Normalized Difference Vegetation Index (NDVI): Say no to plagiarism. Get a tailor-made essay on "Why Violent Video Games Shouldn't Be Banned"? Get an original essayNormalized difference vegetation index proposed by Rouse et.al. (1973), NDVI is a measure of healthy, green vegetation. The combination of its normalized difference formulation and the use of chlorophyll's higher absorption and reflectance regions make it robust across a wide range of conditions, the value of this index varies from -1 to 1. The common range for green vegetation is from 0.2 to 0.8. Atmospheric resistant vegetation index (ARVI): the main advantages of this index is its resistance to atmospheric effects, compared to the normalized difference vegetation index that is obtained by a self-adjusting procedure for atmospheric influence on the red band, using the difference in brightness between the blue and red bands to correct the brightness in the red band. Simulations using radiative transfer calculations on arithmetic and natural surface spectra, for numerous atmospheric conditions, show that ARVI has a similar dynamic range to NDVI, but is less sensitive to atmospheric effects than NDVI [9]. The formula for ARVI for narrowband data is as follows.ARVI: (?864 - [2 × ?671 - ?467])/(?864 + [2 × ?671 - ?467]) Difference Vegetation Index normalized red edge difference ( RENDVI): Normalized red edge difference vegetation index: reflectance near 700 nm was found to be very sensitive to the position of the red edge and the chlorophyll concentration [10] RENDVI provides a value normalized to the length of wave of 752 nm and 701 nm the equation for this index is as given in the equation.RENDVI= (p752 - p701)/(p752 + p701)Modified Difference Normalized Red Edge Vegetation Index (MRENDVI): This index is a modification of the Red Edge NDVI that corrects the specular reflection of the leaves. It exploits the sensitivity of the red vegetation edge to small changes in canopy foliage content, gap fraction, and senescence. Applications include precision agriculture, forest monitoring and vegetation stress detection. The value of this index varies from -1 to 1. The common range for green vegetation is between 0.2 and 0.7. See narrowband definitions for allowable range of wavelengths.

It is not the simple index of the ratio, it is the index of the normalized difference. It increases with increasing water content in the canopy, its range is from -1 to 1, for green vegetation it varies from 0.02 to 0.6.
