Terrestrial laser scanning point cloud (Riegl VZ-400i) from a managed Scots pine stand in the Evo test site, November 2022

Abstract

Terrestrial laser scanning point cloud from a managed Scots pine stand located in the Evo test site. The point cloud data was acquired in November 16, 2022 using a Riegl VZ-400i time-of-flight terrestrial laser scanner operating at a 1550 nm wavelength and providing 100° vertical and 360° horizontal field of view. The scanner was operated at a pulse repetition rate of 600 kHz that enabled recording up to 8 returns per each emitted laser pulse. The applied ‘Panorama 40’ scan pattern featured an angular resolution of 0.04° and a point spacing of 3.5 mm at a 10-m distance. The multi-scan setup consisted of 23 scans distributed around the forest stand favoring locations with direct visibility to the treetops, considering the 100° vertical field-of-view of the scanner. While acquiring the scan data, the scanner provided automatic pose estimation based on built-in GNSS (global navigation satellite system) and IMU (inertial measurement unit) sensors. This enabled automatic on-board co-registration of the individual scans without the use of external reference targets. The raw scan data from individual scans were converted to point clouds that were co-registered and merged in a RiSCAN PRO processing software (version 2.14.1) provided by the scanner manufacturer.

The dataset is provided by the ScanForest research infrastructure (www.scanforest.fi) and UNITE flagship (www.uniteflagship.fi) funded by the Research Council of Finland.
