NRFIg Algorithm Specification

NRFIg

The NRFIg operator algorithm computes the Normalized Rapeseed Flowering Index Green from a given product.

The NRFIg results from the following equation:

NRFIg = (G - S2) / (G + S2)

, where:

The bands are:

- G is the Green band
- S2 is the SWIR 2 band


NRFIg-Flags

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

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