Forest structure metrics mapping

This is an old version of this page. You can view the most recent version or browse the history.

This R tutorial presents a workflow to compute both object-oriented and pixel-based metrics to describe the forest structure from Airborne Laser Scanning (lidar remote sensing) data. Extraction of different types of metrics is exemplified and code for parallelized processing of several ALS data files is provided.

The following files are provided:

Rmarkdown source,
Forest structure metrics mapping tutorial in html,
Forest structure metrics mapping tutorial in pdf,
a bibliography file
datasets required to run the source code are also available on the repository.
