EVI2

The EVI2 operator algorithm computes the Two-Band Enhanced Vegetation Index from a given product.

The EVI2 results from the following equation:

EVI2 = g * (N - R) / (N + 2.4 * R + l)

, where:

The bands are:

- R is the Red band
- N is the NIR band

and the coefficients are:

- g is the Gain factor coefficient
- l is the Canopy background adjustment coefficient

EVI2-Flags

Also the processor computes an additional flags band called 'evi2_flags' with the following bit coding:

Bit Position	Description
Bit 0	The computed value for EVI2 is NAN or is Infinite
Bit 1	The computed value for EVI2 is less than -1 (minus one)
Bit 2	The computed value for EVI2 is greater than 1 (one)
