3D mapping and aerial surveys have become a necessary aspect of effective agricultural management. For example, it can aid with the implementation of effective irrigation systems and monitoring crop yields without having to spend excessive resources on these once time-consuming tasks.
Construction & Structural Maintenance
An SUA-based approach such as aerial LiDAR offers a viable method of capturing data on inaccessible surfaces and complex structural geometry. When it is necessary to capture the accurate topography of existing structures and built-up areas (as well as aiding with retrofitting and refurbishment projects) aerial surveying systems offer a compelling solution.
Whether it's monitoring for changes in landmasses or surveying bodies of water, aerial surveys are playing and increasing role in helping us understand and manage the world around us. Use cases within this field include Hydrological and Coastal Monitoring, Geological Applications such as the mapping of mountainous regions and even Archaeological Site Surveys.
Industrial & Energy Surveys
Large-scale industrial projects require frequent surveys to ensure efficiency and safety. The use of aerial platforms to carry out this preventative maintenance offers the ability to reduce the time spent and achieve more accurate results from a range of viewpoints which weren't previously viable.
AN INTRODUCTION TO AERIAL MAPPING & SURVEYS
SUAs have had a massive impact on the way aerial surveys and mapping are performed. They have proved themselves to be hugely beneficial to these specific workflows with the ability to capture stills with accurately predefined overlap percentages and remain steady at predetermined elevations to ensure data accuracy which would be hugely challenging for a manned aircraft.
There is also the fact that SUAs are an affordable, easily transportable option when undertaking mapping or surveys. This is very important when considering work in challenging environments with tight timescales. Having researched this industry, we've identified the two main approaches used to conduct these tasks:
Photogrammetry uses a collection of stitched-together stills to conduct measurements. This approach is best suited for mapping or surveying bare earth regions. When used by an experienced operator, the Photogrammetry method can produce highly accurate 3D models. Low outlays for software and equipment have also gone some way to making it the most common process for surveying.
Unlike Photogrammetry, LiDAR uses lasers and light to carry out measurements which makes it ideal for heavily vegetated areas or sites with numerous obstructions and obscurants. Aircraft mounted with LiDAR systems can map areas quickly, affordably and with few logistical issues. Additionally, SUA LiDAR solutions offer unique perspectives and in-depth image control which aren't possible with traditional capture methods. They offer flexible configurations, allowing them to gather masses of data and imagery that are perfectly suited to mapping and surveys.
Of the two methods, LiDAR arguably achieves the most accurate results. However, there are limitations on obtaining high-resolution images from the acquired data. Photogrammetry and other photo-based approaches are often used in tandem with LiDAR data to reach the most accurate results through their combined data capture.
Platforms & Products
Heliguy is a licensed DroneDeploy supplier which means that we're able to provide you with the software and support you need to get the most out of this powerful solution.
DroneDeploy is an intuitive solution used to create aerial maps and 3D models. Using their mobile app - which is available on both Android and iOS - it's possible to transform a range of DJI drones into reliable and powerful mapping tools.
The DroneDeploy app facilitates automated flights from take-off and right through to landing while automatically capturing images that can be uploaded to their software for processing. These stills can be used to create a range of visualised data from 2D maps to 3D models.
If you want to produce accurate 3D models and conduct aerial mapping and surveying that can be used by a range of commercial clients, it's necessary to undergo training on the equipment and software integral to the process.
