We start with a topographic survey to identify the points needed for geolocation using the total station. Once we got the supporting photo points (PFAs) we can start photographing the building using a drone (Phantom 3 Pro - in this specific case). For the photos we have chosen a circular flight around the house, a solution that seemed more appropriate than a flying camera with a nadiral position. Once we have collected all the necessary photos, we have processed them using Agisoft Photoscan.
