  1. Spectral Discussion VIRIS Visible/InfraredIntelligent Spectrometer

  2. White Pine Spectral Curve & Landsat Band Regions Leaf Pigments Cell Structure Water Content NIR 1 Red Edge Water Absorption TM5 (MIR) TM2 (Green) NIR 3 Water Absorption TM7 (MIR) TM1 (Blue) TM3 (Red) Lignin TM4 (NIR) Cellulose

  3. Red Edge Inflection Point (REIP)

  4. Relationship Between Chlorophyll Concentration and REIP Values (Taken From Moss and Rock, 1991)

  5. Chlorophyll Absorption http://www.chm.bris.ac.uk/motm/chlorophyll/chlorophyll_h.htm

  6. Spectral Indices

  7. REIP – The Red Edge Inflection Point, a strong indicator of Chlorophyll Content (the higher the number, the greater the amount); Spectral Indices

  8. REIP – The Red Edge Inflection Point, a strong indicator of Chlorophyll Content (the higher the number, the greater the amount); NDVI – The Normalized Difference Vegetation Index, an indicator of “Greenness” (the higher the number, the greener the foliage); Spectral Indices

  9. REIP – The Red Edge Inflection Point, a strong indicator of Chlorophyll Content (the higher the number, the greater the amount); NDVI – The Normalized Difference Vegetation Index, an indicator of “Greenness” (the higher the number, the greener the foliage); TM 5/4 Ratio – An indicator of Wetness or Dryness (the higher the number, the drier the foliage); Spectral Indices

  10. REIP – The Red Edge Inflection Point, a strong indicator of Chlorophyll Content (the higher the number, the greater the amount); NDVI – The Normalized Difference Vegetation Index, an indicator of “Greenness” (the higher the number, the greener the foliage); TM 5/4 Ratio – An indicator of Wetness or Dryness (the higher the number, the drier the foliage); The NIR 3/1 Ratio – An indicator of Seasonal Development (the higher the number, the older the foliage). Spectral Indices

  11. Chlorotic Mottle Stomatal Rows
