RTK and PPK are two positioning methods used in professional drone mapping. They both help improve the accuracy of drone data, but they do it in different ways. RTK corrects positioning during the flight. PPK corrects positioning after the flight. That simple difference affects workflow, reliability, setup, processing, equipment choice and how mapping data is […]

Photogrammetry and LiDAR are two of the most important technologies in drone mapping. They can both be used to create 3D data, maps and models, but they work in very different ways. Photogrammetry uses overlapping photographs. LiDAR uses laser measurements. That simple difference affects almost everything: cost, equipment, accuracy, vegetation performance, file outputs, workflow, software,

Drone mapping is one of the most useful professional applications of drone technology. Instead of using a drone just to take attractive aerial photos or video, drone mapping uses overlapping images, sensor data and specialist software to create measurable maps, models and datasets. That is what makes it different from normal drone photography. A single
