Classify by Height Above Ground
Brief
This function classifies the points on the surface of the terrain with a certain height, which can quickly classify vegetation at different heights. For example, this classification can be performed three times to separate low vegetation (0-1m), medium vegetation (1-10m), and high vegetation (10-100m), see the figure below.
