SECTION 5 · VALIDATION GALLERY · DETECTION MODEL · t=0·60

Per-LGU visual validation of the detection model.

Each panel shows, for one LGU: the Sentinel-2 RGB basemap, the NDVI v0 baseline in orange, where the detection model confirms canopy in green, and where it differs from the NDVI rule in yellow (a difference, not a verified correction). The detection model is a CLIP ViT-Large/14 head with a gradient-boosted regression onto Meta's 1 m canopy fraction; on held-out locations it reaches R² 0.83 to 0.86 under grouped cross-validation against Meta's 1 m reference (its calibration target, not independent ground truth) and is being optimized toward a first release. Panels are sorted by the model's canopy percentage at threshold t = 0.60.
