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