What is an aerial survey used for?

An aerial survey is a simple way of accessing an overall view of large areas from the air and at height. Commonly, an aerial survey is completed using a drone and this provides a cost-effective way for engineers, construction companies and surveyors to see in great detail the land or property in question.

It is often difficult to carry out a survey because many places or buildings are inaccessible or unreachable such as old buildings, small islands, complex roofs, bridges, or tall structures, but an aerial survey using a drone is the perfect solution.

How Does an Aerial Survey Work?

An aerial survey using a drone can be carried out by a CAA approved pilot who has been given the right training and has the relevant qualifications to undertake the drone flight.

During the process, the drone will be controlled by the pilot from the ground to ensure that the right imagery and videography is captured as required. The imagery and footage are transmitted to a smart device so that they can be inspected, viewed and then reported on in real-time. This means that clients are given comprehensive results that they can then utilise as part of understanding what steps to take next.

What Information is Obtained Using an Aerial Survey?

The great thing about aerial surveys or drone surveys is that they make it possible to obtain information on everything from old quarries to mines as well as dilapidated buildings and transport infrastructure. They are used to analyse the area or look for structural defects or problems as part of ongoing maintenance. As a result, an aerial survey will provide the following information:

Aerial surveys provide the ability to reach inaccessible, large-scale sites and hazardous areas with precision and with the latest technology, it means that the quality of data and imagery is better than ever before. They can be used to quickly and efficiently gather vital information that would have once taken a lot of time using traditional methods.

How Are Aerial Surveys Used?

Across a range of industries, aerial surveys provide an extremely useful method of monitoring areas for construction projects or to manage ongoing maintenance. What makes them so unique is the ability to use them in hard to reach areas, as they provide a clear overview using high-definition images and scans that can be used to inform the planning process for a range of build projects.
They are suitable for progress monitoring while they provide a visual overview of the development of a project or area. They can be used to provide regular reports and updates to ensure that everything is as expected, such as the development progress of a building or the condition of a specific area. A 3D model can also be created and that provides a wealth of benefits over traditional 2D models.

The images can then be used to assess, analyse and manage projects with precision and ease.

How Accurate is an Aerial Survey?

When undertaking an aerial survey using a drone, the cameras have the capacity to capture very high-quality images. With aerial surveys using drones, it is possible to see in great detail more specific information, making it possible to make informed decisions.

The drone will use downward-facing sensors and these have the ability to capture vast amounts of data, rapidly. In many instances, it has been found that drones can collect data as much as 97% faster than manual methods. Using this data, it is then possible to create elevation models, obtain highly accurate measurements and make volumetric calculations.

The information proves vital as it provides valuable insights such as identifying errors or problems while having the ability to monitor project progress and more. This tool is now pivotal and that is why it is being used more and more for land inspections, roof inspections, structural surveys, infrastructure maintenance and for use on construction sites.
