While surveying with drones, images of the ground are taken from multiple vantage points. Through processing these images, a photogrammetry software can then create orthomosaics and 3D models, that it could measure accurate distance, together with surfaces and volumes of physical objects.
Data outputs from the drone
Images taken by the drone are often saved on a memory (such as Sdcard), just like for any other camera. With respect to the technology utilized by the drone, the images are already geo-tagged or can be imported in a geo-tagging software, such as WingtraHub. In line with the size of the survey site, you almost certainly have between a couple of hundred images and some thousand, and each image contains geographical information (X, Y, Z).
Importing right into a photogrammetry software
After importing or uploading the geo-tagged images in a photogrammetry software such as Propeller, Bentley ContextCapture or Pix4D, images will be stitched together to create 2D or 3D types of the surveyed site. http://www.landsurveyorsgloucestershire.uk/best-drone-surveying-gloucestershire/ could be a lengthy process depending on amount of images and the performance of one's computer. Some photogrammetry software are desktop-based, thus requiring robust hardware. Other software is cloud-based, employing powerful servers rather than your neighborhood computer to process the info.
