Drone Surveys: What Are They and How Do They Work?

August 18, 2021 10:06 am Published by

Drone surveys are a faster, safer and more cost-efficient way to survey at height. Drone surveys are an increasingly popular method of surveying from the air, and are fast becoming the sensible choice for engineers and construction companies as they offer great advantages in terms of safety and speed of access.

If you need to effectively collect data from an out of reach place or an inaccessible area, like railways, motorways, dilapidated structures or small islands, then a drone survey is the perfect solution for your surveying needs.

How does a drone survey work?

A drone survey can only be carried out by a highly skilled and fully insured CAA approved pilot.

The drone will be controlled the entire time, from the air to the ground, to ensure crystal-clear photography or videography is recorded at all times. The footage and imagery being surveyed is immediately transmitted to the operative’s smartphone or tablet for inspection, so all data can be viewed and reported on in real-time. It also enables clients to receive comprehensive results on a real-time basis.

What kind of information can a drone survey provide?

Completing work that originally would have been completely impossible in the past, drone survey services are able to conclude first-class results and a comprehensive inspection of any given site. The latest drone technology can provide clients with the following information, including:


Construction progress monitoring

Condition surveys

Monitoring for marine, coastal or flooding

Documentation of Heritage buildings and structures

Field inspection and crop monitoring


GPS position

With the ability to reach the most inaccessible, hazardous or large-scale sites, the team at South West Surveys will use the latest drone technology to provide you with a wide range of drone surveys and inspections – all in a fraction of the time taken by traditional surveying methods.



What drones are used for drone surveys?

This will differ from company to company, but at South West Surveys, we use high quality 20mp or 100mp cameras to provide a set of JPG images. The high quality imagery can also be supplied as rich 3D point cloud; this is useful for showing sites in their entirety, or to complete point cloud datasets where a terrestrial laser scan cannot reach.


We also use thermal imaging cameras, which can report on the performance of solar panels and report any heat loss incurred by roofs on residential properties or commercial buildings.
