UAV Photogrammetry as an Alternative to Classic Terrestrial Surveying Techniques
Why are UAVs increasingly supplementing or even replacing terrestrial survey methods for many applications? This article explores the advantages of photogrammetric mapping with UAVs.
Unmanned aerial vehicle (UAV or 'drone') mapping often uses photogrammetry to generate accurate, real-world 3D models from 2D imagery. By combining and processing multiple georeferenced aerial images, photogrammetric techniques are used to generate outputs such as 3D point clouds, raster digital elevation models, and orthomosaics.
One of the biggest advantages of photogrammetric mapping with UAVs is that it allows land surveyors to accomplish more in less time. Surveying jobs that would typically take weeks to complete can be finished in a matter of days with UAVs. As such, using UAVs can prove to be significantly cheaper for many projects.
