Description

This dataset includes Digital Surface Models (DSMs) derived from UAV-LiDAR imagery acquired during the SnowEx 2021 field campaign at the Central Agricultural Research Center in central Montana (USA). The DSMs are at 0.3 m resolution and consist of one snow-off and seven snow-on flights. Also available is a 0.25 m resolution orthomosaic of the study area collected via UAV on 21 January 2021.
