Drones are very rarely out of the news these days, often for nefarious reasons. The sad thing about this is that people fail to see the huge amount of good that they are doing, the lives they are saving and the industry’s that they are revolutionising. One of these industries is land surveying.
The benefits of using drones for land surveying are so numerous that I won't go into all of them in detail, but here are just a few to give you an idea of where you can win.
Time is money, and when using a drone for surveying you will definitely be saving time. Drones can cover a huge area, in next to no time, the time it would take human hours to cover. Drones don’t get tired, and they don’t make the mistakes humans do when they get tired!
Drones Can Go Where Humans Cannot
There are some areas in need of regular surveying that are either unsafe or just plain hard to get to. For a human, but not for a drone. Think of swampy marshland, densely wooded areas or even areas that may contain unexploded ordnance. A drone can map these areas, quickly accurately and safely.
Faster Data Acquisition and Improved Data Density
A drone can cover a large area in a far more efficient manner and at a lower altitude than a plane or a helicopter, meaning that more detail can be captured and at a much lower cost.
Tracking and Monitoring Changes in the Landscape
If a large construction, conservation or research project needs accurate data on a large parcel of land, drones can generate highly accurate 3D maps using packages such as Pix4D or DroneDepoy. These can be used to monitor and track changes in the landscape over time, and accurately measure any changes
Other uses can include:
• Earthwork volume measurement
• Elevation Mapping and Assessment
• Surface assessment for drainage models
• Thermal surveys
The list is very long, and those who are embracing this fantastic technology are already embracing the rewards.
