GRVI (Green Normalized Difference Vegetation Index)

Green Ratio Vegetation Index (GRVI) measures vegetation health and vigor by comparing the reflectance of green and red light from the Earth's surface. It is sensitive to chlorophyll content and photosynthetic activity, making it effective for assessing plant vitality. GRVI values range from -1 to +1, where higher values indicate healthier and more vigorous vegetation, while lower values suggest stressed, sparse, or non-vegetated areas. It is useful for monitoring crop health, detecting plant stress, and managing agricultural productivity.
