Terrestrial laser scanning point clouds acquired in the autumn of 2019 from 37 sample plots located in Evo, Finland. A Leica RTC 360 A 3D (Leica Geosystems, St. Gallen, Switzerland) time-of-flight laser scanner was used in the data acquisition. A multi-scan approach has been applied in the data acquisition, that is, each sample plot has been scanned from five separate scanning locations: one scan from the plot centre and four scans from quadrant directions (i.e. north-east, south-east, south-west, and north-west of the plot centre). Individual scans have been co-registered using artificial reference targets whose exact locations have been measured using real-time kinematic GNSS. Topography has been removed from the point clouds by normalizing the Z-coordinates to heights above the ground using LAStools-software (http://rapidlasso.com).
