Detailed Description

Slope based vegetation indices.

  • Difference Vegetation Index DVI = NIR - R
  • Normalized Difference Vegetation Index (Rouse et al. 1974) NDVI = (NIR - R) / (NIR + R)
  • Ratio Vegetation Index (Richardson and Wiegand, 1977) RVI = R / NIR
  • Normalized Ratio Vegetation Index (Baret and Guyot, 1991) NRVI = (RVI - 1) / (RVI + 1)
  • Transformed Vegetation Index (Deering et al., 1975) TVI = [(NIR - R) / (NIR + R) + 0.5]^0.5
  • Corrected Transformed Ratio Vegetation Index (Perry and Lautenschlager, 1984) CTVI = [(NDVI + 0.5) / abs(NDVI + 0.5)] * [abs(NDVI + 0.5)]^0.5
  • Thiam's Transformed Vegetation Index (Thiam, 1997) RVI = [abs(NDVI) + 0.5]^0.5
  • Soil Adjusted Vegetation Index (Huete, 1988) SAVI = [(NIR - R) / (NIR + R)] * (1 + S)
(NIR = near infrared, R = red, S = soil adjustment factor)
