What is G-LiHT?

G-LiHT is a portable, airborne imaging system that simultaneously maps the composition, structure, and function of terrestrial ecosystems using:

  1. LiDAR to provide 3D information about the distribution of foliage and canopy elements; 
  2. imaging spectroscopy to discern species composition and variations in biophysical variables; and
  3. 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.
