+# `lidaRtRee` tutorials
+
+`lidaRtRee_tutorials` is a repository that provides tutorials for forest analysis with airborne laser scanning (ALS or lidar remote sensing) data, using functions from `R` packages [lidR](https://github.com/Jean-Romain/lidR/) (also available on [CRAN](https://cran.r-project.org/web/packages/lidR/index.html)) and [lidaRtRee](https://gitlab.irstea.fr/jean-matthieu.monnet/lidaRtRee). Tutorials are available as `Rmarkdown`, `html` and `pdf` files. Datasets useful for code running are also provided.

 This workflow compares a canopy height model (CHM) derived from airborne laser scanning (ALS) data with tree positions inventoried in the field, and then proposes a translation in plot position for better matching. The method is described in @Monnet2014. Here it is exemplified with circular plots, but it can be applied to any shape of field plots. The workflow is based on functions from packages `lidaRtRee` and `lidR`. Example data were acquired in the forest of Lac des Rouges Truites (Jura, France).

 The R code below presents a forest structure metrics computation workflow from Airborne Laser Scanning (ALS) data. Workflow is based on functions from packages `lidaRtRee` and `lidR`, packages `vegan` and `foreach` are also required. Metrics are computed for each cell of a grid defined by a resolution. Those metrics are designed to describe the 3D structure of forest.
 Different types of metrics are computed:
