| NormNIR Algorithm Specification | |
The NormNIR operator algorithm computes the
Normalized NIR from a given
product.
The NormNIR results from the following equation:
NormNIR = N / (N + G + R)
, 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 'normnir_flags' with the following bit coding:
| Bit Position | Description |
|---|---|
| Bit 0 | The computed value for NormNIR is NAN or is Infinite |
| Bit 1 | The computed value for NormNIR is less than -1 (minus one) |
| Bit 2 | The computed value for NormNIR is greater than 1 (one) |
