hard-to-reach or hazardous areas, a drone is often the only safe way to gather data. It could be a fragile roof, steep quarry surface or busy infrastructure, and a drone will be able to safely operate despite this.

Define Your Data Requirements

Finally, think about the end product that you are looking for. If your team needs a full 3D digital copy of the area or high-resolution imagery, a drone is going to be the most efficient tool for the job. If your project only requires a few specific boundary points or simple 2D line work, a traditional grounds approach may be all that is required.

Summary: Maximising Efficiency With Drone Surveys

Drone surveying is no longer a futuristic concept. It is a practical tool that provides better data, a safer working environment and more efficient output. For projects involving large land areas, complex topography or hard-to-reach structures, the utilisation of drones is likely the most logical and cost-effective choice.
