Traditional surveying methods can take a few days and sometimes a week. But, with the help of UAV technology, it will take a few hours to complete a survey. Data and imageries collected can be processed on the same day. It will help to take less time in gathering data and take the right decisions.
The acquisition and operating cost of a drone survey is much lower than surveys done using satellites and human-crewed aircraft. The technical requirements for the site and personnel are low, and the daily maintenance is simple. These factors reduce the cost of data acquisition and hence make the system cost effective.
With the help of Drones, it is easy to survey those areas that are otherwise difficult or even impossible to access. Like Cliffs, Rugged Terrain and other regions, where conventional surveying is challenging and sometimes impossible. Drones offer a great advantage.
Some of the essential parameters of surveying are spatial resolution and low altitude multi angle shooting. The spatial resolution can sometimes reach centimeters or even smaller. Accurate digital models and 3D landscape maps are some of the outputs of drones.
Land surveying can be a risky job. Drones eliminate the need for surveyors to explore unknown terrains and will also help avoid survey at high risk places.
