Summary: A farmer at the foot of a corn stalk can tell how well the plant is faring. That same farmer might survey his entire field for crop health. But assessing the health of crops or forests at regional, national, and international scales requires remote sensing, most often via satellite. In this episode of Eyes on Earth, we talk to Jesslyn Brown about the Normalized Difference Vegetation Index (NDVI), a tool that uses the broader electromagnetic spectrum to estimate plant health.
