Low Altitude Remote Sensing Lab (LARS) (Dr. James Dietrich)
The LARS joins efforts of faculty and students who collect, process, and analyze very-high-resolution imagery acquired by unmanned aircraft systems (UAS) or drone flying at a low altitude. The UAS include a professional fix-wing eBee mapping drone with five cameras (RGB, NIR, RedEdge, Thermal, and Sequoia) that is capable of collecting aerial photographs at a spatial resolution down to 1.5 cm/pixel. The lab also contains a rotary-wing DJI Inspire 1 Pro UAS with a professional camera that can film 4K pictures and HD videos. Important accessories include 2 Onset Hobo pyranometers with data logger that can measure solar irradiance with a range of 0-1280 W/m2 over a spectral range of 300-100nm. The UAV has been used to conduct studies for large-scale photogrammetry mapping, image processing technique validation and improvement, and agriculture and environmental applications.
