| NBRT2 Algorithm Specification | |
The NBRT2 operator algorithm computes the
Normalized Burn Ratio
Thermal 2 from a given product.
The NBRT2 results from the following equation:
NBRT2 = ((N / (T / 10000.0)) - S2) / ((N / (T / 10000.0)) +
S2)
, where:
The bands are:
- N is the NIR band
- S2 is the SWIR 2 band
- T is the Thermal band
Also the processor computes an additional flags band called 'nbrt2_flags' with the following bit coding:
| Bit Position | Description |
|---|---|
| Bit 0 | The computed value for NBRT2 is NAN or is Infinite |
| Bit 1 | The computed value for NBRT2 is less than -1 (minus one) |
| Bit 2 | The computed value for NBRT2 is greater than 1 (one) |
