| MLSWI26 Algorithm Specification | |
The MLSWI26 operator algorithm computes the
Modified Land Surface
Water Index (MODIS Bands
2 and 6) from a given product.
The MLSWI26 results from the following equation:
MLSWI26 = (1.0 - N - S1) / (1.0 - N + S1)
, where:
The bands are:
- N is the NIR band
- S1 is the SWIR 1 band
Also the processor computes an additional flags band called 'mlswi26_flags' with the following bit coding:
| Bit Position | Description |
|---|---|
| Bit 0 | The computed value for MLSWI26 is NAN or is Infinite |
| Bit 1 | The computed value for MLSWI26 is less than -1 (minus one) |
| Bit 2 | The computed value for MLSWI26 is greater than 1 (one) |
