Aerial Surveying Revealed: Applications and Advancements

Surveying has long been a vital part of land development projects. Accurate surveys let us understand the land we’re working with in a more precise and calculated way, and is crucial for designing and building sturdy structures that are made to last. 

Aerial surveys have proven to be a key aspect of modern surveying. This method offers astounding advantages in terms of efficiency, accuracy, scope and more, making it a great choice for surveyors and land developers who value accurate results.

What Is Aerial Surveying?

Aerial surveying involves capturing detailed information about a plot of land from an elevated height, usually by utilising drones and scanners. Drones can be used in tandem with technology such as sensors, cameras and aerial LiDAR (Light Detection and Ranging) to collect data while being piloted by experienced surveyors who remain in a safe location. 

Aerial surveying can be extremely beneficial and efficient for land development needs. Particularly, here are two key points regarding land development:

• Cartography And Land Mapping. Aerial surveying plays a very important role in creating accurate maps and charts used for urban planning, land development, infrastructure design and more. High-resolution aerial imagery and LiDAR data enable the creation of detailed topographic maps, cadastral surveys and 3D terrain models. This data and the resulting maps and models make it easier for architects, engineers and others to have a clear view of the land or structure they’re working with, allowing them to tailor their designs or plans to ensure their work is strong and reliable. While this data could be captured by traditional surveying methods, drones and scanners speed up the process without losing quality or accuracy.

• Infrastructure Inspection. Aerial surveying is instrumental in inspecting critical infrastructure assets such as pipelines, power lines, bridges and railways. It allows for the detection of defects, corrosion, encroachments and other structural issues without the need for ground-based surveys. Just like the point mentioned above, using drones can hasten the process as well as make the task safer for the surveyors involved.

Aside from land development and infrastructure projects, aerial surveys can also be used for a wide variety of other applications, such as monitoring environmental changes like deforestation. 

Amazing Advancements In Aerial Surveying

Recent advancements in aerial surveying technology have further enhanced its capabilities and efficiency, making it even more of a viable option for New Zealand developers who want accurate results for their projects. A few notable advancements are:

High-Resolution Imaging. Better and more capable cameras have led to the development of higher-resolution aerial cameras, which can take detailed images to provide even more clarity and detail. These high-resolution images make it easier to clearly understand a picture, lessening the chance of mistakes made. 

LiDAR Technology. LiDAR systems have become increasingly compact, lightweight and cost-effective, making them more accessible and useful for surveyors. LiDAR sensors mounted on aerial platforms can generate accurate elevation models, 3D point clouds and digital terrain models with an impressive level of accuracy.

Advanced Data Processing And Analysis. Higher-quality computers and software tools have streamlined the processing and analysis of data collected from aerial surveys, meaning even the analysis phase of the process can be faster and more accurate. Automated algorithms for photogrammetry, point cloud processing and machine learning enable rapid data interpretation, feature extraction and decision-making.

Choosing Your Aerial Surveying Company

Drones equipped with the right technology can provide amazing results and accurate data. However, they are tools, and tools are best utilised when in the hands of those who know how to use them well. How can you find the best aerial surveyors for your needs? Pay attention to these qualities:

Experience And Expertise. Hands-on experience goes a long way. Choose surveyors who have a history of successful aerial surveying projects. Additionally, be sure you ask them if they have experience with your specific kind of project.

Modern Technology And Equipment. Ask your potential surveyors about the kinds of equipment they use. Do they use drones with advanced sensors and scanners? What kind of software do they use to analyse the data they collect? They should have the proper tools to provide you with the results you need. 

Safety. Above all else, your surveyors should prioritise safety for themselves as well as for your team. Fortunately, drones can help make surveying tasks safer because the surveyor can remain in a safe location while they pilot the drone. Still, your surveyors should understand how to conduct themselves safely while completing their tasks.
