This data repository contains country-wide data products for the ecosystem structure metrics generated from Airborne Laser Scanning (ALS) data across the Netherlands (AHN4). Twenty-five ecosystem structure metrics(at 10-meterresolution, GeoTIFF format) were derived from the AHN4 dataset ( https://www.ahn.nl/ahn-viewer ) using Laserfarm workflow ( https://zenodo.org/record/5636773 ). Laserfarm is a free and open-source workflow thatenables efficient, scalable, and distributed processing of multi-terabyte LiDAR point clouds from national and regional ALSsurveys into LiDAR metrics of ecosystem structure. All code of Laserfarm is hosted and freely available on GitHub ( https://github.com/eEcoLiDAR/Laserfarm ). Note that we also published the data products generated from AHN3 (2014-2019), which you can find in the repository here: https://doi.org/10.5281/zenodo.6421381 . Laserfarmworkflow was also employed to generate the data products from AHN4 (2020-2022). The twenty-five LiDAR metrics are related to three key dimensions of ecosystem structure (ecosystem height, ecosystem cover, and ecosystem structural complexity). Each GeoTIFF layer represents one LiDAR metric at 10 m resolution covering the whole Netherlands (file name as "ahn4_10m_featrue_name.tiff"). A detailed description of all the metrics can be found in the README file (README.pdf).
