This tutorial presents a workflow to optimize the coregistration of field measurements of tree positions with Airborne Laser Scanning (ALS) data. A precise coregistration is a necessary to avoid border effects leading to errors in models, e.g. when calibrating area-based models for the prediction of forest parameters.
The following files are provided:
- Rmarkdown source,
- Field plot coregistration tutorial in html,
- a bibliography file
- datasets required to run the source code are also available on the repository.
