Drone solutions map large work sites to provide detailed, precise data for architects and contractors. With flight planning and 3D modeling software, project teams can easily and rapidly collect the surveying data needed to evaluate large work sites. With their ability to capture data from above, drones have been successfully integrated into surveying workflows to perform land surveys, photogrammetry, 3D mapping, topographic surveying, and more. When surveying challenging terrain, drones make it no longer necessary for human operators to physically access and measure points in hazardous or difficult-to-reach locations. Additionally, while traditional surveying methods require meticulous measurement, preparation, and planning, drones can capture comparable data in dramatically shorter time-frames. In an independent study by DroneDeploy, the DJI Phantom 4 RTK achieved 2 cm relative vertical accuracy and 1.20 cm relative horizontal accuracy.
