The Modified Triangular Vegetation Index 2 (MTVI2) is a vegetation index used for assessing vegetation health, especially in areas with high levels of chlorophyll and a wide range of land cover types. MTVI2 values typically range from -1 to 1, with higher values indicating healthier and more chlorophyll-rich vegetation. This index is useful for monitoring vegetation stress and assessing vegetation conditions in agricultural and environmental applications.

MTVI2 = 1.5 ( 1.2 ( 800nm − 550nm ) − 2.5 ( 670nm − 550nm ) / ( 2800nm + 1 ) ^ 2 − ( 6800nm − 5 ( 670nm ) ^ 0.5 ) − 0.5)
