文摘
- •
The paper shows the potential of airborne LiDAR in combination with Landsat for estimating timber volume on a large scale.
- •
We analyze the potential of the German National Forest Inventory data for usage as terrestrial reference for interpolating timber volume.
- •
We show the excellent functioning of generalized additive models (GAM) for large scale timber volume estimations.
- •
The study reveals that human impact on forest strongly influence timber volume estimations.
