High-resolution (1m) vegetation structural metrics derived from the fourth Dutch national ALS survey (AHN4) within Natura2000 sites in the Netherlands

General information

This repository contains a set of GeoTIFF layers of vegetation structure derived from the AHN4 point cloud for Natura2000 sites in the Netherlands. The spatial resolution of the raster layer is 1 m. 

A detailed description of the processing pipeline is provided in Readme.docx.

An example map of the LiDAR metrics (i.e. the 95th percentile of vegetation height) within Natura2000 sites is provided in Natura2000_Hp95.pdf.

More details on metric calculation are provided on GitHub (Laserchicken: https://github.com/eEcoLiDAR/laserchicken and Laserfarm: https://github.com/eEcoLiDAR/Laserfarm), as well as on the “Laserchicken” documentation page (https://laserchicken.readthedocs.io/en/latest/).
