| RENDVI Algorithm Specification | |
The RENDVI operator algorithm computes the Red
Edge Normalized
Difference Vegetation
Index from a given product.
The RENDVI results from the following equation:
RENDVI = (RE2 - RE1) / (RE2 + RE1)
, where:
The bands are:
- RE1 is the Red Edge 1 band
- RE2 is the Red Edge 2 band
- R is the Red band
Also the processor computes an additional flags band called 'rendvi_flags' with the following bit coding:
| Bit Position | Description |
|---|---|
| Bit 0 | The computed value for RENDVI is NAN or is Infinite |
| Bit 1 | The computed value for RENDVI is less than -1 (minus one) |
| Bit 2 | The computed value for RENDVI is greater than 1 (one) |
