Photogrammetry refers to the process of using aerial photography or videography to create models from real-world data. The model can then be used by a client or scientist to evaluate the accuracy of their original model in a real-world setting. The best drone for photogrammetry is one that is capable of capturing high-quality images, as well as good video footage. For this purpose, you’ll need a drone that can fly at a steady speed and hover over its subject for long periods of time without losing its connection to the ground.
