G-LiHT: Goddard's LiDAR, Hyperspectral & Thermal Imager
G-LiHT is a portable, airborne imaging system that simultaneously maps the composition, structure, and function of terrestrial ecosystems using:
- LiDAR to provide 3D information about the distribution of foliage and canopy elements;
- imaging spectroscopy to discern species composition and variations in biophysical variables; and
- thermal measurements to quantify surface temperatures and detect heat and moisture stress.
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.
