vegetation indices

Vegetation indices are mathematical tools used to measure plant health and density using data from satellite or aerial images. They analyze how plants reflect sunlight, especially in specific wavelengths like near-infrared and visible light. Healthy vegetation reflects more near-infrared light and less visible light, allowing these indices to quickly assess the condition of crops, forests, or grasslands. They help monitor growth, identify stressed plants, and inform farming or environmental decisions efficiently without physical inspection. Essentially, vegetation indices turn complex image data into simple, actionable insights about plant vitality over large areas.
