This data repository contains country-wide data products for the ecosystem structure metrics generated from Airborne Laser Scanning (ALS) data across the Netherlands (AHN3). Twenty-five ecosystem structure metrics (at 10-meter resolution, GeoTIFF format) were derived from AHN3 dataset (https://downloads.pdok.nl/ahn3-downloadpage/) using Laserfarm workflow (https://zenodo.org/record/5636773). Laserfarm is a free and open-source workflow that enables efficient, scalable, and distributed processing of multi-terabyte LiDAR point clouds from national and regional ALS surveys into LiDAR metrics of ecosystem structure. All code of Laserfarm is hosted and freely available on GitHub (https://github.com/eEcoLiDAR/Laserfarm). The Jupyter Notebooks for the processing of the AHN3 dataset are available on GitHub (https://github.com/eEcoLiDAR/AHN/tree/main/AHN3). The twenty-five LiDAR metrics are related to three key dimensions of ecosystem structure (ecosystem height, ecosystem cover, and ecosystem structural complexity), and a layer of point density and a layer of building/road/water mask are also provided. Each GeoTIFF layer represents one LiDAR metric at 10 m resolution covering the whole Netherlands (file name as "ahn3_10m_feature_name.tiff"). An overview of all the listed metrics (maps) is also provided in the PDF version (AHN3.pdf). A detailed description of the dataset is available from the following data publication:Kissling, W. D., Y. Shi, Z. Koma, C. Meijer, O. Ku, F. Nattino, A. C. Seijmonsbergen, and M. W. Grootes. 2022. Country-wide data of ecosystem structure from the third Dutch airborne laser scanning survey. Data in Brief: 108798.https://doi.org/10.1016/j.dib.2022.108798 A detailed description of all the metrics can be found in the README file (README.docx). A .zip file is also provided containing all the data for the validation of the AHN3 data products (AHN3_validation.zip).
