| MIRBI Algorithm Specification | |
The MIRBI operator algorithm computes the
Mid-Infrared Burn Index
from a given product.
The MIRBI results from the following equation:
MIRBI = 10.0 * S2 - 9.8 * S1 + 2.0
, where:
The bands are:
- S1 is the SWIR 1 band
- S2 is the SWIR 2 band
Also the processor computes an additional flags band called 'mirbi_flags' with the following bit coding:
| Bit Position | Description |
|---|---|
| Bit 0 | The computed value for MIRBI is NAN or is Infinite |
| Bit 1 | The computed value for MIRBI is less than -1 (minus one) |
| Bit 2 | The computed value for MIRBI is greater than 1 (one) |
