| DSWI2 Algorithm Specification | |
The DSWI2 operator algorithm computes the
Disease-Water Stress
Index 2 from a given product.
The DSWI2 results from the following equation:
DSWI2 = S1 / G
, where:
The bands are:
- G is the Green band
- S1 is the SWIR 1 band
Also the processor computes an additional flags band called 'dswi2_flags' with the following bit coding:
| Bit Position | Description |
|---|---|
| Bit 0 | The computed value for DSWI2 is NAN or is Infinite |
| Bit 1 | The computed value for DSWI2 is less than -1 (minus one) |
| Bit 2 | The computed value for DSWI2 is greater than 1 (one) |
