- •
We develop a method to delineate patches in a tropical forest using LiDAR data.
- •
Trees identified from a Canopy Height Model are clustered using k-medoids.
- •
Patches based on Thiessen polygons reduce edge effects associated with grid cells.
- •
The method has relevance in landscape ecology for estimating habitat fragmentation.
- •
Patch-based models could improve carbon stock estimations in tropical forests.
