Mapping & Survey

Surveying large areas are currently performed using conventional methods like manned aircraft or satellites. These methods are very costly and also produce medium resolution images. Thus the surveyors and map builders are always left wanting for more.

The dawn of drone era is a game changer. The surveying drones fly at a lower altitude and hence able to capture better and produce high resolution images. Drones equipped with RGB cameras, multi-spectral cameras and LiDAR payloads capture and collect respective data and relay it to the central unit. The capture images and data are composite together to give a finished map in digital format with finer details.

Low Cost and Time Investment: As the cost of operations for drones is lower than the conventional methods vis-à-vis satellite or manned aircraft, the former are fast replacing the latter. It would be worthy to note that the cost of drone based surveying and mapping is upto 10 times lower than the conventional methods. Also, the drones in action are up to 5 times faster than the current mainstream surveying and mapping methods.

High Accurate Mapping: Drone surveying and mapping is accurate. Since drones fly at lower altitude they can capture high resolution imaging and detail out centimetre level data. Mapping accuracy for drones is generally accurate on 1:1000 scale. Drones also capture data and build precious 3D geographic information. This information is then put to multiple uses.

Map hard-to-reach places: Drones are highly manoeuvrable and can hover at precarious heights to collect data. Hence the drones that are specially built for topographic survey allow surveying teams to collect extensive and highly reliable data from the inaccessible location and hazardous terrain. This data is used by the surveying team to build highly accurate 3D models without putting ground surveying teams in harm’s way.
