| NBLIOLI Algorithm Specification | |
The NBLIOLI operator algorithm computes the
Normalized Difference
Bare Land Index for
Landsat-OLI from a given product.
The NBLIOLI results from the following equation:
NBLIOLI = (R - T1) / (R + T1)
, where:
The bands are:
- R is the Red band
- T1 is the Thermal 1 band
- T is the Thermal band
Also the processor computes an additional flags band called 'nblioli_flags' with the following bit coding:
| Bit Position | Description |
|---|---|
| Bit 0 | The computed value for NBLIOLI is NAN or is Infinite |
| Bit 1 | The computed value for NBLIOLI is less than -1 (minus one) |
| Bit 2 | The computed value for NBLIOLI is greater than 1 (one) |
