Drone aerial mapping refers to the process of using drones (or Unmanned Aerial Vehicles, UAVs) equipped with cameras or other sensors to capture aerial imagery or data, which can then be processed to produce detailed and accurate maps or three-dimensional models of the surveyed area. Here's how drone aerial mapping generally works: Flight Planning: Before a drone takes flight, a flight plan is designed using specialized software. This plan specifies the drone's flight path, altitude, speed, and the overlap of images to ensure comprehensive coverage of the area of interest. Data Capture: As the drone flies over the target area based on the flight plan, it captures a series of high-resolution images or other sensor data. The overlap of images ensures that there are multiple perspectives of each point on the ground, which is crucial for generating accurate 3D models. Data Processing: Once the drone has captured the necessary data, the images are uploaded to a computer. Using photogrammetry software, the images are stitched together to create a cohesive and georeferenced map. This software can also transform the overlapping images into detailed 3D models. Map/Model Production: After processing, the result can be a high-resolution orthomosaic map (a map where every point is georeferenced and can be measured accurately), a 3D model, a Digital Elevation Model (DEM), or a Digital Terrain Model (DTM), among other outputs.
