G-LiHT

Goddard's LiDAR, Hyperspectral and Thermal Airborne Imaging System

The Goddard Space Flight Center's LiDAR Hyperspectral and Thermal (G-LiHT) portable airborne imaging system consists of a scanning lidar, profiling lidar, irradiance spectrometer, imaging spectrometer, and thermal camera.

G-LiHT enables data fusion studies by providing coincident data in time and space, and provides fine-scale (<1 m) observations over large areas that are needed in many ecosystem studies.

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.
