| RDVI Algorithm Specification | |
The RDVI operator algorithm computes the
Renormalized Difference
Vegetation Index from a given
product.
The RDVI results from the following equation:
RDVI = (N - R) / pow((N + R) , 0.5)
, where:
The bands are:
- R is the Red band
- N is the NIR band
Also the processor computes an additional flags band called 'rdvi_flags' with the following bit coding:
| Bit Position | Description |
|---|---|
| Bit 0 | The computed value for RDVI is NAN or is Infinite |
| Bit 1 | The computed value for RDVI is less than -1 (minus one) |
| Bit 2 | The computed value for RDVI is greater than 1 (one) |
