Drone survey – eyes in the sky
ScanTech Digital, based in Birmingham and covering the UK, offers a range of land surveying services including drone surveys, aerial surveying, 3D photogrammetry mesh models, aerial inspections of hard-to-reach locations and high-resolution aerial photography and videography for professional marketing media.
Using a drone with a RGB camera, the ground is photographed multiple times from different angles, and each image is tagged with coordinates. Through processing these images, photogrammetry software can then create 3D models and orthomosaics, from which it can measure distances; as well as surfaces and volumes of objects accurately.
