GRVI Algorithm Specification

GRVI

The GRVI operator algorithm computes the Green Ratio Vegetation Index from a given product.

The GRVI results from the following equation:

GRVI = N / G

, where:

The bands are:

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


GRVI-Flags

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

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