Extract Raster Values Using Vector Boundaries in R

This lesson reviews how to extract pixels from a raster dataset using a vector boundary. We can use the extracted pixels to calculate mean and max tree height for a study area (in this case a field site where we measured tree heights on the ground. Finally we will compare tree heights derived from lidar data compared to tree height measured by humans on the ground.
