Improving Forest Loss Mapping In Nepal Using Landtrendr Time-Series And Machine Learning
--
https://doi.org/10.1016/j.rsase.2025.101864 <-- share paper
--
βHIGHLIGHTS:
β’ ViT-based forest mask, multispectral ensemble LandTrendr and terrain shadow mask.
β’ District-level RF/XGBoost model training with expert-weighted validation.
β’ Outperformed GFC and REDD + AI benchmarks in accuracy and F1 performance.
β’ RF excelled in High Mountains/Himalayas; XGBoost in the lower Mountain regions.
β’ NBR contributed the most; snow-impacted forest loss uncertainty was observed..."
