| CSI Algorithm Specification | |
The CSI operator algorithm computes the Char
Soil Index from a given product.
The CSI results from the following equation:
CSI = N / S2
, where:
The bands are:
- N is the NIR band
- S2 is the SWIR 2 band
Also the processor computes an additional flags band called 'csi_flags' with the following bit coding:
| Bit Position | Description |
|---|---|
| Bit 0 | The computed value for CSI is NAN or is Infinite |
| Bit 1 | The computed value for CSI is less than -1 (minus one) |
| Bit 2 | The computed value for CSI is greater than 1 (one) |
