Land Surveying Drones
Land surveying can be tough work, requiring the ideal tools, dedicated time in the field and a lot of effort spent compiling the data.
The problem with this hands-on approach is that not only is it time-consuming, it can affect accuracy levels.
Companies are now looking at surveying drones and LiDAR to approve the accuracy of their methods and data, and the efficiency of their work.
What are the advantages of using these land surveying drones over traditional techniques?
Many companies are sure to look towards UAVs for land surveying because of the potential time that can be saved, the costs that can be cut and the safety implications that are offered.
But there is one other advantage to drones that cannot be overlooked: drones are just more accurate than humans.
This accuracy can be seen in two ways:
- the accuracy of the process
- the accuracy of the data
Carrying out land surveying the old-fashioned way – on foot with lots of equipment – can be problematic.
Not only do employees have to spend the time and effort mapping out every possible quadrant and hoping that there is enough power for the tools, they have to cover as much ground as possible for an accurate representation of the landscape.
This is too much to ask of a process that is subject to human error and can often take place in difficult terrain.
Drones help users get around this issue by covering all necessary areas and having the ability and accuracy in the programming to map out everything. The only potential obstacle is the battery life of the unit.
The accuracy of the data that is then created is ensured through high-end technology that keeps on advancing.
The drones are able to map out wide areas in fine detail thanks to 3D scanners, high-resolution cameras, and other tools that can create layered images of the terrain.
The sharper the image and the smarter the drone, the greater the chance of producing all the necessary data in a short space of time.
This accuracy of data in land surveying drones could be improved with LiDAR.
LiDAR is a relatively new advancement in terrain scanning technology, but it is one that has excited many in the field.
The opportunity to pair this system with a high-end surveying UAV just increases that appeal. LiDAR stands for Light Detection and Ranging technology.
This basically means that thousands of lights are bounced off the surface of a given area to create an image of the terrain beneath.
This method is clearly only suited to being used from an aerial approach, which has been problematic in the past due to the need for a careful approach in a manned vehicle.
Adding LiDAR to an unmanned aerial vehicle widens the potential for this system, and most likely the accuracy levels too.
There is still some work to do before land surveyors can properly utilize these unmanned drones and LiDAR, and some legislation to pass, but there are high hopes that this interesting partnership will come to be the norm in land surveying, with companies enjoying more accurate results.
