This dataset contains orthorectified surface reflectance imagery in 326 bands (397 to 1000nm) and derived plant functional type (PFT) classification products generated from Unmanned Aerial Vehicle (UAV)-mounted Visible and Near-Infrared (VNIR) imaging spectrometers. The imagery were collected across multiple Arctic and boreal sites in Alaska during July and August of 2018 and 2019. The data are high spatial resolution (approximately 4-10 cm ground sampling distance) hyperspectral imagery processed to generate spatially explicit maps of PFTs at native UAV resolution. The data were collected as part of the NASA Arctic Boreal Vulnerability Experiment (ABoVE) and are provided in GeoTIFF, Keyhole Markup Language, and ENVI formats along with JPEG quicklook images.
