Research questionHow can individual-tree species be classified from multispectral airborne laser scans when field references are scarce?Individual-tree species classification from airborne laser scanning depends on reference-labeled data, but public multispectral scans paired with high-quality field identifications are limited. This constrains the development and comparison of classification methods.

Latest papersRecent research connected to this question, newest first.Multispectral airborne laser scanning dataset for tree species classification: MS-ALS-SPECIESThe source describes an open dataset of 6,326 segment-level point clouds representing nine tree species in southern Finland. Data were collected with two multispectral laser-scanning systems operating at three wavelengths, with point densities above 1,000 points/m² and approximately 35 points/m²; a crowdsourcing application supports field reference collection. The evidence covers dataset-based analyses and benchmarking support, not performance beyond the represented species and region.research paper · Sep 2, 2026
