3D forest height maps with ggplot2 and rayshader in R

In this tutorial, I will show you how to use ggplot2 and rayshader in R to make powerful 3D maps of forest canopy height using the ETH Global Canopy Height dataset. You will learn how to download and process the data, and how to render a crisp 3D map of forest height in Portugal. Whether you are a beginner or an expert in R, this tutorial will help you unleash your creativity and explore the beauty and diversity of forests around the world.🌲🌳🌴
