Harmonized terrestrial laser scanning forest dataset: 3D point clouds and tree-level attributes from five campaigns in Europe

The main component of each campaign is a set of high-resolution (1 cm) 3D point clouds representing 50 m × 50 m forest plots acquired with a RIEGL VZ-400i terrestrial laser scanner. In addition to the point clouds, each campaign provides standardized supplementary data, including scan position shapefiles, plot boundary polygons, tree-level attribute data (DBH, height, species class), preview images, and a comprehensive metadata overview table.

All five sub-campaigns follow the same acquisition protocol, processing workflow, file structure, and naming convention. Each campaign is published as an individual Zenodo record and can be downloaded separately.
