| NBLI Algorithm Specification | |
The NBLI operator algorithm computes the
Normalized Difference
Bare Land Index from a
given product.
The NBLI results from the following equation:
NBLI = (R - T) / (R + T)
, where:
The bands are:
- R is the Red band
- T is the Thermal band
Also the processor computes an additional flags band called 'nbli_flags' with the following bit coding:
| Bit Position | Description |
|---|---|
| Bit 0 | The computed value for NBLI is NAN or is Infinite |
| Bit 1 | The computed value for NBLI is less than -1 (minus one) |
| Bit 2 | The computed value for NBLI is greater than 1 (one) |
