What are the different types of aerial drone surveys?


There are several types of aerial drone surveys that can be conducted, depending on the specific needs of the survey.


  • Photogrammetry 
  • Thermal Imaging
  • Multispectral Imaging
  • Inspection Survey


In today’s rapidly advancing technological world, drones have become valuable tools for various industries. Aerial drone surveys, in particular, have revolutionised the way we gather data about landscapes, structures, and more. Angell Surveys, a leading provider of drone surveying services, offers a range of options to cater to diverse surveying needs. Let’s explore the different types of aerial drone surveys they provide and how they can benefit various industries.


What is a photogrammetry aerial drone survey?

One of the most common types of aerial drone surveys is photogrammetry. This technique utilises high-resolution photographs taken from drones to create detailed 3D models of a specific location. By capturing a series of overlapping images from different angles, specialised software processes the data to generate accurate models, point clouds, and orthomosaic maps. Photogrammetry surveys are widely used in industries such as construction, urban planning, archaeology, and environmental monitoring. They provide valuable insights into terrain modeling, volumetric calculations, site planning, and visualisations.


What is thermal imaging and why would it be used?

Thermal imaging involves the use of specialised cameras mounted on drones to capture images based on the heat signatures emitted by objects and surfaces. Thermal surveys provide valuable information about temperature variations, energy efficiency, and potential issues with equipment or structures. This type of survey is particularly valuable in industries such as building inspection, energy auditing, and search and rescue operations. Thermal imaging allows for the identification of heat leaks, electrical malfunctions, insulation problems, and the detection of individuals or animals in low visibility conditions.


Why would multispectral imaging be useful?

Multispectral imaging is an advanced technique that involves capturing images across a range of wavelengths, including visible and non-visible light. By using specialised cameras on drones, multispectral surveys provide valuable insights into vegetation health, crop monitoring, and environmental analysis. Different wavelengths of light can reveal information about plant stress, nutrient deficiencies, disease detection, and water absorption patterns. This data is crucial for precision agriculture, forestry management, and environmental conservation efforts.


How does an inspection survey work?

Inspection surveys using drones have transformed the way we inspect critical infrastructure such as bridges, buildings, power lines, and pipelines. Drones equipped with high-resolution cameras, or thermal imaging cameras can access hard-to-reach areas, providing detailed visual and technical data. Inspection surveys help identify structural damage, corrosion, wear and tear, and other issues without risking human safety or causing disruptions. The ability to collect accurate data efficiently enables timely maintenance and reduces downtime for essential infrastructure.


Overall, aerial drone surveys provide a fast, efficient, and cost-effective way to gather detailed data on a variety of landscapes and structures. Whether it’s photogrammetry,, thermal imaging, multispectral imaging, or inspection surveys, Angell Surveys offers a comprehensive range of services tailored to meet the unique requirements of different industries.
