True color and multispectral imagery data collected by small unoccupied aircraft systems at the USGS National Crude Oil Spill Fate and Natural Attenuation Research Site, Bemidji, Minnesota, June 2018

The U.S. Geological Survey (USGS) deployed multirotor small unoccupied aircraft systems (sUAS or drones) on June 21, 2018, to collect imagery data documenting site conditions at the USGS National Crude Oil Spill Fate and Natural Attenuation Research Site near Bemidji, Minnesota, USA. True color visible light images were collected across the general study area. Multispectral images in five spectral bands (blue, green, red, red edge, and near-infrared) were collected at two aerial survey heights over smaller parts of the study area.
