What is a drone survey?

A drone survey uses drones to survey landscapes from the air. Capturing a range of visual data such as photography and video. The images captured are tagged with geo-coordinates that are captured by a GNSS sensor on the drone. This data indicates exactly where that image is located in space.

Through processing these images, a photogrammetry software can then create orthomosaics and 3D models, from which it can measure accurate distance, as well as surfaces and volumes of physical objects.


In comparison to conventional surveying techniques, drone surveys are typically considered to be effective. They require less man-power to conduct. Give a greater degree of flexibility with where to shoot from.

At Helidragon, we use cutting-edge UAV technology to carry out inspections and site surveys. Thus, allowing our team provide an innovative and more efficient solution for your site survey needs.

At the heart of our drone survey services lies the ability to collect data rapidly and accurately. Traditional surveying methods are undeniably resource heavy.

They require significant time and manual labour to gather data. Very often, these surveying projects can be held up. This leads to delays and increased costs.


A drone survey provides a much more a streamlined process of site surveying, when compared to traditional methods. Therefore, this drastically reduces the time and resources required. Subsequently, this method guarantees a level of precision that was previously unattainable.

Our team of drone pilots will fly our drones across the designated areas needed. We use our drones to get a full picture of your entire site. From a range of heights, and even from previously inaccessible spots. Drones go where humans can't.

During this flight, we will capture detailed images and video your site, from different heights and angles. We create a database of spatial and visual data, unique to your project. We then use this data to build your site survey report.

How this helps you

Our drone surveys you access to real time data. This enables you to make decisions on your projects quicker. From resource allocation, to risk management.

With our drone survey services, you will gain invaluable insights to help make your projects a success.

What is Aerial Mapping?

Aerial mapping is the process of using drones to capture the intricate details of terrain, structures, and features from above. Rather than people traversing an area with camera equipment. The result, consequently, is a meticulously detailed and georeferenced map. This map showcases the lay of the land with unmatched precision, unlike traditional methods.

Conventional mapping methods often face limitations when it comes to accessing hard-to-reach or expansive areas. Aerial mapping therefore disrupts these limitations. Drones offer a comprehensive view that captures every contour, elevation change, and geographic element. 

The heart of aerial mapping lies in its ability to deliver data accuracy that's second to none. Our drones capture imagery with high-resolution cameras and integrate it with advanced GPS technology. Additionally, this allows us to create geospatially accurate maps that align with real-world coordinates. This level of precision ensures that decisions made based on aerial maps are informed by dependable, up-to-date information.

Benefits of Drone Surveys and Aerial Mapping


Drone surveys are far cheaper than traditional surveying methods. The automation inherent in drone technology eliminates the need for labour-intensive and time-consuming manual surveys. 

This reduction in resource expenditure is coupled with enhanced efficiency. Therefore you get better reports. At a cheaper cost. In a quicker time. Unquestionably - a no brainer.


The use of UAV provides a level of accuracy and data quality that sets a new standard for precision. Our drones capture high-resolution images and spatial data. Unlike with traditional methods, this ensures the minutest details are rendered with clarity. 

This level of accuracy isn't achievable through conventional methods, underscoring the paramount importance of drones in modern data collection endeavours.

In the construction and engineering landscape, precision is paramount. A Drone survey provides real-time site progress monitoring, accurate topographic data, and detailed 3D models. 

These insights streamline project management, enhance safety assessments, and optimise resource allocation, ultimately expediting project timelines and minimising costs.

Agriculture and Land Management

Drone surveying for agriculture

The agriculture sector benefits immensely from aerial mapping's bird's-eye view. Drones enable farmers to monitor crop health, detect irrigation inefficiencies, and manage land more efficiently. 

With data-driven insights, crop yield prediction, disease prevention, and resource optimization become strategic tools in modern farming.

Environmental Conservation:

Aerial mapping helps environmentalists in monitoring habitats, tracking deforestation, and assessing the impact of climate change. 

By facilitating accurate assessments of ecological shifts, drones contribute to informed conservation efforts, ensuring sustainable land and resource management.

Urban Planning and Development:

Cities in transition demand precise information for effective planning. Aerial mapping offers urban planners detailed visualisations of cityscapes. Thus helping to analyse infrastructure needs, traffic flow, and zoning patterns. This aids in designing sustainable, resilient, and well-connected urban environments.

Mining and Natural Resources:

For the mining and resource extraction industry, drone surveys are a game-changer. Firstly, drones provide accurate 3D models of mining sites. This helps operators manage excavation processes and monitor stockpile volumes. Lastly, it helps ensure compliance with environmental regulations.
