Session: : Scaling-up Demography Using Remote Sensing

INS 5-3 - Continental-scale hyperspectral tree species classification in the United States National Ecological Observatory Network

Tuesday, August 8, 2023
10:00 AM – 11:30 AM PDT
Location: 251
Advances in remote sensing applications unlock the potential for developing algorithms for species classification at the level of individual tree crowns at unprecedented scales. However, most approaches focus on site-specific applications and a small number of taxonomic groups. Is it possible instead to generalize to broader geographic areas, taxa, and ecosystems? Leveraging data from NEON, we compared the performance of a continental-extent model trained on 27 NEON sites (77 species) against models trained from individual sites, evaluating advantages and challenges posed by training species classifiers at a wide range of US terrestrial ecosystems.
