🍁 Fall foliage at Nose Hill Park: nature’s annual stress-test for remote sensing ML models.
🍂 As chlorophyll degrades, the NIR reflectance drops sharply, completely reshaping the NDVI signature of aspen stands and native fescue grasslands. Supervised classifiers (like Random Forest) trained solely on peak-summer composites quickly stumble when seasonal phenology drifts, often misclassifying senescent canopy as sparse ground or bare soil.
🛰️ Nothing beats on-the-ground validation to remind you what actual spatial heterogeneity looks like inside a single 10m/30m pixel.
