The MTVI2 operator algorithm computes the Modified Triangular Vegetation Index 2 from a given product.

The MTVI2 results from the following equation:

MTVI2 = (1.5 * (1.2 * (N - G) - 2.5 * (R - G))) / pow((pow((2.0 * N + 1) , 2) - (6.0 * N - 5 * pow(R , 0.5)) - 0.5) , 0.5)

, where:

The bands are:

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

Also the processor computes an additional flags band called 'mtvi2_flags' with the following bit coding:

Bit Position	Description
Bit 0	The computed value for MTVI2 is NAN or is Infinite
Bit 1	The computed value for MTVI2 is less than -1 (minus one)
Bit 2	The computed value for MTVI2 is greater than 1 (one)
