Abstract

What are the main findings?· A new UAV-QField leaf-canopy validation approach was used to validate tree species in complex natural mixed forests.· Multi-temporal UAV imagery facilitated the manual annotation of closed canopies in mixed forests.· The multi-class and species-specific Mask R-CNN models showed differential performance for tree detection.
Keywords: deep learning; mask R-CNN; precise remote sensing; tree species classification; UAV deep learning; mask R-CNN; precise remote sensing; tree species classification; UAV
