  rdf:value "Transformación de mediciones satelitales computadas como la relación de reflectancia en las porciones roja e infrarroja cercana del espectro. La reflectancia en la región roja disminuye con el creciente contenido de clorofila de la copa de la planta, mientras que la reflectancia en la región infrarroja aumenta con la creciente biomasa vegetal húmeda. El valor de índice representa el verdor, la densidad y el vigor de la vegetación."@es, "A transformation of satellite-based measurements computed as the ratio of reflectance in the red and near-infrared portions of the spectrum. Reflectance in the red region decreases with increasing chlorophyll content of the plant canopy, while reflectance in the infrared increases with increasing wet plant biomass. The index value represents greenness, density, and vigor of vegetation."@en ;
