Drones in Surveying
Whether for surveying streets, districts, building sites or quarries: for aerial survey, drones normally fly in automatic GPS flight mode over the area in question. Vertical pictures then provide the basis for photogrammetric post-production of the images. A ground resolution of a few cm per pixel helps to meet high demands.
The results are represented and processed as point clouds, volume calculations or cut edges. Somewhat larger UAVs fitted with laser scanners realise the advantages of airborne laser scanning, in particular for the production of digital ground models.
