A drone survey refers to the use of a drone, or unmanned aerial vehicle (UAV), to capture aerial data with downward-facing sensors, such as RGB or multispectral cameras, and LIDAR payloads.
Drone maps created using good quality drone equipment, careful flight planning, commercial grade GPS ground control points and commercial grade processing software can potentially be accurate to around 2-3cm horizontally and around 5-6cm vertically.
With their ability to capture data from above, drones have been successfully integrated into surveying workflows to perform land surveys, photogrammetry, 3D mapping, topographic surveying, and more. … Capturing data with a drone is up to five times faster than with land-based methods and requires less manpower.
Drone surveys are now established as a valuable approach to transmission tower and powerline surveying. By eliminating manual ‘at-height’ working, they greatly reduce risk and improve safety outcomes. Drones can be deployed rapidly and allow asset managers to interrogate defects using ultra high definition 4k imaging.
Pirie Consultants Ltd are one of the few companies in the Manawatu region that use Drone Surveying, Our surveyors are very skilled with using the Drone and have used it on many of our projects.
