| CIG Algorithm Specification | |
The CIG operator algorithm computes the
Chlorophyll Index Green
from a given product.
The CIG results from the following equation:
CIG = (N / G) - 1.0
, where:
The bands are:
- G is the Green band
- N is the NIR band
Also the processor computes an additional flags band called 'cig_flags' with the following bit coding:
| Bit Position | Description |
|---|---|
| Bit 0 | The computed value for CIG is NAN or is Infinite |
| Bit 1 | The computed value for CIG is less than -1 (minus one) |
| Bit 2 | The computed value for CIG is greater than 1 (one) |
