| CVI Algorithm Specification | |
The CVI operator algorithm computes the
Chlorophyll Vegetation
Index from a given product.
The CVI results from the following equation:
CVI = (N * R) / pow(G , 2.0)
, where:
The bands are:
- G is the Green band
- R is the Red band
- N is the NIR band
Also the processor computes an additional flags band called 'cvi_flags' with the following bit coding:
| Bit Position | Description |
|---|---|
| Bit 0 | The computed value for CVI is NAN or is Infinite |
| Bit 1 | The computed value for CVI is less than -1 (minus one) |
| Bit 2 | The computed value for CVI is greater than 1 (one) |
