  description: 'Modified Triangular Vegetation Index 2 (Haboudane 2004). A

    structural index designed to correlate with LAI while staying

    robust to chlorophyll variability. ESRI''s choice signals its

    enterprise relevance for canopy-structure mapping.

    '
  use_cases:
  - Leaf-area-index estimation in row crops and forest canopies
  - LAI-saturation-robust greenness over dense canopies where NDVI saturates
  - Component of the MCARI/MTVI2 ratio for chlorophyll-structure separation
  limitations:
  - Complex formulation makes per-pixel interpretation harder than NDVI-class indices
  - Requires careful atmospheric correction since it uses three bands
  - Saturates at very high LAI like all structural indices, just at a higher threshold
  interpretation:
    high: Dense canopy with high LAI
    mid: Moderate canopy
    low: Sparse vegetation, soil
