Imagine getting an entire health workup just by having your picture taken -- no invasive poking or prodding, not even a pinprick blood test. That's a goal ecologists have for monitoring the health of plants. Their cameras would be high-resolution sensors mounted on drones or satellites, capable of capturing much more than what's visible to the naked eye. Brookhaven Lab scientists have developed robust models to translate 'spectral fingerprints' into information scientists can use to address challenges in agriculture, ecology, and more.
