| NBRplus Algorithm Specification | |
The NBRplus operator algorithm computes the
Normalized Burn Ratio
Plus from a given product.
The NBRplus results from the following equation:
NBRplus = (S2 - N2 - G - B) / (S2 + N2 + G + B)
, where:
The bands are:
- B is the Blue band
- G is the Green band
- N2 is the NIR 2 band
- N is the NIR band
- S2 is the SWIR 2 band
Also the processor computes an additional flags band called 'nbrplus_flags' with the following bit coding:
| Bit Position | Description |
|---|---|
| Bit 0 | The computed value for NBRplus is NAN or is Infinite |
| Bit 1 | The computed value for NBRplus is less than -1 (minus one) |
| Bit 2 | The computed value for NBRplus is greater than 1 (one) |
