Leaves.PH: Metro Manila tree-canopy series

Open per-LGU and per-barangay annual tree-canopy estimates for the 17 LGUs of Metro Manila (2019 to 2026), measured from Sentinel-2 imagery with a human-calibrated classifier. Canopy here is a dense-vegetation proxy, not a pixel-exact tree census. Read each year as a cross-sectional snapshot, not a validated change series.

What is in this repo

• per_lgu/per_lgu_canopy_2019_2026.csv, per_barangay/per_barangay_canopy_2019_2026_model.csv: the published canopy series.
• MODEL_CARD.md, BENCHMARKS.md, RESULTS.md: accuracy, intended use, known biases, and the 656-label evaluation. All metrics live here.
• canopy_model/: the published classifier, its 656 manual gold labels, and the ablation it was chosen from.
• validation_v3/*.png: per-LGU visual validation panels.

The CLIP detection artefacts are a separate research track (in optimization) and are not the source of any published figure.
