The Interring Facts about Land Surveying Using a Drone

The same was as the carpenters started using electric drills and woodworkers using robotic saws, land surveyors now use drones to bring more perfection to their work. It is a fact that professional technology tools can get better results in lesser time, with more precision.

The new-age surveyors find that the mapping drones can be a perfect support, especially in difficult surveying tasks. There are advanced self-piloting drones available now, which are custom designed for surveying purpose by eliminating many risk factors previously involved in manual surveying.

The major advantage of using a drone for land surveys is that it can take off easily from a safe location and can be managed using a remote control. This can be managed easily from the land booths and once the task is over, it can be landed back on comfortable. Real time viewing through the drone cameras and other surveying equipment too is possible from the land.

Drone technology for surveying

As we can see, land surveying methods and technology have grown multifold over the last couple of decades. There were electronic distance meters introduced at first, then came GPS, total station, robotic technology, and laser-based scanner etc. it can be said that the unmanned aerial vehicles (drone) are the sixth generation in technology-enabled land surveying.

At the initial stages, drones were not much compatible to be used in land surveying and remote sensing type of tasks. But, with the advent of more practical solutions like lightweight polymer batteries and low-cost technology along with lightweight cameras and oblique close-range aerial photography methods, the future of land surveying using drones seems to be so bright.

Types of drones used in surveying

Basically, there are two types of drones used in surveying as

1. The fixed-wing drones with brushless electric motor. In this, the rotor units will enable the drone to hover at a very precise altitude and such drones can position correctly by themselves and operate in a very confined airspace.

2. The basic eight-engine multirotor drones consist of a very lightweight airframe, which may look like a spider with a motor at each leg. These drones are powered by light weight lithium-polymer battery and functions with the assistance of a small device named electronic speed controllers (ESCs).

Technology of all types of modern drones are based on the light weight polymer batteries which can store enormous amount of power. The brushless motor technology can attain a large range of variable speeds. These drones are very simple, easy to hand hobby-type airplanes with radio controlled functional mechanisms. Additional altimeters and GPS are used to enhance their functional capabilities. The operators on earth can digitally fly along by using digital video headsets by viewing the clippings from the on-board digital cameras through micro-video transmitters.

Survey drone software

There are a lot of new software packages available for drone in terms of navigating, video capturing, editing, combining etc. The latest photogrammetry software are capable of producing 3D survey images optimum accuracy, which are far better than the conventional aerial photography.
