The SPEC Lab's Global Ecosystem Structure Index (GESI) integrates detailed information on the vertical distribution of plant structure derived from the satellite waveform lidar system (GEDI) to create wall to wall high-resolution (10-30m) maps of ecosystem structural diversity at a global spatial scale. GESI is integrated in the SPEC Lab's GeoPlot workflow, and also used in various collaborations, such as occupancy modelling of species distributions in the Amazon.
