G-LiHT
Goddard’s LiDAR Hyperspectral & Thermal Imager

The Goddards’ LiDAR Hyperspectral & Thermal Imager (G-LiHT) is a portable, airborne imaging system developed at Goddard Space Flight Center. It uses multiple sensors to simultaneously map terrestrial ecosystems' composition, structure, and function. G-LiHT consists of a scanning lidar, profiling lidar, irradiance spectrometer, imaging spectrometer, and a thermal camera. The scanning lidar operates at 1550 nm wavelength and has a swath width of 387 m, while the profiling lidar operates at the 905 nm wavelength. The irradiance spectrometer has a spectral range of 350-1,100 nm and an acquisition rate of 1 Hz, while the imaging spectrometer has a spectral range of 420-950 nm and an acquisition rate of 50 Hz. The thermal camera has a spectral range of 8-14 μm, a swath width of 173 m, and an acquisition rate of 25 Hz. Data products from G-LiHT have a spatial resolution of 1 meter.
