Country-wide data products for the ecosystem structure metrics derived from ALS data across the Netherlands (AHN3)

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 one additional layer of point density is also provided. Each GeoTIFF layer represents one LiDAR metric at 10 m resolution covering the whole Netherlands (file name as "ahn3_10m_featrue_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:
