Drone mapping accuracy involves how closely a drone's measurements match the real world's dimensions. It's vital for precise surveying in construction and agriculture. Mapping accuracy has two main components: horizontal accuracy and vertical accuracy. Horizontal accuracy measures how close a location on the map is to its true position on Earth, while vertical accuracy assesses the elevation data's precision. Using advanced drones like the DJI Matrice 350 RTK, achieving high mapping accuracy becomes feasible.
Relative accuracy and absolute accuracy are key in drone mapping. Relative accuracy refers to how precisely objects are positioned relative to each other in a generated model, like an Orthophotomap, Digital Surface Model, or 3D point cloud. Absolute accuracy measures the difference between the model's object's location and its actual position on Earth or in a geodetic coordinate system.
