Leveraging Drone and Photogrammetry in Advancing Land Management

In Orselina, Switzerland, local authorities aimed to update their cadastral survey records to accurately define land cover and property boundaries. To achieve this, they enlisted the expertise of Studio Calastri, a surveying company based in Ticino. Utilizing drones equipped with a Zenmuse P1 camera, Studio Calastri captured 6,500 images over 3.5 square kilometers of land. The collected data, processed with PIX4Dmatic and PIX4Dsurvey, enabled the extraction of vital elements such as building measurements, roads, and open spaces for comprehensive digital survey analysis.
