| NRFIg Algorithm Specification | ![]() |
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
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) |
