UAVs operate between our human scale of landscape observation and that of low-flying aircraft, that is between ground level & 120m. When combined with appropriate receptors to record survey data and the software to process it, this combination hits the ‘sweat-spot’, quickly capturing and processing cost-efficient, high quality, survey data.
UAV systems
are relatively inexpensive to commission, and with the low ground sample distance (GSD) of c.1cm/pixel (Inspire 1 Pro at 50m) they can be deployed rapidly giving a high temporal resolution (time in between repeat surveys). When utilised with photogrammetry software, even mid-range UAV systems can out perform other techniques in their ability to generate high-resolution topographic data for use in topographical surveys, 2D and 3D modelling, flood risk assessment, habitat surveys, and many additional applications.
