Spectral Indices
9
REIP – The Red Edge Inflection Point, a strong indicator of Chlorophyll Content (the higher the number, the greater the amount);
10
Spectral Indices 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);
11
Spectral Indices 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 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).
