Forest Digital Terrain Model from Copernicus GLO-30 DEM and GEDI L2A Using an Explainable Boosting Machine
Accurate ground elevation beneath forest canopies is important for terrain and forest-structure analysis, yet satellite-based elevation data can be affected by canopy and terrain conditions, while spaceborne light detection and ranging (LiDAR) provides ground elevations only at discrete locations. Here, the elevation o...
