Spectral signature of healthy vegetation?
Plain English (default view) — short, conversational, lightly seasoned with science
🔬 Scientific / formula (revealed on click) — markdown + $$…$$ ok
- **Low red reflectance** — chlorophyll absorbs red for photosynthesis. - **High NIR reflectance** — scattered by spongy mesophyll leaf structure. That contrast is why NDVI, SR, and EVI all work.
💡 Mnemonic / memory aid (shown on hover)
Leaves DRINK red (chlorophyll eats it), BOUNCE NIR. That 'red dip, NIR jump' is THE vegetation fingerprint.
