DJI Phantom

Unmanned aerial vehicles (UAV) are used primarily used in surveillance and control of maritime traffic, construction surveillance, detection and control of coastal hazards, flood monitoring, terrain mapping, fire disasters, remote data acquisition of existing pavement conditions, earthquake damage assessment, and post distress monitoring survey. UAV’s come with high-quality cameras and a global navigation satellite system – making it possible to collect survey-grade data and develop 3D models which can be used be to access pavement distress, rock-cut stability assessment, stockpile volume determination.
