We’re excited to announce the initial release of crown maps for 100 million trees in the National Ecological Observatory Network (NEON) with information on location, species identify, size, and alive/dead status. Using NEON’s remote sensing data we’ve been developing computer vision models to locate tree crowns for all individuals visible from above and classify those crowns to species (Weinstein et al. 2019, 2020, 2023; Marconi et al. 2022).
